OV)jects for the Microscope," and illustrated it by the actual

 under the microscope. A number of instruments were loaned 

 to him for the purpose.

Novanber 14. — The meeting was one of much interest and 

 there was a good attendance, several visitors being present. Dr. 

 Robert Reyburn, with the aid of the stereopticon and screen, 

 exhibited a large number of micro-photograpbs, chiefly histo- 

 logical, many of them being his own work. The comparative 

 merits of wet and dry plates in this class ot work were seen in 

 the images on the screen, those made on wet plates being by far 

 the clearest and sharpest. One of these slides representing the 

 formation of pus, gave rise to an inttresting discussion as to 

 ■whether such formation results from the proliferation of the nu- 

 clei of the epithelial cells, or arises from a lower layer. 



Dr. J. M. Lamb followed with a paper on bone formation, 

 and some methods of preparing it for class demonstration. He 

 exhibited finely prepared specimens of full sized bones sawn 

 into thin sections, beautifully whitened and displayed. Dr. J. 

 H. Rindldub was elected a member of the Society.

We have before us a very elaborate hand-book of me- 

 thods for tlie preparation, staining, and microscopical investi- 

 gation of vegetable structures. Dr. Zimmermann, who is a pro- 

 fessor in the University of Tubingen, published this volume in 

 1891-2. Dr. Ellis has made important additions, in the Eng- 

 lish edition, in the way of notes and tables as well as in the 

 text itself. He has deemed the translation necessary because, 

 as he says, but lew English speaking, elementary students read 

 German readily. Assuming this dejjlorable fact to be true, we 

 must incidentally interject a protest against the popular edu- 

 cation of the day which permits such to be the case.
