Society on .January 9, a remarkable series of 

 motion pictures made last summer at Bar 

 Harbor. An explanation of the film was 

 given by Mr. Roy W. Miner. Through the 

 aid of the most improved apparatus and a 

 carefully developed technique, Mr. Fabbri 

 has succeeded in reproducing on the screen 

 on a greatly magnified scale many small and 

 microscopic animals. Various species of 

 Protozoa, including the Amoeba, and many 

 small Crustacea like Cyclops, Evadne, Pro- 

 don, and Caprella, were among the forms 

 shown. The presentation of the last was 

 especially interesting, as not only was the 

 entire animal shown, but also, by further 

 enlargement, details of the head and internal 

 structure, and the circulation of the blood. 

 The beating of the heart of an embryo fish 

 within the egg was brought out especially 

 well. The fresh-water Hydra of stagnant 

 pools, which is only about one thirty-second 

 of an inch in length, was magnified upon the 

 screen about six thousand diameters; certain 

 species of the most delicate of marine hy- 

 droids were magnified to a like scale. Mr. 

 Fabbri 's work opens new vistas to the teach- 

 ers of zoology who can introduce such 

 pictures in their classes, and will be of great 

 value to those who are engaged in research 

 on the anatomy and habits of such minute 

 forms. 



Mr. N. C. Xelson returned late in De- 

 cember from a field trip which included a 

 systematic survey of the glazed pottery 

 area of the Southwest, and also an examina- 

 tion of caves and rock shelters in Kentucky. 

 In the Southwest the territory reconnoitered 

 comprised a broad belt from Aztec to Al- 

 buquerque on the Rio Grande, and thence 

 southwest to St. Johns and Springerville in 

 Arizona. During this journey, which in- 

 volved traveling by wagon, in the saddle, 

 and on foot, over more than two thousand 

 miles, and occupied about four months, 

 about four hundred ruins were examined and 

 the more important were roughly mapped, 

 described, and photographed. Wherever ash 

 heaps occurred, stops were made to obtain 

 the stratigraphy of the deposit. 



In Kentucky examination was ma<ie of a 

 series of caves and rock shelters along the 

 Kentucky River, and of a larger series along 

 Green River near Mammoth Cave. Several 

 sites were tried out by excavation. Few of 

 these yielded results of importance, save a 



small rock shelter opposite Boardcut Island, 

 and Mammoth Cave itself. In the entrance 

 to the latter was found a partly buried floor 

 deposit of refuse belonging to a hunting 

 period of culture antedating the introduc- 

 tion of fine polished stone implements and 

 pottery, while in the former were found 

 traces of refuse and a stone cist burial con- 

 taining fragments of pottery, all clearly 

 belonging to a relatively late period of In- 

 dian occupancy of the middle Mississippi 

 region. 



The opening session of the sixty-ninth 

 meeting of the American Association for the 

 Advancement of Science was held in the 

 auditorium of the American Museum of 

 Natural History on the evening of Decem- 

 ber 26. The retiring president. Dr. William 

 Wallace Campbell, director of Lick Obser- 

 vatory, gave an address, "The Nebulae." 

 Following the address, the Honorary Com- 

 mittee which had been appointed by Henry 

 Fairfield Osborn, president of the American 

 Museum, entertained the visiting scientists 

 at a reception in the new hall of the age of 

 man. Mr. Charles R. Knight 's mural paint- 

 ing, "The Age of Reindeer and Mammoths," 

 was unveiled at this time. The orchestral 

 program, under direction of Nahan Franko, 

 included the whole range of nature music 

 from Handel to Strauss. 



At a recent jneeting of the trustees of the 

 American Museum a special grant was voted 

 to the 312 officers and employees of the in- 

 stitution, in view of increased demands made 

 upon them and in consideration of the ad- 

 vanced cost of living. The grant, which 

 equaled ten per cent of the salaries of 1916, 

 was largely provided through personal sub- 

 scriptions by the trustees. 



Mr. Harrington Moore has been ap- 

 pointed associate curator in the department 

 of woods and forestry. Mr. Moore is a grad- 

 uate of the School of Forestry, Yale Uni- 

 versity. In 1908-1909 he studied represen- 

 tative forest regions in Germany, France, 

 India, Japan, and the Philippines. From 

 1909-1914 he was in the Forest Service of 

 the United States, where he had wide exjaeri- 

 ence in field problems and editorial work. 

 Since 1914, when he left the government ser- 

 vice, he has devoted himself to research work 

 in silvies and silviculture. He is the author 

 of numerous papers on forestry problems.
