THE MICROSCOPE. 221 



Chicago, 111., Oct. 29, 1883. 

 Chas. H. Stowell, M. D.: 



Dear Sir. — At the first regular meeting for the season, of the 

 State Microscopical Society of Illinois, Dr. H. A. Johnson was an- 

 nounced to read a paper on "Some organic remains found in the 

 boulder clay underlying Chicago," he being absent however, Mr. 

 Fellows showed some specimens of the organisms found by Dr. 

 Johnson. Dr. H. J. Detmers referring to an article by A. Y. Moore 

 in the June number of the Microscope, on the resolution of 

 amphipleura pellucida with mirror central "stated that he thought 

 the explanation therein was entirely incorrect, his explanation being 

 as follows: The light from the mirror central passed through the 

 slide, etc., some of the light being totally reflected from the convex 

 surface of the immersion fluid, on to the diatom thereby illumin- 

 ating it by oblique light from above giving often a dark field 

 illumination and resolving the diatom beautifully. The doctor 

 stated that he had written to Mr. Tolles on the subject and that he, 

 (Mr. Tolles) had said that this theory was correct. 



Mr. W. H. Bullock showed a new nose piece which has very 

 superior advantages over other adapters, especially as it will not 

 come off when using collar adjustment. 



A resolution was passed offering copies of the lens, complete 

 for $3 per set. 



Yours truly, 



Wm. Hoskins, Secretary. 



Dr. Detmers desired me to state that he would send you for 

 publication a full description of his theory, etc. 



Recall at night not only your business transactions, but what 

 you have said of those of whom you have spoken during the day 

 and weigh in the balance of conscience what you have uttered. If 

 you have done full justice in all your remarks, it is well. If you 

 have not, then seek the opportunity to make amends, and carefully 

 avoid a repetition of the wrong. 



Life is the Great Antiseptic. — "Life and putrefaction are 

 not correlative, but antagonistic; and in proportion as the surgeon 

 utilizes and economizes the attributes of life, he will find himself in- 

 dependent of these changes which are inherent to decaying organic 

 matter whether it be in bagging wounds or boggy lands. Life is 

 the great antiseptic."
