toward the effective restoration of fossils, and to these reference 

 has been made. A series of life-size restorations of the Eurypterida 

 of the genera Pterygotus, Eurypterus, Eusarcus and Stylonurus, 

 have been prepared, effectively colored, framed and set up in the 

 Museum. The reproduction of Pterygotus, a New York species, 

 is upwards of 9 feet in length, a statement which may con- 

 vey some conception of the enormous size attained by these great 

 arthropods of the shallow waters of the Silurian sea. Doctor 

 Ruedemann has also very successfully rendered a series of recon- 

 structions of the cephalopods, showing the interior structure as well 

 as the complete form of the exterior. This series includes the 

 genera Manticoceras, Gyroceras, Endoceras, Orthoceras, Piloceras, 

 Trochoceras and Gonioceras, all on sufficiently large scale to bring 

 out the structural details, which are not always clearly preserved in 

 the fossils themselves. 



In the face of the pressure of Museum work it has not been 

 possible during the past year to accomplish any field work in paleon- 

 tology or to carry forward in the office any extensive researches 

 in this subject. 



For a number of years past the paleontologist has made reference 

 in these reports to the development of the New York fossil faunas 

 and their containing formations in lower Canada, specially in the 

 region of the Gaspe peninsula. During the summer of 191 3 the 

 twelfth meeting of the International Geological Congress convened 

 in Toronto, and among the geological excursions that were prepared 

 in connection with that meeting was one into the Maritime Provinces 

 including the Gaspe peninsula. At the request of the Canadian 

 authorities, the paleontologist prepared a guide for the part 

 of this excursion embracing the Gaspe peninsula and a portion 

 of northern New Brunswick, and was privileged to act as guide 

 over part of the course. This inviting excursion was participated 

 in by about seventy geologists from various parts of the world, 

 among them being the directors of the Geological Surveys of Great 

 Britain and of France, as well as distinguished workers in this field 

 from all the countries of Europe, from Indo-China, China, Japan, 

 South Africa and the isles of the sea. Inasmuch as this field has 

 been so fully exploited in the reports of the New York Geological 

 Survey, it seems altogether appropriate now to present here a sum- 

 mary opinion of its geology by the director of the ' Geological 

 Survey of France, M. Pierre Termier, recently published in the 

 Proceedings of the Academie des Sciences. For these very ex-
