ABSTRACTS OF THE PROCEEDINGS OF THE CHEMICAL SOCIETY. ~ ~~~~ No. 60. Session 1888-89. ~ December 20th, 1888. Mr. W. Crookes, F.R.S., President, in the Cliair. Mr. Frank Bower was formally admitted a Fellow of the Society. Certificates were read for the first time in favour of Messrs. P. Carmody, F.I.C., The Laboratory, Somerset House ; Edward Mitchell C haplin, Westgate, Wakefield ; John Curragh, Donsghsdee, Belfast ; David Ferrier, The Cotta,ge, 50, High Street, Montrose ; Conrad Geriand, Church, Idancashire ; Alfred Miall Hanson, The Marjorie, Whalley, near Blackburn ; Henry Joshua Phillips, Great Western Railwq Laborstory, Swindon ; Thomas John Underhill, 43, Chapel Road, West Norwood, S.E. The following papers were read :-96. " On some Leadhills Minerals." By Korman Collie, Ph.D.Up to the present time, the analyses of the rare lead minerals which are to be found at the Leadhills in the southern highlands of Scotland, have been both meagre and contradictory. The author communicates a number of analyses of some specimens of lendhillite, lanarkite, vanadinite and other minerals, obtained from Dr. Wilson of Wanlock-head, Leadhills, and also of a considerable number collected by himself. The investigation was undertaken for two reasons ;the chief one being to ascertain whehher in the large number of double carbon- ates, sulphates, phosphates, &c., found at Leadhills, the constituent salts were always present in molecular proportions, or wbether they were only isomorphous mixtures. The other reason was to determine which among the conflicting analyses met with in the mineralogical treatises were the most probably correct. Two new minerals were met with :-(1.) A pyromorphite, containing both copper oxide and vanadic acid; (2.) an aragonite in which part of the calcium car-bonate had been displaced by lead carbonate.122 The other minerals analysed were leadhillite, lanarkite, caledonite, linarite, vanadinite, pyromorphite, plumbocalcite, calamine, dolomite, and strontianite. 97. “Metallic Derivatives of Halogon Nitrophenols.” By Arthur R. Ling. Chlorobromoparnnitrophenol, prepared by brominating chloropara- nitrophenol, m. p. 110”,in acetic acid solution, separates from boiling water in colourless crystals melting at 137”with decomposition.The following metallic derivatives of this phenol are described :-Potassium salt,, CfiH2C1BrN0,R*H20,golden-yellow needles. Calcium salt, (C,H,CIBrNOs),Ca-9H2O, yellow needles. 7, (C6H2C1BrN03)2Ca.4H20,yellow plates. Barium salt, (C,H,C1BrNO3),Ba*10H20, yellow needles. ,, (C6HzClBrN0,)2Ba.3~Hz0,red needles. The calcium-derivatives of the following were also examined :-Dibromorthonitrophenol, red plates, containing 7 mols. HZO. Dichlororthonitrophenol, orange-yellow fibrous needles containing 1mol. HzO. Dichlororthonitrophenol, red crystals, containing 4 mols. H,O. Parachlororthobromorthonitrophenol,red plates, containing 4H,O. Pnrabromorthoiodorthonitrophenol, red plates, containing 4H20. They are almost insoluble in cold and only sparingly soluble in boiling water. A general feature of the calcium-derivatives of the nitrophenols, especially those of the orthonitro-series, seems to be the difficulty with which the water of crystlallisation is removable on heating, e.g., it was found impossible to completely dehydrate calcium dibromortho- nitrophenol below a temperature at which it decomposed. The author also points out that as they lose their water of crystallisation, the calcium orthonitrophenol-derivatives change from red to an orange colour, which is at variance with the conclusions of Carnelley and Alexander.
