THE MICROSCOPE. 133 



lus. Koch retaliates on his critics by charging them with incapacity, 

 and in this he is warmly supported by those who have been fortunate 

 enough to bring the microzyme within the field of their lenses. We 

 have never gone out on a voyage of discovery for the parasite, and 

 probably, in common with the many who have searched for it in 

 vain, would fail to recognize it when we should see it. Dr. Stieren, 

 in our present number, gives- us a drawing of what he has discovered 

 and claims to be the bacillus. He may be correct, but it would be 

 no disparagement of his ability as a microscopist to doubt the cor- 

 rectness of his picture. It bears a stronger likeness to the fat crys- 

 tals which Schmidt declares deceived even Koch, than it does to the 

 bacillus as figured by W. Watson Cheyne, and a chromo-lithograph 

 of which is before us. We have never seen an unquestionable Koch 

 bacillus, and cannot say which of these pictures is the true one. —

A Magnificent Cabinet. — Dr. Lewis M. Eastman, of Balti- 

 more, President of the Baltimore Microscopical Society, and known 

 throughout the civilized world as a distinguished mounter of micro- 

 scopic objects, possesses the largest cabinet in microscopy in the 

 United States, if not in the world. Not only is his cabinet noted 

 for its great extent, but also for the fineness of the collection. It is 

 very full and complete in the departments of histology, pathology, 

 microscopic botany and fungi, diatomacire algae, mineralogy, etc. 

 His coal preparations are wonderfully fine, showing their vegetable 

 cells in cross and longitudinal section, almost as distinctly as in a 

 freshly mounted vegetable section. His double and simple stained 

 vegetable and animal sections are marvels of neatness, surpassing 

 any that we have heretofore seen. An entire week could easily be 

 spent in looking at his collection of diatoms, alone; and such 

 diatoms! Diatoms from all parts of the earth, selected and arranged 

 slides, which, for cleanliness and beauty of arrangement, would 

 make a diatomaniac wild with joy. We spent an entire afternoon 

 looking at arranged diatoms without exhausting that department. 



Baltimore boasts of two institutions for the visitations of 

 scientists — Johns Hopkins University, the best equipped institution 

 for biological research in this country, and Dr. Eastman's cabinet of 

 microscopic objects — the finest and largest in the world. — Dr. Up 

 de Graff, in The Bistoury.
