tributed among Swedish engineers who desire 

 to visit the Panama-Pacific Exposition in San 

 Francisco in 1915. 



The fiftieth meeting of the New England 

 Association of Chemistry Teachers will be 

 held in Boston on Saturday, April 25, 1914. 

 The morning session will be devoted to the 

 past, present and future of the association. 

 Past presidents will speak, ,"nd the history of 

 the association will be read. A complimen- 

 tary luncheon will follow. It is hoped that 

 the afternoon session will include a moving 

 picture exhibition of chemical industries. In 

 the evening there will be a reception and col- 

 lation, followed by speaking, at the Copley 

 Plaza. 



The twenty-fifth session of the Biological 

 Laboratory of the Brooklyn Institute of Arts 

 and Sciences, located at Cold Spring Harbor, 

 Long Island, will be held from June to Septem- 

 ber. The regular class work will begin Wed- 

 nesday, July first, and will continue for six 

 weeks, to August 12. The instruction offered 

 includes a course in field zoology by Dr. H. E. 

 Walter, of Brown University, assisted by Dr. 

 S. I. Kornhauser ; in bird study by Mrs. H. E. 

 Walter; in comparative anatomy by Professor 

 H. S. Pratt, of Haverford, and Dr. D. D. Whit- 

 ney, of Wesleyan University ; in animal bionom- 

 ics and evolution by Dr. C. B. Davenport ; cryp- 

 ^togamie botany by Professor H. H. York, of 

 Brown University, and Dr. W. E. Maneval; 

 systematic and field botany by Professor John 

 W. Harshberger, of the University of Penn- 

 sylvania. Opportunities are also offered for 

 investigation in zoology and botany. A train- 

 ing course for field workers in eugenics is 

 given under the direction of Dr. C. B. Daven- 

 port and Mr. H. H. Laughlin. The complete 

 announcement may be got by addressing the

There are now being assembled in the 

 United States National Museum, the bones of 

 a very small three-horned dinosaur which is 

 being made the type of a new species. This di- 

 minutive dinosaur, when completely as- 

 sembled, will measure about six feet in length 

 and stand only about three feet high. Its head 



is twenty-two inches long. When its bones 

 are compared with those of the larger mem- 

 bers of this extraordinary family of reptiles, 

 it will be seen that this specimen is less than 

 one fourth of their size. In the National Mu- 

 seum are several skulls of one of the large 

 horned dinosaurs, Triceratops, which measure 

 from six to eight feet, and in one case, nine 

 feet. The group to which this new member 

 belongs is called the Ceratopsia, from the horns 

 which adorn their heads; two above the eyes 

 and one on the end of the nose. Unlike the 

 others, this species has small and not promi- 

 nent horns over the eyes, while the nasal horn 

 is an outgrowth of the nasal bone and not an 

 additional growth, as is the case with the 

 others. Another peculiarity is that this horn 

 is split lengthwise in such a manner that one 

 side has the appearance of having slipped by 

 the other. Its jaws are like those of a turtle, 

 there being no front teeth but a sharp curved 

 beak. Farther back in the jaws, however, are 

 very finely sculptured cutting teeth, which 

 show the animal to have been herbivorous. 

 Like the other members of this group, it has 

 a deep collar known as a frill, but in this spe- 

 cies it has an open space on either side of the 

 neck. The frill was covered with horn and 

 formed a defensive armor for the protection 

 of the neck. This particular specimen was 

 found with the foot and tail articulated, 

 which makes it especially interesting as being 

 the first complete and connected specimen ever 

 obtained. The foot has four toes, the first with 

 two bones, the second with three, the fourth 

 with five, while only a trace of the fifth toe 

 remains, tending to show the loss of that mem- 

 ber through disuse, as is the case with the 

 horse. Parts of the other feet are also in this 

 collection, as well as nearly all the bones of 

 one individual. In the whole specimen there 

 are but few bones and parts which will have 

 to be restored. Considering that the first 

 specimens of this family were discovered some 

 forty years ago, it is curious that this small 

 individual is the most complete one that has 

 been found. These fossils were found by Mr. 

 Charles W. Gilmore during the summer of 

 1913, while he was working for the Geological
