ture, will preside over it, and Lord Jersey and 

 Mr. Gill will be among its members. 



It is announced that the Proceedings of the 

 Royal Society is henceforth to be brought out 

 in a new form. It will assume roj^al octavo 

 size, and be printed in larger type than is the 

 case at present. Also two series will appear 

 in future, one embracing mathematical and 

 physical papers, the other biological papers, 

 and each part will be on sale to the public 

 separately. 



At a meeting of the Zoological Society of 

 London on April 18, Dr. W. J. Holland, F.Z.S., 

 director of the Carnegie Museum and Insti- 

 tute, Pittsburg, U.S.A., gave an account, il- 

 lustrated by stereopticon slides, of the dis- 

 covery of the skeleton of Diplodocus carnegii 

 Hatcher, a reproduction of which he was in- 

 stalling in the Gallery of Reptiles at the 

 British Museum (Natural History), South 

 Kensington. After paying tribute to the gen- 

 erosity of Mr. Andrew Carnegie, who had sup- 

 plied the funds necessary for the extensive 

 explorations which were being carried on by 

 the Carnegie Institute, under the direction of 

 the speaker, he went on to speak of the geology 

 of Wyoming and of the immediate locality, 

 where the specimen was obtained. He in- 

 cidentally described the methods employed by 

 American collectors to secure vertebrate fossils 

 in fine condition. He then discussed the 

 osteology of Diplodocus, briefly pointing out 

 some of the more interesting structural fea- 

 tures of the skeleton, and in this connection 

 animadverted upon certain so-called ' restora- 

 tions ' made public in popular magazines and 

 emanating from artists whose artistic ability 

 was quite in excess of their scientific knowl- 

 edge. Dr. Holland concluded his account by 

 exhibiting in rapid succession pictures of a 

 few of the more remarkable skeletons which 

 had been recovered by the paleontological staff 

 of the Carnegie Museum from various local- 

 ities in the region of the Rocky Mountains. 

 At the same meeting Dr. Smith Woodward, 

 F.R.S., read a paper on a unique specimen of 

 Cetiosanrus leedsi, a Sauropodous Dinosaur 

 from the Oxford Clay of Peterborough. He 

 described the fore and hind limbs and the tail. 



and confirmed the observation of the late Pro- 

 fessor O. C. Marsh, that Citiosaurus was one 

 of the more generalized Sauropoda. 



Mr. Edwin C. Eckel, of the United States 

 Geological Survey has just completed a report 

 on the cement materials and industry of the 

 United States. In view of the phenomenally 

 rapid growth of the cement industry within 

 recent years, the publication of this report is 

 exceptionally timely. In collecting data for 

 it, Mr. Eckel visited every district in which 

 cement is produced and examined nearly 

 every plant in operation. Information re- 

 lating to undeveloped deposits of cement ma- 

 terials was obtained by personal examination 

 and from the published and unpublished work 

 of other geologists. The discussion is in four 

 parts, the first relating to the materials and 

 manufacture of Portland cement, the second 

 to Portland cement resources of the United 

 States, the third to natural cement resources 

 of the United States, and the fourth to the 

 materials and manufacture of Puzzolan or 

 slag cement. Few people realize how mani- 

 fold are the uses of cement. In its impor- 

 tance to our present civilization it is sur- 

 passed among mineral products only by iron, 

 coal and oil. In rate of increase in annual 

 production during the last decade even these 

 three products can not be compared with it. 

 In 1890 the total production of Portland ce- 

 ment in the United States was 335,500 barrels, 

 valued at $439,050; in 1903 it exceeded 22,- 

 000,000 barrels, while the value was over 

 $27,000,000. 



UNIVERSITY AND EDUCATIONAL NEWS. 

 TftE proposed affiliation or alliance of the 

 Massachusetts Institute of Technology with 

 Harvard University was approved at a meeting 

 of the corporation of the institute on June 9. 

 Thirty-two of the forty-seven members of the 

 corporation were present, and by a vote of 20 

 to 12 it was agreed to accept the terms of the 

 agreement recently drawn up by the com- 

 mittee of the two institutions. Before the 

 agreement can become effective the corpora- 

 tion and overseers of Harvard University 

 must take action and several legal questions 

 must be passed upon by the courts. It will
