46 PENIKESE. 



were lying upon the table ready to be skinned and 

 mounted or dissected and bottled as were our other 

 anatomical specimens. 



Then we go -to our lecture room and take notes 

 from our Professors as they talk to us. Well do I 

 remember how hard Professor Morse labored to im- 

 part to us some knowledge of the Molluscous kingdom, 

 or the so-called shell-fish. He told us of their position 

 in the- animal kingdom, of how they were grouped 

 among themselves, of the internal structure of each 

 group, andof the life histories of many of the indi- 

 vidual species. . Under his direction, we dissected 

 many of the larger sea molluscs, which we captured 

 in our nets and on the beach at low tide, and found 

 it a most pleasing occupation, to follow out the va- 

 rious systems which they exhibited, and to compare 

 them with those in both the higher and lower groups. 



I remember that one of his lectures was devoted to 

 the Snails. In it he told us of this great group, 

 how that they were called by naturalists the Pulmo- 

 nata from the Latin pulmo, a lung; and/m?, I bear 

 signifying; that which they in truth are, the lung- 

 bearing mollusks. Then he explained to us the three 

 great groups into which they were divided. How 

 well I remember those terrible names for I learned 

 them by heart, so that I could repeat them and their 

 meanings over and over again the Geophila, from 

 two Greek words which mean earth and loving, re- 

 fering to their terrestrial habits; the Limnophila, also 

 from two Greek words which mean lake or pond [fresh 

 water] and loving, owing to the fact that while the 

 former live on the land the latter prefer the shores 

 and mud-flats of, and mud in, fresh water pools, 

 ponds, and lakes; and the Thalassophila, or those 

 which love or live in the Greek thalassa or the sea, 

 these being marine. His remarks were confined 

 mostly to the first two groups, more especially to the 

 land snails. He told us: how they lived under rocks, 

 stones, boards, the trunks of fallen trees and beneath 

 their bark, and even amongst the decayed leaves of
