4. JOURNALS. 
The student should consult the numerous papers by Prof. Marsh 
in The American Fournal of Science; and by Prof. Cope in The 
American Naturalist. Many of Prof. Marsh’s papers have also 
appeared in 7he Geological Magazine and in Nature. The two latter 
journals contain many other valuable papers (and reviews of Mono- 
graphs, etc.), too numerous to be separately mentioned. Some are 
referred to in the text. The Quarterly Fournal of the Geological 
Society contains many papers on Extinct Animals. See also papers 
in Natural Science and Knowledge.
