basement floor has been devoted to the interests of the general visitor, and a well-chosen collection representing the Channel fauna can be studied in its well-arranged tanks. The important work of the station in connection with the British fisheries, added to its exceptional advantages in collecting material, gives Plymouth an important rank among marine aquariums.

The great height of the tanks is particularly noteworthy; in some
