THE MICROSCOPE. 149 



in this country. On examining the crop, which was greatly dis- 

 tended, of one fowl, numerous specks were observed distributed 

 over the whole surface. These proved to be watery cysts of a new 

 species of spirillum (?), the male differing from any other nematoid 

 known to the author in having on the terminal point of its caudal 

 appendage a bulbous body covered with short spines. The above- 

 mentioned parasites undoubtedly cause disease and death among 

 domestic fowls. 



In histology a valuable paper was presented by Dr. M. L. Hol- 

 brook on "The Termination of the Nerves in the Kidney "; also one 

 by Dr. G. E. Fell on "A Hitherto Unnoticed Peculiarity of the 

 Human Spermatozoon." Dr. A. M. Bleile and Adolph Friel re- 

 ported a continuation of their investigations as to the effects of 

 division of the vagi on the muscles of the heart. 



Dr. V. S. Clevinger reviewed the knowledge and recent pro- 

 gress concerning the physiology and patholology of the brain. "The 

 study of brain and nerve tissue, as well as other biological investiga- 

 tions, is destined to reveal a great many phenomena, to result in 

 saving of health and mentality to multitudes unborn. The thought 

 of the ignorant is that scientists do not have ultimate knowledge; 

 that they do not know the pathology of every form of insanity or 

 disease in general. This should be no reason why we should not 

 encourage these researches in every way possible, for year after year 

 the grandest discoveries in these matters are being made by toil- 

 some steps, and there is actually no predicting the benefits to 

 accrue." 



The important art of photo-micrography was treated by W. H. 

 Walmsley in a paper giving the latest improvements and discov- 

 eries. 



Dr. S. Huson gave a general review of our knowledge of the 

 yeast plant. In the course of his remarks he said he had found it 

 one of the most reliable tests for diabetic urine. The test is made 

 by setting aside an uncorked bottle of the suspected urine for a few 

 days. The presence of abundance of the fungus was a sure indica- 

 tion of the presence of sugar. 



Papers of a general interest were received from Prof. Sarah F. 



Whiting on College Microscopical Societies; Prof. S. H. Gage on 



Cataloguing, Labeling and Storing Microscopical Preparations; and 



Prof. J. W. Mansfield on Division of Labor among Microscopists.
