Naples Station : General Description and Notes 

 on Methods of Work Employed There. By 

 De. E. O. Hovey. 



This laboratory was established in 1872, 

 by Dr. Anton Dohrn. Although some 

 thirty stations have since been established 

 on similar lines, this has maintained its 

 lead in importance. The most popular 

 feature is the aquarium, which consists of 

 26 tanks (described in some detail). The 

 chief function is investigation, which is car- 

 ried on by a corps of nine regular officials, 

 and 30-40 students from all parts of the 

 world. More than 1,000 men have studied 

 at the Laboratory. An important feature 

 is the beautiful preparations of the Naples 

 marine fauna, which are sent to museums 

 and investigators all over the world. The 

 paper presented many interesting and prac- 

 tical details of methods employed. 



General Statement of Types and Figured Speci- 

 mens of Fossil Invertebrates in the American 

 Museum of Natural History. By Dr. E. 0. 



HoVEY. 



The Museum has at least 8,000 types and 

 figured specimens of fossils. A large part 

 of these are in the James Hall collection, 

 including a large proportion of species of 

 the New York Palaeozoic horizons; also im- 

 portant series from Waldron and Spergen 

 Hill, Indiana; Kacine, Beloit and other 

 localities in Wisconsin and Minnesota. 

 The Museum has the F. S. Holmes collec- 

 tion, including many Tertiary and Post- 

 Tertiary types from South Carolina; the 

 typesof Hall and Meeky from theCretaceous 

 of Nebraska and many types of species de- 



scribed in the Bulletin of the Museum. In 

 the paper a number of other lots of tj'pes 

 and figured specimens are mentioned which 

 cannot be referred to in this brief abstract. 



Ink and Paper for Museum Labels. By De. 



Egbert T. Jackson. 



Dwelt on the importance of carbon 

 writing and rubber stamp inks, as being the 

 only inks suitable for permanent records. 

 Bond or linen record paper advised as be- 

 ing lasting. Ordinary paper not suitable 

 for permanent records. This paper will be 

 published in this Journal.

 section b at the boston meeting. 

 The program of Section B contained fifty 

 titles of papers, forty of which were read in 

 full. Many of these papers were of high 

 order and almost every one was creditable 

 and interesting. The increasing activity 

 of Section B and its growing membership 

 are matters for congratulation, and it is 

 probable that an affiliated American Phys- 

 ical Society may soon become desirable and 

 feasible. The proceedings of Section B will 

 be reported in Science at an early date. 



THE FLOW OF WATER IN PIPES. 



The flow of water in pipes and channels 

 is again the subject of elaborate investiga- 

 tion,* but it is doubtful whether anything 

 more than roughly approximate formulation 

 of the laws of flow of water can ever be 

 reached. It seems that the slightest rough- 

 ness on the inside of a pipe leads to unstable 

 states of fluid motion resulting in the forma- 

 tion of eddies. If incipient eddy motion 

 is indeed an unstable state of fluid motion — 

 and our knowledge of vortex sheets, such, 

 for example, as the air jet of an organ pipe, 

 seems to show that it is — then the flow of
