Once again this Report will deal with little beyond the

in 1916 we had twenty-one, and the present report again shows 
twenty-one. The number of visitors to the Aquarium is larger 
_ than it was in 1915, but is far below the numbers usual in 
previous years. , 
In regard to the educational work in the laboratories, 
the usual Easter vacation course in Marine Biology was carried 
on during April by members of the staff of the Zoology 
department of the University of Liverpool, and was attended 
by 12 undergraduates. 
Work out at sea was wholly prevented, by Admiralty 
regulations, but collecting expeditions as usual, along the

collections from time to time as occasion offered, and plankton
