276 THE AMERICAN MONTHLY [Sept. 



The above list includes scarcely one-half the varieties 

 I find in a single sample of this deposit ; other strata 

 contain many other species, but I have no time at present 

 to make out a list of them. 



The i8th Annual Meeting of the American Microscopical 



Society. 

 The 18th annual meeting of the society was held in 

 the buildings of the Cornell University at Ithaca, N. Y., 

 August 21-23. The meeting was in every way a very 

 successful and enjoyable one. Thirty-two papers were 

 presented. Of these seven were devoted to botanical, 

 ten to zoological and histological subjects, and fifteen to 

 the microscope or its accessories and the preparation and 

 mounting of microscopical material. The entertainment 

 possible at such a place was made the most of by the 

 members. The magnificent library of the University, 

 collection of botany, zoology and entomology were freely 

 open for inspection. 



WEDNESDAY MORNING. 



The open session was held in McGrraw Hall, Wednes- 

 day morning, August 21, at 10 a. m., with President 

 Gage in the chair. The visiting microscopists were 

 heartily welcomed by Hon. D, F. Van Vleet, of Ithaca, 

 who spoke of the facilities which would be afforded the 

 members for scientific work. Prof. Gage made an ap- 

 propriate response. 



The reading of papers was next taken up, of which 

 space does not permit us to give abstracts. The follow- 

 ing list was presented and discussions followed by mem- 

 bers of the society : 



Some notes on alleged meteoric dust, by Magnus 

 Pflaum, of Pittsburg, Pa. 



Corky outgrowth of roots and theix. connection with
