a ring cemented to a slide, with a thin cover containing the nutritive 

 fluid and spores upon its under surface, the interior being protected 

 from outside influences by a few drops of oil around the edge. The 

 growth of the fungus was carefully watched, and, in spite of some minor 

 differences, the author believes this fungus is a Ulucor. 



— Index Medicus is the title of a new monthly periodical which is to 

 appear in January, 1879. It is to be a classified record of the current 

 medical literature throughout the world, compiled under the super- 

 vision of Dr. J. S. Billings, Surgeon, U. S. A., and Dr. Robert Fletcher, 

 M. R. C. S. F. Leypoldt, 37 Park Row, New York, is the publisher. A 

 work of this kind will be of great value to students of medicine and 

 deserves their hearty support. 



— Science News is a fortnightly magazine, of 16 pages, octavo size, 

 published by S. E. Cassino, Salem, Mass., for $2.00 per year. Ernest 

 Ingersoll and Wm. C. Wyckoff are the editors. The first number was 

 issued November i, 1878. It aims to publish all scientific news prompt- 

 ly, and furnish notes of current literature. The first three numbers have 

 reached us, and the matter is excellent. It seems to be just the kind of 

 a journal for a large class of readers, and we believe it is to become a 

 valuable periodidal. 



— Mr. S, H. Gage writes : " Among some eels received at the anatom- 

 ical department of Cornell University, in March 1874, there was a 

 female with the ovaries very large and crowded with ova, averaging 

 about 23 mm. in diameter. The nucleous and viteline membrane were 

 both very plain. In October of the present year, a very large eel was 

 received from Cayuga Lake. In this the ovaries were likewise con- 

 spicuous, but upon examination, their size seemed to be mostly due to 

 an accumulation of fat ; but ova were also found in great abundance ; 

 their average size being only .092 mm. The nucleous and viteline 

 membrane were very evident."

 The popular interest in microscopy is growing rapidly in this coun- 

 try. We are pleased to notice the formation of The MICROSCOPICAL 

 Society, OF Camden, N.J. We trust that the energy displayed by 

 the members thus far will not be allowed to grow less in the future.
