the work on the surface-plankton and made several interesting 
observations on the dates at which certain organisms first 
made their appearance: he also made extensive collections 
of the littoral and shallow-water fauna of this region. In 
July, 1913, Captain Sewell again reverted to the post of 
Surgeon-Naturalist. 
The biological work of the Marine Survey of India has 
thus been in progress for nearly forty years, for the whole of 
which it has been carried out in close, o though generally 
informal, connection with the zoological section of the Indian 
Museum. Proposals are now under consideration which, if 
carried out, will have the effect of rendering the union still 
more intimate. 
A list of the biological stations of the two ' Investiga¬ 
tors,’ with data as to depths, temperatures, etc., has re¬ 
cently been published by the Museum authorities, who will 
be glad to send copies to those who are working at deep-sea 
biology.
