similar reports having been current in Europe
respecting America Prot Agsssiz was led 70 in

OF observing them. The frat occurred Ia the year

catfish were following their parents closely
There was nothing in this instance, however which
indicated any special regard OF the latter FOR their

fourth and fifth time, with the same result The

these interesting facts, the Professor argued the

In their mature growth but In every stage Of their
existence and the necessity Of close and accurate
observations Of the phenomena attending the de-
velopment OF their successive period His remarks
were listened to with much attepton.
