16 ANNUAL REPORT OF THE 



The Virginia Barret Gibbs Scholarship was held by Mr. H. W. 

 Rand. Eight students working at the U. S. Fish Commission 

 Laboratory, Wood's Hole, in the summer of 1900, received aid 

 from the income of the Humboldt Fund. 



The meetings of the Zoological Club were held weekly during 

 the greater part of the year on Thursday afternoons from 4.30 to 

 6 o'clock, and were attended by from 15 to 20 persons. 



Professor Parker has published in the Contributions Nos. 100 

 and 110, and jointly with a student of Radcliffe College No. 101. 

 He has also published " Studies from the Newport Laboratory, 

 No. 42," in the Museum Bulletin ; a lecture on " The Neurone 

 Theory in the Light of Recent Discoveries," in The American 

 Naturalist, June, 1900 ; and reviews for Science and The Ameri- 

 can Naturalist. Dr. Castle has published in the Contributions 

 two important papers, Nos. 108 and 112, on Hirudinea, and 

 reviews in The American Naturalist. 



The need of better lighting for the work tables of the labora- 

 tories has long been evident ; the want of good light is especially 

 felt during the short days of autumn and early winter. Soon after 

 the beginning of the year, the large lecture room on the fifth floor, 

 which is also used as a laboratory for students in Zoology 1, was 

 furnished with electric lamps and shades pendant from movable 

 brackets and adjustable to any desired height, one over each table. 

 The arrangement has proved to be highly satisfactory. Clusters 

 of electric lamps for the general lighting of the laboratory on the 

 second floor were also introduced. Through the courtesy of the 

 Department of Mineralogy and Petrography these lamps were 

 lighted from the dynamo belonging to that department. In addi- 

 tion, the work tables in three of the laboratories that were already 

 conveniently supplied with gas piping were fitted out each with a 

 single Welsbach burner and shade. The piping of the table is 

 permanently attached to the under side of the top, and is easily 

 connected with the wall piping by means of short rubber tubing. 

 This arrangement will allow the use of such tables in any other 

 room without further outlay, should it be found necessary in the 

 future to shift a laboratory from one room to another. .
