ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 523 



brought to the notice of microscopists, for it contains a number of 

 valuable papers which have hitherto been very difficult of access, owing 

 to their having been published in official Indian reports, or in Indian 

 medical journals ; we may cite the ' Keport on Bladder-worms,' ' The 

 Microscopic Organisms found in the blood of Man and Animals, and 

 their relation to disease,' the memorandum on the Comma-bacillus, and 

 other reports on the agent or agents which produce cholera. 



Cole's Microscopical Preparations. — We are naturally opposed in 

 principle to free advertisements, but Mr. A. C. Cole has done such a large 

 amount of valuable work in the extensive series of microscopical pre- 

 parations that he has from time to time placed at the disposal of micro- 

 scopists, that we cannot but call attention to the fact that though he has 

 been obliged to discontinue the publication of his descriptions of prepara- 

 tions he still continues to issue the preparations themselves in the same 

 condition of excellence as before. Any support given to Mr. Cole will 

 be well directed in the interest of microscopy. 



Enock's Insect Slides. — While Mr. F. Enock works in a more limited 

 sphere than Mr. Cole his slides are, as is well known, quite unique of 

 their kind as models of mounting, and Mr. Enock deserves a large 

 measure of appreciation at the hands of microscopists. Mr. Enock 

 supplies with his slides a description with figures illustrating the chief 

 points, which, as we have before noticed in these pages, largely increases 

 their value.

[" If physicians would only try the experiment for a few times of consulting 

 the Microscope in their doubtful cases of urinary disorders, we feel assured 

 that they would never again attempt to treat these disorders without a com- 

 petent microscopical examination. We feel further assured that when one 

 becomes acquainted with the value of the Microscope in this particular 

 direction, he would be impelled to apply the same instrument and methods 

 to the diagnosis of other troubles. He who fails to do so deliberately throws 

 away the most powerful aid to diagnosis yet discovered."]
