437 



feet of Cambrian limestones, sandstones and 

 shales, in which fossils were found at many 

 horizons. Large collections of rocks and fos- 

 sils have been sent to the United States Na- 

 tional Museum. 



The expedition from the Peabody Museum 

 of Harvard University to South America, 

 under the patronage of Louis J. de Milhau, 

 has returned. The past tliree years have been 

 spent in explorations on the headwaters of the 

 Amazon River in the interior of Peru and 

 Bolivia. The primary object of the expedi- 

 tion was the study of the native tribes of these 

 little known regions. Lucidentally, collections 

 were made in natural history, meteorological 

 observations were taken, and topographical 

 work was done. A map of the entire region, 

 based on traverses and astronomical observa- 

 tions, was made for the Peruvian government. 

 The field work of the expedition was done 

 under the direction of Dr. William Curtis 

 Farabee, assisted by Dr. E. F. Horr, Mr. L. J. 

 de Milhau and Mr. J. W. Hastings. 



Mr. Delos Aknold, donor of the Arnold 

 Geological Collection of the department of

Mr. Thomas Southwell, of Norwich, 

 known for his work on ornithology and on 

 whales, died on September 5, at the age of 

 seventy-nine years.

 Friday evening at which papers on the struc- 

 tural and glacial features and the anthropo- 

 geography of the region will be read and the 

 outline of the excursion of the next day will 



be given. More detailed notices will be sent 

 to all geologists and geographers who have at- 

 tended former excursions and to others who 

 will write to the secretary, Herdman F. Cle-

The public museum of the Staten Island 

 Association of Arts and Sciences, in Borough 

 Hall, New Brighton, should be added to the 

 list of institutions in which commemorative 

 Hudson-Fulton exhibits have been installed. 

 This exhibit, which was opened with appropri- 

 ate ceremonies on September 4, the actual 

 anniversary of Hudson's landing on Staten 

 Island, is designed to illustrate the historical 

 development of the island during the past 

 three centuries. The original fauna and 

 flora is shown, either by actual specimens or 

 explanatory labels; the Indian occupation of 

 the island is well illustrated by implements of 

 agriculture, war and the chase, and by a model 

 of a Manahatas Indian village. The colonial 

 period is represented by various old prints, 

 maps, a collection of antiques, etc. There is 

 also a model of the water gate at the foot of 

 Pearl Street during the Dutch period, and a 

 model of the interior of a typical Dutch home. 

 The costumes of various nationalities which 

 have contributed to American citizenship are 

 also shown. The museum is open from 1 to 5 

 P.M. daily except Monday; on Saturdays it is 

 open from 10 a.m to 5 p.m. 



A letter has been received at the Harvard

 stating that Halley's comet was observed visu- 

 ally by Professor S. W. Burnham with the 

 40-inch telescope, on Sept. 15" 21" 39"" G. M. T., 

 in App. R. A. 6" 18"^ 51M and App. Dec. + 17° 

 9' 44". The comet followed B. D. + 17° 1232 

 by 12'.7, North 4' 12".l. The comet was also 

 photographed with the 2-foot reflector, on Sep- 

 tember 15 and 16, by Mr. Oliver J. Lee. A 

 second letter from Professor Frost states that 

 the comet was also observed visually by Pro- 

 fessor E. E. Barnard, on Sept. 17" 21" l"" 30'
