The collections have continued in excellent condition and all 
exhibition space is filled to its utmost capacity. The construc- 
tion of a large number of new tanks with increased depth has 
added greatly to the capacity of the building and to the interest 
of the exhibits. 
The principal additions during the year were about 1,000 
tropical fishes from Florida, five porpoises, an eight-foot shark, 
and a manatee from the Amazon. The porpoises and shark died 
during the year, but the manatee is living and is in excellent 
condition. The collection of tropical fishes is an unusually fine 
one. 
The only serious loss during the year was a collection of 
fishes secured in the Bahama Islands, which was destroyed dur- 
ing a hurricane in July.
