lates through the aquaria and finally runs into a sand-filter in the base- 
ment to be again pumped into the upper tanks. Every fourteen days 
a fresh supply is pumped in from the sea. A perfectly developed system 
of collecting enables the institution to exhibit the most beautiful and 
interesting animals of the bay of Naples in large numbers and in the 
best condition. A little book published in Italian, German, French 
and English gives, in simple language, just such a description of the 
animals, their habitat and behavior, as will appeal to the public. There 
are many “happy families” formed upon long observation of the 
different kinds of animals that may live together without acquiring too 
marked a taste for one another. The aquarium containing the coral 
animals is constructed like a grotto under the arch of which one sees 
the orange-colored polyps spread about like marigolds. Some of the 
related anemones are actually old, as is shown by their long, wrinkled, 
thick-skinned bodies, but their straight, or slightly curled tentacles of 
purple, or lavender, or cream-color, or brown, are most beautiful.
