materials. Upon this subject I may in future give you some par- 

 ticulars. 



Let us remember that photomicrography, and the various re- 

 sults, in the form of prints and lantern slides, are always wel- 

 come themes that may be demonstrated at the meetings, and that 

 would be received with pleasure by the members generally. I 

 also request that those engaged in the lines of histology, patho- 

 logy, and bacteriology bring before us from time to time, as Dr. 

 Heitzmann proposes to do at the next meeting, notice of their 

 work in papers on these subjects, which we guarantee will be 

 received with deep attention. 



I will not burden you with further suggestions at present. If 

 I shall accomplish nothing more, in the future I will endeavor to 

 infuse enthusiasm in some of our friends who are able to pre- 

 sent their good works before you. If each of us will at least 

 add a little toward the general interest, much usefulness and en- 

 joyment will doubtless result, to the benefit of the Society, whose 

 prosperity we all have at heart.
