290 PROCEEDINGS OF THE ACADEMY OF 



Hunt's dissertation on the Preparation and preservation of 

 Tissues; Mr. Joseph Zentmayer's discourse upon Erectors and 

 a new Erecting prism; Dr Jas. Tyson's article on Urinary 

 microscopy, and his interesting oral communication upon Practical 

 Histology in Germany; and Dr. Jos. G. Richardson's papers on 

 Certain Human Parasitic Fungi, and their relations to disease, 

 and upon a new method of preserving Tumors and some urinary 

 deposits during transportation. 



Discussions upon the various subjects thus brought under the 

 consideration of the members, have been remarkable for their un- 

 usually practical and useful character; indeed, so eminent have 

 they appeared in this respect, that reports of our proceedings have 

 always been warmly welcomed by the Editors of The Philadelphia 

 Medical Times, in whose interesting columns they, as well as 

 several of the papers read before the Section, have from time to 

 time been published. 



All of which is respectfully submitted, 



Jos. G. Richardson, Recorder.
