206 PROCEEDINGS OF SOCIETIES. 



the circulation in a frog's foot could be watched for several consecu- 

 tive days, because having half an inch or more of water over it the 

 web could not become dry, and moreover there was no necessity for 

 irritating it in any way, whereas it was scarcely possible to avoid 

 irritating it if an immersion lens were made use of, because a single 

 drop of water only being used at a time this was constantly evap- 

 orating, and had as constantly to be renewed. In his opinion, for 

 class demonstration this method of showing circulation was superior 

 to every other, not even excepting the immersion-lens system. He 

 had himself used it for this purpose and had found it to answer 

 most admirably. 



Mr. Groves then said that if the sediment of a pint or more of 

 urine were emptied into a small flat glass dish with as little of the 

 urine as necessary, by means of the water-tight cap over an object 

 glass, the whole deposit could be examined in the course of a few 

 minutes, whereas if examined drop by drop on a slide, much of the 

 deposit would be lost and hours would be required for the examina- 

 tion of Buch as was secured. 



In the discussion which followed, Dr. Matthews, Dr. Foulerton, 

 Mr. Giles, Mr. Miller, Mr. Hogg, and Mr. White, took part. 



Mr. T. C. White described a small and painful tumour which he 

 had found in the cavity of a decayed tooth. 



Mr. Hogg read notes and exhibited specimens of a case of 

 Bright's disease. 



In the discussion which followed Mr. Hogg's remarks the follow- 

 ing gentlemen took part, viz. Dr. Matthews, Dr. Foulerton, Dr. 

 Bruce, Mr. Atkinson, Mr, Needham, Mr. Stowers. 



Mr. Hogg exhibited charts of the spectra of chlorophyll. 



Mr. White considered that probably at some future time charts 

 of the spectra of chlorophyll might prove of great service in medico- 

 legal inquiries. 



The first annual meeting of this society was held January 16th, 

 at 8 p.m. o'clock, at the Boyal Westminster Ophthalmic Hospital, 

 Jabez Hogg, Esq., President, in the chair. From the report of 

 the committee it appeared that the society, though only one year 

 old, was in a most flourishing condition. During the year 129 

 members had joined it and sixteen papers had been read, each of 

 which was followed by a lively discussion, and at no meeting was 

 there any lack of specimens for exhibition. 



The following gentlemen were elected officers for the ensuing 

 year : — President, Mr. Jabez Hogg ; Vice-presidents, Mr. W, B. 

 Kesteven and Drs. H. Lawson, J. F. Payne, and W. Eutherford ; 

 Treasurer, Mr. T. C.White ; Hon. Secretaries, Messrs. C. H. Golding 

 Bird and J. W. Groves ; Committee, Drs. M. Bruce, E. C. Baber,
