1892.] MICROSCOFICAL JOURNAL. 199 



Meetings are held the last Tuesday evening in each month. 

 The club has the use of one of the botanical laboratories in Ne- 

 braska Hall at the University, and has put in the proper lamps 

 and fixtures so that a large number of instruments may be used at 

 night. The club has the use of the microscopes and accessories 

 of the Department of Botany and has access to the library of the 

 department, which contains the principle microscopical maga- 

 zines. The members usually bring their instruments with them 

 to the meetings and exhibit slides and other objects of interest at 

 the close of the meetings. 



June 28. — Dr. Billings gave a lecture on Bacteriology, and at 

 its conclusion, in answer to questions, spoke on methods of mak- 

 ing permanent mounts of bacteria and of decolorizing animal tis- 

 sues in sections. Mr. Webber, of St. Louis, gave some observa- 

 tions on the structure of the capsule in Yucca, and, answering 

 questions, suggested a new manner of fixing celloidin sections. 

 Among the slides exhibited were several by A. F. Woods illus- 

 trating some new methods with glycerine jelly.

May <5, i8g2. — The annual exhibition was given at the resi- 

 dence of J. C. Gregory. Eleven microscopes were used in the 

 exhibition. These were arranged on tables scattered through 

 several rooms, occasioning frequent tours from one to another to 

 witness the changes of the subjects. While all were of interest, 

 perhaps the most fascinating was an exhibition of the circulation 

 of blood in a live frog's foot, given by Dr. G. F. Blauvelt, who 

 gave a number of exhibitions in the line of histology. 



Mr. Gregory exhibited some mineral crystals, shown by re- 

 flected light, and Miss Gregory's line was vegetable sections ex- 

 hibited by polarized light. Mr. F. G. Provost's selections for 

 the evening were botanical, and Mrs. Provost's were entomologi- 

 cal, shown with condensed light. Prof L Lawton sliowed some 

 interesting specimens in entomology. Dr. Coltrin embraced en- 

 tomological and botanical subjects in his list of exhibits, shown 

 by transmitted light. ]Miss Whittaker's line of exhibits was botany 

 and entomology ; JSIiss Stillwell's was entomology, and Miss
