ON Weduesday, tlie 13th of June, a Conversazioiic was given by the President, Dr.James Bell, F.R.S., at the Marlborough Rooms, Regent Street, London, and was in cvcry way a success. The exhibits, nearly 40 in number, were of unusual beauty and interest, comprising, not only apparatus and cl~cmical specimens, but also some receut discoveries experiiiientdly illustrated. Dr. Armstrong exhibited speciineiis illustrative of isomerism and isomeric change. Mr. G. Stillingfleet Johnson sent tlie peculiar form of creatiniiie he has obtained from huinau urine ; and Dr. Hugo Muller qnercite from the leans of Ckm~rop humilis, and cocosite, a new substance resembling inosite con- tained in the leaves of several species of cocoanut palms. Messrs. Brooke, Sinipson and Spiller, had a fine collection of various dyes of the Rosaiiilne series, of the Eosin series, OF those formed from Azo-compounds, and also dyee of the new Primuline series.In the coal tar industry, also, the Badisclie Anilin and Sods Fabrik, and Professor Meldola had splendid exhibits of dyes obtained fi-om coal tar, whilst Messrs. Burt, Boulton and Haywood showed the varions derivatives of the benzene, naphthalene, and anthracene series from which these colours are manufactured. Messrs. Hopkin and Williams had a noteworthy collection of' fine chemicals, including beautifully crystallised plstinooyanides. The chemical apparatus was of varied kind, including numerous spectroscopes, polariscopes, and photometers, and there mas a good show of niicroscopcs ; one sent by JIessrs.Powell and Lealand bciug supplied wi tli $=tli apocliromatic homogeneous immersion objectire, nunieiical aperture 1.+lo,and an apochro-matic ho~nogeneousimmersion condenser, 1iumerica1aperture 1.-it), which showed the iiiarkiiigs on Apltiplsiim yellucida (Acus) \\ ith great distinctness. Professor S. U. Pickering exhibited a new mixing calorimeter, and an apparatus for breaking bulbs in il calorimeter. The calorimeter coiisists of a platiniini vessel divided into two coiii-partments by folding doors, wllicl~are made to fit water-tight by means of two springs and caoiitchouc lining. %%en tlie Iiquids in the two conipartments are at the same tenipernturc, tlie spriiigs are released by pressing together tlie eboiiite knobs connected with them, and tlie doors fly open.A stirrer, worked by an elect,roniotor, and a therinometcr is placed in each compartment. In the appai*atns for brenltiiig bulk, the bulb is held stationary by an inverted pltitiniini cone attached to a rod ; by liittirig thc upper end of this rod, the bulb is bidien at the proper moment. A disc of wire gauze prevents the broken glass from beiug knocked against the thermometer by the stirrer, wliich is in the liquid. Professor M'. Ramsay and Dr. S. Young liad three exhibits :-(1.) An apparatus for sliowing the temperature of mnxirnurn density of water, in which a glass bulb is weighted so as to have tlie exact specific gravity of n ater at 4" ; if the water is made either wjirnier or colder, it bcconies lighter than the bulb, which conseqiiently sinks.(2.) A T-apour-pressure therinonieter : In this tlie liquid is ether, containing a little nlcoliol in \\ hich a colouring nintter has bee11 dissolved. The vapuur prcssiire of the ether varies nit11 the temperature, forcing up the coluwn. llie divisions on the scale are not equal ; hcnce the scale must be divided by coniparison at certain knoj\-n temperatures with an accurate riiercurittl ther-niouie t er . (3.) The liquefactio~t of metliyl fluoride by compression TY~S 7 shown, the methyl fluoride beiiig very neai-ly pure ; it was prepared by heating tetremetliylamiiioninm fluoride. It liquifies at 0' under a pressure of about 15,OOi) millimeters, or tn-enty atmospheres. Undoubtedly the most attractive spot was the table at which Mr.C. Vincent Boys eshihited his experiments with soap bubbles ; the beauty of the experiments themselves, performed, as they were, Kith sucli surprising niaiiipulative skill, exerted a kid of fascination on the visitors who thronged the table from the opcnirig of tlie soirke until its close. These evperimeiits are arranged to shew chiefly the power of an air film to prevent two bubbles froiii coining into real contact. Thus, aniorig other evperiiiients, the outer of two bnbbles was pulled out until it squeezed the iiiner ow into a long oval, but no real contact takes place. An iiiuer bubble filled with gas will carry iip an outer one, to which are atlaclied a wire ring and other things withont the iiiuet I~ubbleredly touching the outer one at all.A bubble will roll down a spiral groove also riiadc of soap film, or jump one or two steps at it time down a spiral stair- case made of soap film, without touchiiig the spiral film or being injured in the least. The esperiineiits of Professers Ayrton aiid Perry with their maguifying springs were also of great interest. The principles on which this elegant method of inicroiiietric measurement is founded, niay be briefly explained as follows :-The end of an ordinary spiral spriiig made of round wire, such as is used in a spring balance, does not appreciably rotate wlieii the spring is stretched, so that mlieii it is desired to magnify the extensioii it is 1iece.ssary to emp!oy a wlieel arid piuioii or levers, or some sucli coiitrivance, which has the defect of introduciiig friction, back-lash, and in dditioii, makes it difficult for siiiall extensioiis to obtni 11 perfect proportionality between the esteiisioii of the spring and the rotation of the pointer.By making the metal flat, however, aiid winding it 1111 like a thin shaving, n spring is produced, the end of which turns throuyti a large angle for a small azial extension of the spriug, the rtitio of rotatiou to axial extension being the greater the siiialler the diameter of the spring. If the diameter of the spring l)e very sniall, for example, the -&atti of an irich, a complete rotation of the pointer is obtained by ail axial extensioii of tlie spring of less thari the i&th of aii inch. Specimens of tliese magnifying springs of various serisiblities were eshihitcd, and they were also sliotvn, as applied to spri1lg balances, electro-rnagnetic ammeters aid volt ni eters for mensuriII g direct currents aiid pressures, and a voltiiieter based 011 tlic espaiision of a short wire, for nieasnriiig alternating electric pressures.There was dso a large working model sho~iiigtlie principle of the expanding wire yoltmeter. II3esides these, there was the adaption of the flattened spiral spring to a siniple apparatus for mensuriiig the co-efficient of expansion produced by rise of teiiiperature, also to wieuum and pressure ganges aiid to thermometers. Lastly, there was a iiiiurometer constructed 011 this principle and indicating the one t~~~iity-thousandthof an incli.In the room dowiistairs there was a modal of Biin's oxygen producer shown in action by Dr. 1,. T. Thorile, the chemist to tlie company ; whilst oue use for tlie gas extracted fiorn the atiiiosphere by this modern modification of ail ancieut process, was illustrated by Fletcher's oxjgen blowpipe, which melted up thick wrought iron almost like wax. 'l'his model of Erin's oxygen producer is desigiied to sliew the method employed for obtaining oxygen from atmospheric air by means of barium oxide. Boussingdt lorig ago shewed that barium oxide when heated in a current of moist air absorbs oxygen, becoming conyerted iiit,o barium peroxide, and that this peroxide at R higher teiriperature again yields up lialf its osygeti, leaving baritiru oxide ready for re-oxidation.All attempts hitherto made to employ this method commercially for the pile-paration o€ oxygen hare failed, however, owing to the fact that the barium oxide, after a few operat>ions, gradually loses its power of absorbing oxygen. By special precautions in the pre- paration of tehe barium oxide, the drying and purification of the air used, and by improremeuts in the mechanical means used for slipplying the air and pumping off the oxygen, this difficulty has been overcome, and the barium oxide retains its activity almost indefinitely, so that the process can be employed for the con-tinuous production of oxygen on the commercial scale.Besides his powerful oxy-hydrogen bloiv-pipe, Mr. T. Fletcher exhibited various gas apparatus of interest to chemists, including ordinary blow-pipes, hot blast blow-pipe, gas reverberatory fur-nace, injector and tube furnaces, furnaces for the lecture table and muffle furnaces. OF gas burners, there were the high power burners, the drip proof burner, the new safety Bunsen, and duplex boiling burners of various forms. Among& the elect rid apparatus were telephones ; Robertson’s writing telegraph, by which an actual facsimile copy of the hand- writing is transmitted ; Wheatstone’s automatic recorder, used at the Post Ofice, and capable of transmitting 300 to 400 words per minute ; h4r. Eric Bruce’s signalling ballooti ; and Edison and Swan’s electrical safety Iarnps.Mr. Eric Stuart Bruce’s electrical translucent balloon for flashing signals by night, is intended to facilitate military night signalling to long distances and in places where ordinary signalling would be impracticable, such as wooded and hilly districts ; also for naval coast signalling in war, and to provide a feasible means of signalling in Arctic regions. The apparatus consists of a captive balloon made of a translucent material, several incandescent electric lamps, placed inside the balloon and supported on it specially devised holder in the form of a ladder, and lastly a metallic circuit connecting the lamps with a source of electrical 10 power on the ground ; a special form of key is employed in the circuit, on the ground, designed to carry light or heavy currents and to make and break contact rapidly ;in this key the contacts are of carbon and can be easily renewed as they wear away.The Edieon and Swan Company’s safety lamp for miners con-sists of a storage battery of four cells enclosed in a strong teak box turned out of the solid and strengthened with metal bands ; and a small incandescent lamp mounted on the side of the case, protected by a strong glass cover. The case is fitted with a hinged lid secured by a crossbar fastened with a safety nut, and having a swivel handle. The full size of the lamp is 7 inches by 4$ inches, and the weight of the whole ready for use is about 7 lbs. Mr. James Wimshurst had his large electrical influence machine in full action, and it worked splendidly.It has 12 disks, each 2 feet 6 inches in diameter and carrying 16 metal sectors. The machine, which becomes fully excited in any condition of atmosphere with one revolution of the handle, shows large and perfect brush discharge at its terminals ; with Leyden jars it will give a rapid succession of Bparks 188inches in length. A military band, with Mr. S. Dodwell (late Coldstream Guards) as conductor, gave a selection of music during the evening. MEETINGS OF COUNCIL. The new Council elected on March 1st has held the usual monthly meetings with an average attendance of 19 members at each meeting. During the three months ending June 30th, there have been 15 committee meetings, at which various imd portant matters connected with the welfare of the Institute have been discussed.11 BOARD OF EXANISERS.
