THE MICROSCOPE. 



After recrystallization the shape of the crystals becomes definite, 

 mostly appearing in their rhombic prisms. 



Mr. Wm. Hoskins spoke of the differences between the crystal- 

 lization of the fat of butter and that of lard, tallow, etc., etc. 



The speaker stated that upon melting and then cooling the 

 clarified fats slowly, the differences in the crystallization of the 

 various fats were very marked, and that he was enabled in this way 

 to distinguish positively adulterations of suine, oleomargarine, etc., 

 in butter. After some discussion the meeting was declared in- 

 formal.

THE BUFFALO MICROSCOPIC CLUB. 



The regular monthly meeting of the club was held Tuesday 

 evening, March 14. There was an unusually large attendance, par- 

 ticularly of physicians. Dr. Geerge E. Fell read a paper on "The 

 Histology of Aneurismal Clots," which was listened to with great in- 

 terest. He briefly reviewed the different forms of the disease^ 

 which essentially consists of a pulsating tumor, or expansion of -an 

 artery. The peculiar structure and formation were described and 

 illustrated by drawings and sections. The method found most suc- 

 cessful in examining the abnormal tissues was by the usual process 

 of alcohol hardening, the cutting of sections by a modification of the 

 plan adopted by Dr. Seiler, and the subsequent clearing in carbolic 

 acid, and mounting in Canada balsam. Dr. Fell then detailed the 

 method of differentiating the minute structure by means of various 

 staining fluids, and explained clearly the results of his examination 

 of the structure in question. 



The paper was discussed by Drs. Barrett, Ward, Lewis, Stearns, 

 Howe, Smith, and favorably commented upon. 



Prof. Kellicott, after reading the report of current literature, 

 detailed some of the practicabilities of cutting of thick plate glass 

 for a "section cutter," using simply a rat-tail file and hot iron for the 

 purpose. The results attained demonstrated that a little skill scien- 

 tifically applied would do wonders in glass working. 



Dr. J. W. Ward gave an interesting account of a new micro- 

 spectroscope made from a frog's muscle, and capable of fine work.
