156 The Microscope. 



The paper discussed the reasons why women teachers were 

 paid inferior salaries to men ; named many openings now ready 

 for women if they were only prepared to fill them ; and dwelt 

 at length upon the intellectual and pecuniary advantages derived 

 from post-graduate work. Women were urged to make more 

 thorough and adequate preparation. There was great need of 

 competent women as superintendents and physicians in our re- 

 formatory, penal, and charitable institutions, and especially 

 should they be found in insane asylums. The facilities for post- 

 graduate study in Michigan University were shown to be ex- 

 ceptionally good. Mrs. Stowell's paper will be published in 

 full. — Inter- Ocean. 



THE BACILLUS OF CHOLERA (Koch). 



Through the kindness of Dr. J. S. Kinyoun, of Centerview, 

 Mo., I have recently received a slide of pure cultivation comma 

 bacillus, the pathogenic cholera bacillus of Koch, and have had 

 opportunities for a close and prolonged examination of the 

 micro-organism in question. I had previously had an oppor- 

 tunity of studying a slide prepared in Dr. Koch's laboratory, 

 under his direct supervision, and I find the two slides appar- 

 ently identical, so far as the bacilli are concerned. The studies 

 were made with a one-sixteenth first-class immersion objective 

 (Bausch and Lomb) and a half-inch eye-piece, giving an ampli- 

 fication of about 3,200 diameters. Candor compels me to say 

 that I can see no difference between the comma bacillus as 

 shown in these slides and bacilli found by me in dust, in water, 

 and in deposits from the atmosphere at various times in St. 

 Louis and elsewhere. Of course I do not pretend to place my 

 limited experience and facilities against those of Dr. Koch and 

 other savants, who declare that the comma bacillus is differ- 

 ent from other organisms having the same general appearance. 

 The standing of Dr. Koch, the completeness of his work in 

 other departments of microscopy, especially his great achieve- 

 ment in tuberculosis, a work that will forever stand as a monu- 

 ment of careful, thorough, honest research, should alone make 

 one very careful in drawing conclusions contrary to his dictum.
