APPENDIX. 263 



4. Journals. 



The student should consult the numerous papers by Prof. Marsh 

 in The American Journal of Science ; and by Prof. Cope in T/te 

 American Naturalist. Many of Prof. Marsh's papers have also 

 appeared in The 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 Journal of the Geological 

 Society contains many papers on Extinct Animals. See also papers 

 in Natural Science and Knowledge.
