190 The Microscope, 



Editor of The Microscope :— 



In a recent chapter of " Amateui's " notes, we observe that he 

 ■states that " If the physician wishes to make more delicate in- 

 vestigations with higher powers, or to enter even a little way into 

 Bacteriology, he must seek a stand that shall be more complete 

 in its sub-stage arrangements than is the Acme No. 4, as a sub- 

 stage condenser cannot be added to it, and this accessory is now 

 essential for even the least advanced worker." We hope you 

 will allow us, to correct this statement, as we are constantly sup- 

 plying these microscopes for bacteriological work, with an ad- 

 justable sub-stage condenser, rendering it admirably adapted for 

 use with even the very highest power oil-immersion lenses. The 

 workmanship, and delicacy of action of the adjustments being 

 as perfect in this instrument as in the more expensive instru- 

 ments, we highly recommend it for professional work with even 

 the very highest powers, although undoubtedly a movable sub- 

 :stage affords an additional convenience or refinement for high- 

 power work. Yours very truly,

In Prof Seaman's article in the May number he mentions that 

 Ann Arbor uses largely American microscopes, etc. This state- 

 ment is both right and wrong. As everyone knows, the Univer- 

 sity of Michigan is without doubt a great institution, but its 

 scientific departments, especially microscopy, are nothing to what 

 they should be. Why ? Because they are handicapped through 

 want of means to an extent which is not and cannot be realized 

 by anyone outside of the University. It tries with might and 

 main, but cannot do the work it should, for most of the students 

 are not Avealthy, the number of good microscopes is very small, 

 and the number of instructors inadequate in comparison to the 

 students and in quality, for no good men can give their time and 

 knowledge for the paltry sum paid, it being in many cases only 

 sufficient for board and rooms with very little over. The micro- 

 scopes are mostly foreign makes, as can be easily proved by refer- 

 ence to the catalogue : Zeiss, Beck, Leitz and a few by Bausch 

 and Lomb; the majority of the latter I believe are the poorest 

 stands and oldest patterns, not, let it be understood, through any 

 fault of the firm, but because the University had such poor
