The regular meeting of the Academy of Natural Science 

 was held on Friday evening last. Dr. Garlick, Vice Presi- 

 dent in the chair. The minutes of the previous meeting 

 were read and approved. 



Dr. Garlick presented a collection of fossils believed to 

 be from the eastern slope of the Rocky Mountains. They 

 were referred to a committee consisting of Col. Whittlesey, 

 J. H. Klippart and Prof. Brainerd. 



Col. Whittlesey exhibited a series of Charts of Sections 

 of the Drift Formation, from the North and South shores 

 of Lake Erie to the Lake of the Woods, embracing a great 

 extent of Ohio, Canada West and Michigan, the shores of 

 Lakes Huron, Michigan and Superior. 



Underlying the Drift was shown that peculiar fresh 

 water deposit, called, in the neighborhood of Cleveland, 

 the blue clay, but which is in reality a very fine sandy 

 marl, containing vegetable matter. The Colonel gave a 

 very interesting description of these rocks and their pecu- 

 liarities of structure and position, and exhibited a large 

 root and a portion of a stem of a tree found imbedded in 

 the latter deposit. The vegetable remains found in this 

 stratum are not petrified, and but slightly decayed. 



Mr. E. Palmer exhibited a number of insects and crusta- 

 ceans from South America, among them some interesting 

 and novel specimens. 



Dr. Garlick again exhibited microscopic views of the 

 anatomical structure of the embryo Salmo Fontinalis.
