say that the above granite is as distinct from the West Country 

 granites as any two species can be. Now for the first time we learn 

 that the Peterhead granite was consolidated in the presence of 

 compressed hydrogen, just as we know that the Dartmoor rock 

 crystallized out of fluids charged with salts. The conditions 

 were different and the minute results are different — very. Those 

 intersecting planes of fracture are significant enough. The Rubislaw 

 granite was consolidated ; then cracked and recemented ; then 

 cracked again and recemented ; and the cements varied in the two 

 cases. In the one, the cementing silica was charged with gas, iu 

 the other not apparently so. These facts are patent to anyone 

 who will take adequate pains to see them. The explanations must 

 be left to experts. A. E. Hunt.

 BoKN July 28, 1840. Died Apeil 12, 1897. 



It is with deep regret that we record the death of Professor 

 E. D. Cope, the eminent palaeontologist and comparative anatomist, 

 late of 2100, Pine Street, Philadelphia, Pa., U.S.A. E. D. Cope, 

 who was born at Philadelphia, July 28, 1840, studied in the 

 University of Pennsylvania and worked at anatomy in Europe 

 (in 1863-4). For the three succeeding years (1864-7) he filled 

 the Chair of Professor of Natural Science in Haverford College, 

 Philadelphia, and was for some years Curator and Corresponding 

 Secretary of the Academy of Natural Sciences in that city. At the 

 time of his death he held the Chair of Geology and Palaeontology 

 in the University of Pennsylvania. From 1871-7, he carried on 

 explorations in the Cretaceous strata of Kansas ; the Eocene of 

 Wyomino-; the Tertiary beds of Colorado. He also served on the 

 U.S. Geological Survey in 1874 in New Mexico; in North Montana 

 in 1875 ; in Oregon and Texas in 1877. 



He has accumulated a collection of over 1000 species of extinct 

 Vertebrata, and has made known at least 600 species new to science. 

 Professor Cope was a voluminous writer, and his papers are published 

 in the Proceedings of the scientific Societies of Philadelphia, and 

 in the Keports of the U.S. Geological Survey of the Territories 

 under Dr. F. Y. Hayden and Captain Wheeler. Professor Cope was 

 an advanced Evolutionist, and his contributions on this subject 

 have been very numerous. He was the senior Editor of the 

 "American Naturalist," a monthly journal which contains many 

 of his original essays. He was a Foreign Correspondent of the 

 Zoological and Geological Societies of London, and received the 

 Bigsby Gold Medal in 1879 from the latter Society, in recognition 

 of the genius and skill with which he had enriched the sciences of 

 Comparative Anatomy and Palseontology, and the immense and 

 varied work which he had achieved among the fossil Vertebrata.
