nets, but can be obtained by centrifuging samples of sea-water. The 
samples examined have been taken at frequent and regular intervals 
during the year by means of a water-bottle, which has been worked at 
several different depths, generally near the surface, about mid-water 
and near the bottom, at the entrance to Plymouth Sound. A numerical 
estimate has been made of the number of organisms of each kind in 
the individual samples. Miss Lebour has also undertaken the examina- 
tion of a series of samples obtained by means of tow-nets during the 
last few years, at fortnightly intervals, at the Seven Stones Light Vessel, 
midway between Land’s End and the Scilly Islands. 
Mr. W. O. R. King, assisted by Mrs. King, spent some time at the 
Laboratory as Ray Lankester Investigator, and continued his work on the 
temperature coefficient of development of Hchinus. 
Mrs. EK. W. Sexton has completed a paper on the Mendelian inheritance 
of eye-colour in the Amphipod, Gammarus chevreuxi, which is being 
published in the next number of the Journal.

The Library. 
The thanks of the Association are due to numerous Government 
Departments, Universities and other institutions at home and abroad 
for copies of books and current numbers of periodicals presented to the 
Library. The list is similar to that published in the Reports of Council 
of former years. A number of authors have been good enough to send 
reprints of their papers for the Library and to these also thanks are due.
