I am instructed by the Council to inform you that it will not be possible for any of our Fellows to be present personally on February 25th, but I am to ask you to be so good as to convey to Prof. Markownikoff the hearty congratulations of our Society, and to express the wish that he may be spared to carry on his valuable and important investigations for many more years. We 2 rejoice that your distinguished countryman’s name appears in our list of Foreign Members, and I beg you to convey to him the assurance that his long devotion to that science which he has done SO much to advance by his researches is most highly appreciated by English chemists.Yours obedient1y, RAPHAEL ISIELDOLA, Fweig 1L Sewetary, DR. H. DECKER. Of the following papers, t,hose marked ++ were read :-*1. ‘‘ The preparation of iodic acid.” By A, Scott and W. Arbuckle. The usual method of preparing iodic acid by gently boiling iodine with nitric acid in a flask with a long neck, is tedious when any quantity is required and liable to great loss of iodine unless the source of heat is very carefully regulated. By using, first the ordinary form. and later a modified form, of Soxhlet’s fat extraction apparatus to contain the iodine, almost theoretical yields of iodic acid were obtained after a very short treatment with the boiling nitric acid.The liability, however, of the siphon tube to become chokecl with crys- mls of iodic acid led to the abandonment of this type of apparatus. After many trials with various forms of apparatus, the authors recom- mend the use of a round-bottomeJ flask having a ground-in neck carrying two tubes, to one of mliich is sealed a reflux condenser, and through the other is fitted LZ tube by means of which a current of oxygen is passed through the boiling liquid. With this apparatus finely powdered iodine boiied with ten times its weight of fuming nitric acid may be completely oxidised in 20-30 minutes. “2. Note on isomeric change and meta-substitution in benzenoid amines.” By A.Lapworth. The rules deduced from the two simplest change forms (Trms., 1898, 73. 45’7) depend on the assuinption made imp!icitly throughout the paper, that only one group can “migrate ” along any chain of atoms at any instant, that is, that exchange of groups is, as a rule, the result of the successive migration of t’lie two groups in revwse direc- tions. This view appears in general to be well founded, and it is easily demonstratecl that if it holds true, the rules deduced are necessaiily correct, the second being used where the valencp of an atom alters. It is of no consequence whatever how the migration is effected, so far as the applicability of the rules is concerned. 3 Although in applying the rules it is sometimes convenient to assign successive positions of attachment of a labile group in its migration, it is not imagined that these are actually occupied, at least in the ordinary sense of the term.It may be supposed, for example, that the group is handed on in a still dissociated state from its initial to its final position, the others merely representing the possible places of attachment. The author hns advanced the view that naeta-substitution is the result of elimination of a hydrogen atom in the benzenoid nucleus (necessarily from the sneta-position) with a group in the complex formed by union of the side chain with the acting agent. Arm-strong has recently used a similar conception in explaining the formation of chloracetanilides from plienylacetylchloramines ;in the author's opinion, this would lead to the production of the metn-derivative, instead of, as is the case, the ortlio-and para-derivatives (compare Trcms., 1900, 77, 1051).In alluding to the formation of nzeta-sulphonic acids from benz-enoid amines (Zoc. cit., p. 457), the author suggested that it was the result of the migration of the -SO,H group in aniline sul-phates; this view must be rejected as impossible, as the necessary grouping is not present. The statement that metcc-derivatives are formed when the labile group 31 is separated from the benzene ring by two atoms only holds true when the grouping <->=X*Y*lI. is present or can be formed as an intermediate step.31: will migrate to the metmposition when separated by one atom on1-j-, from the nucleus if the intermediate compound is of the typo <>=X*M, and X is able to fall in valency by two units, for example, when X is a pentavalent nitrogen atom. Applying this to the case of the action of fuming sulphuric acid on dimethylaniline, the most probable explanation of the reaction is that dimethylaniline sulphate unites with sulphuric anhydride, and that from this compound sulphuric acid is then eliminated by loss of a hydrogen atom from the nucleus thus Me2 Me2 Me,.. ** N.SO,HiGSO,H Y<OSO,H Il H/\H H/\\H H H/"H // + H*OSO,H.= HI1IH''3 + = H(/ \/ '\ /H H H The latter substance must yield the meta-sulphonic acid if the sulpho-group then migrates, assuming, as usual, that the other atoms 4 retain their positions until this migration has ended.Or, expressing it in terms of the author’s rules, as the sulpho-group migrates the valency of the nitrogen must fall, since it cannot become attached to the nucleus by a treble binding ; $he nearest possible position of attachment for the labile group is, therefore, the P-position, hence, as the valencies of the carbon atoms remain cocstant, the next position must be imagined to be reached by an ay-change. This process can also be followed by using Thiele’s rule, but, in this case, it must be assumed that sulphuric acid is added in one way and eliminated in another, and as for this purpose it must he supposed that before addition it breaks up into HO and ‘SO,H instead of into H and OSO,H, the objection to this hypothesis is obvious.3. rL The preparation of esters from other esters of the same acid.” By T. S. Patterson and C. Dickinson. Experiments were described which had for their object the preparation of methyl ethyl tartrate. A substance was obtained having the observed rotation + 11-14’ at 18’ (I =200 mm.), which probably consisted chiefly of the compound sought. It showed no tendency to crystallise and as no method of purification, other than crystallisation, was likely to be suitable, these attempts to obtain a pure compound were abandoned. They had shown, however, that ethyl tartrate is largely converted into methyl tartrate by the action of methyl alcohol and hydrochloric acid.Experiments were then described showing that pure ethyl tartrate can be obtained from methyl tartrate and pure methyl tartrate from ethyl tartrate, by Fischer’s method, bence it is probable that any other ester may be prepared by an analogous process, under certain circumstances this might prove useful. Finally determinations of the rotation of methyl tartrate at temper-atures between 20’ and 100’ were given. 4. ‘‘ Tecomin. A colouring matter derived from ‘Bignonia tecoma’.” By T. H. Lee. The new colouring matter is a yellow, crystalline, substance soluble in alcohol with an orange colour, insoluble or very slightly soluble in water ;the solution becomes rose-red with alkalis and clear yellow with acids ; 2 C.C.N/100 alkali or acid causes the colour change ; it is not affected by any but the strong mineral acids, but the presence of organic acids renders the end reaction indistinct.The wood contains a reddish-brown resin soluble in alcohol from which it is difficult to free the tecomin; also a deep brown colouring matter which dissolves in aqueous alkalis and is precipitated by acids. It is used locally as a dye for cotton and as a stain for mood. 5. (‘Anew method for the measurement of ionic velocities in aqueous solution.” By B. D. Steele, B.Sc. The author described a new method for the direct measurement of ionic velocities in aqueous solution. Masson (Phil. Trans., 1899, 192, A, 331) has succeeded in obtaining satisfactory measurements in gelatine, and for a fern ions; Whetham (Phil.Tyans., 1893, 184,A, 337) has made measurements in water. The method now described should be a perfectly general one, as the use of coloured indicator solutions is no longer necessary, and hence the range of ions which may be used as indicators is largely increased. The method consists in enclosing the liquid to be measured between two partitions of gelatine, which contains the indicator ion in solution; on the passage of the current the cation of the solution is followed by the cation of the indicator, and the anion of the solution by the corresponding anion of the indicator. It is necessary in all cases that these indicator ions should move more slowly than the measured ion. The position of the boundary between the two solutions is easily seen, on account of the difference in refraction, and the motion is measured by means of a cathetometer.If the above-mentioned con- dition is fulfilled the relative velocity of the boundary is not influenced by changing the indicators, thus (CuSO, and K,CrO,), (CuSO, and NaC2H,0,), and (CdSO, and NaC,H,O,) all gave the same value for the transport number of MgSO,. The absolute velocity of a few ions has also been calculated and compared with the velocities found by Kohlrausch, and a very fair agreement is shown to exist between the two sets of measurements, 6. ‘‘Metal-ammonia compounds in aqueous solution. Part 11. The absorptive powers of dilute solutions of salts of the alkali metals.” By H.M. Dawson and J. McCrae. The influence exerted by the addition of salts of the alkali metals on the distribution of ammonia between water and chloroform at 20” has been investigated. It has been found that so long as the ammonia concentration in the aqueous phase is less than 0.5 normal, the altera- tion of the distribution coefficient is proportional to the salt concen- ~tration, that is, the expression k-k‘ is constant, where k is the n distribution coefficient with pure water (26*28), and k’ is the observed. distribution coefficient with salt solution of normality n. This constant it is proposed to call the ‘‘equivalent alteration of the distribution coefficient.” The alteration for each salt is composed sdditively of two vitlues, one dependent upon the cation, the other upon the anion.Since, according to the views of Abegg and Bodlander, “ammonia-complex ” formation tlakes place only with the cation, the differences in the values of the alteration for salts of one metal express the differences in the physical actions of t,he anions ; but differences in the values for salts containing the same anion do not measure the differences in the physical actions of the cations because of the complicating influence of complex formation. The lithium salts show the greatest t’endency to form ammonia addition compouncls, ammonium salts show it to a less degree, whilst for sodium salts it is probably very SIKLII, ilut greater than for potassium salts.When the ammonia concentration is greater than 0.5 normal, irregu- larities occur, and it has beeii found that foy increasing salt concen-i% -k’tration and constant ammonia concentration the value of -1L decreases, whilst for constant salt concentration and increasing aui- monia concentration it increases. Non-electrolytes (urea and cane sugar) also considerably affect the distribution coefficient, so that Dalton’s law is not obeyed. These results indicate that the solvent power of water is changed to a varying extent by the different ions. The intrinsic property of the ion which is the cause of this difference is not deducible from the ionic theory as it stands at present. 7. ‘(The amide, anilide, and toluidides (ortho- and para-) of glyceric acid.” By P.F. Frankland, F. M. Wharton, and H. Aston. These compounds have been prepared by the authors with the object of investigating the influence on the rotation produced by replacing the alkoxyl group by the amido-group and its substituted derivatives. Alter a review of the limited number of cases at present available for ascertaining these relations, the authors pointed out that so far it was observable that if in an homologous series of ethereal salts the rota- tion is raised by successive additions of CH,, then the amide has a similar but still higher rotation than the ethereal salts, but that if the successive additions of CH, lead to diminished rotation, then the corresponding amide has a lower rotation than the ethereal salts.The first of these relations is exhibited by the derivatives of tartaric, malic, and glyceric acids, whilst the only hitherto known example of the second is furnished by the corresponding derivatives of mandelie acid. The result of substituting in the amido-group appears in all cases to be an increase in the rotatory effect of the latter. In the case of malic acid, the anilide has a greater molecular rotation than the amide, the o-toluidide greater still, and the p-toluidide the greatest of all. In the case of glyceric acid, on the other hand, although the anilide has a greater molecular rotation than the amide, the rotation of the p-toluidide is less than that of the anilide, and the rotation of the o-toluidide is about the same as that of the amide.The amido-compounds prepared by the authors appear to be the only ones which have hitherto had their rotation determined in the liquid state ; in the case of the o-toluidide, however, this could unfortunately not be effected, as this, on fusion, at once acquired a strong colour. In consequence of this, the rotation of a11 the compounds in question was determined also in methyl alcohol solution. The corresponding compoiinds of inactive glyceric acid were also prepared, and their melting points compnred with those of the active substances. ANNIVERSARY DINNER.
