136 The Ottawa Naturalist. [August 



The earliest paper which appeared from the pen of Prof. 

 Marsh related to the minerals of Nova Scotia. In writing of 

 Prof Marsh's work, Dr. Charles E. Beecher says : 



" His three mineralogical papers, published between 1861 

 "and 1867, show the results of considerable labour and careful 

 " investigation. They treat of the gold of Nova Scotia, a Zeolite 

 " mineral from the .'^ame region and a catalogue of the Mineral 

 " Localities of the Maritime Provinces of Canada." 



The following papers specially relating to Canada are here 



extracted from the " Bibliography " prepared by Dr. Beecher 



, and kindly communicated to me : 



1861 '' The Gold of Nova Scotia." Amer. Journal of .Science (2) vol 32 pp- 

 395-4CO. 



1862 " On the Saurian Vertebr.t from Nova '^icotia " Ibid. vol. 43 p. 278. 



" Description of the Remains of a New Enaliosaurian (Eosannn Acadianiis)- 

 from the Coal Formation of Nova Scotia. Ibid. vol. 34, pp. 1-16, pis. I. -II. 



1863 " Cataloi;ue of Mineral Localities in New Brunswick, Nova Scotia and New- 

 foundland. Ibid. vol. 35, pp. 210-218. 



1S67 " Contributions to the Mineralogy of Nova Scotia." Ibid. vol. 44, pp. 362- 

 367. No. I. Ledereiite identical with Gmelinite. 



Prof Marsh was one of the leading contributors to the 

 American Journal of Science and his writings certainly did 

 much to add zest and interest to that publication. 



His genial and courteous manner as well as characteristic 

 good nature won for him a vast concourse of friends and ad- 

 mirers on both sides of the Atlantic. We shall long miss his 

 beaming countenance and striking individualit}^ 



The " Bibliography " of Prof O. C. Marsh as prepared by 

 Dr. Beecher for the American Journal of Science, 4th Series, 

 Vol VH, pp. 420-428 is most complete and shows clearly what a 

 master mind the subject of this brief sketch possessed. I shall 

 close with words from Dr. Beecher's pen. (loc. cit. p. 419.) 



" In closing the outline of the discoveries made by this 

 '■ investigator one cannot help being impressed with their signal 

 ■'• brilliancy, their great number and especially by their unique 

 " importance in the field of organic evolution. Were all other 

 " evidence lost or wanting the law of evolution would still have 

 " a firm foundation in incontrovertible facts. The study of 

 " variation and Embryology in recent animals gives hints as to 

 " the truth, but Paleontology alone can give the facts of 

 de-scent." H. M. AMI.
