5. Fhistocene Geology of Western JVew York ; by H. L. Fair- 

 child. Report of progress for 1900. 20th Ann. Kept. N. Y. 

 State Geologist, pp. 105-139 ; pis. 9-41. — Professor Fairchild has 

 made a special study of the Iroquois shore line between Rich- 

 land and Watertown, and finds that the warping of the Ontario 

 basin has occurred mostly since the extinction of glacial Lake 

 Iroquois, and that "the rate of deformation has been much 

 greater than the present rate." The territory between Syracuse 

 and Oneida was studied with reference to the higher channels cut 

 by overflow of glacial waters.

7. On Yertehrates of the Mid- Cretaceous of the Northv^est

 begun by the volume on the Cypress Hills species contributed by 

 the late E. D. Cope, in 1891. Professor Osborn contributes the 

 first paper on the Distinctive features of the mid-cretaceous fauna^ 

 in which he reaches the conclusion " that the Belly River fauna is 

 more ancient in character both as to the older types of aninicds 

 which it contains and as to the stages of evolution among ani- 

 mals which ewe also represented in the Laramie.'''' (p. 21.) 



L. M. Lambe contributes the second descriptive paper : — New 

 genera and species from, the Belly Biver series (mid-cretaceous).^

 new. H. s. w. 



8. Qiieneau on Size of Grain in Igneous Bochs ;* by Alfred ^^ 

 C. Laxe. (Communicated.) — In this paper (a thesis for the mas- 

 ter's degree) the author takes up the theory of grain proposed by 

 myself in part 1 of vol. vi of the reports of the Geological Sur- 

 vey of Michigan, and successfully applies the same to the " Pali- 

 sade " intrusive near New York, and, with very interesting re-
