1892.] MICROSCOPICAL JOURNAL. 203 



inspect the company's works. The matter was referred to the 

 local committee. 



Tuesday Evening. 



The evening session was devoted to the reading of the pres- 

 idential address. In spite of the extreme heat and the technical 

 nature of the subject there was a fair attendance at Music Hall. 

 The subject was " The Relation of the Microscope to the Ad- 

 ministration of Justice." 



We hope to publish Prof Ewell's address in full in an early 

 number of the Jozirnal. 



Wednesday Morning. 



The following committee on nominations was suggested : Mr. 

 Hyath, Professor Gage, Professor Miller, Professor Kellicott, E. 

 Bausch, Dr. Deck, Professor Krauss. Mr. Miller withdrew his 

 name and the other seven were elected. 



The first paper of the day was then read by Prof. Gage, on 

 '•'• Methods of Decalcification in which the Structural Elements 

 are Preserved." Prof. Gage gave a practical illustration of this 

 method, using part of the rib of a cat. Among other things, he said : 



'•Bone used to be studied in sections, as rock now is, but the 

 living part of the bone is far more important than the dead struc- 

 ture. How, then, can we get rid of the bony part and save the 

 live protoplasmic elements.^ It is a fatal blunder to put bone 

 while fresh into the decalcifying substance, for thus the live parts 

 are ruined. It should be treated more as a muscle or piece of 

 tissue. I advocate hardening the whole bone in picric alcohol, 

 as for muscle, and then putting in 67 per cent, of alcohol with 3 

 per cent, of nitric acid. Thus the alcohol restrains the decalcify- 

 ing action of the nitric acid. The bone is never scraped, and is 

 put in collodium." 



Mrs. Gage gave an account of a method she had employed for 

 putting together sections of a whole where microscopic study had 

 to be done in sections. Her suggestion was a modification of 

 the card catalogue system used in libraries. She exhibited a 

 series of magnified sections upon cardboard arranged upon her 

 plan. 



Dr. W. C. Krauss read a paper on the diagnosis of tumors. 



New members were elected as follows : Adolph Lomb, 

 Rochester ; S. A. Ellis, Rochester ; Dr. T. Eugene Oertel, 

 Washington ; E. F. Bigelow, Portland, Conn. ; Charles U. 

 Amelie, Rochester, Minn. ; Professor Bentley, Chicago, 111. 



The remainder of the session was occupied by a discussion of 

 plans for a working session at the meeting at the World's Fair 

 next summer. 



Wednesday Afternoon. 



The society met at 2 o'clock in Sibley Hall and listened to a 

 very interesting lecture by Rev. D. W. Smith on "Recent Re-
