18 REPORTS. 



With regard to the bonnet-limpet, a specimen which I 

 had for a month or more, hardly moved at all for the first few 

 weeks, and returned to the same spot on the glass when it did 

 move. Then it began to move a great deal and did not 

 return to its old home ; within a Aveek we found its empty 

 shell showing that those useful aquarium scavengers — the 

 crabs — had found it off its support, either dead or alive, and 

 disposed of it. 



The experiments on the " homing " of limpets have been 

 continued in various parts of the shore and are still in progress. 

 It seems probable that in our hard rocks the " home " is not 

 so definite as in the softer rocfe of South and East coasts of 

 England, and that the limpet settles down in the first 

 comfortable spot, which is in many cases its old home. 



We have not succeeded in keeping the ormer alive in 

 captivity for more than a month. A good deal of attention 

 has been given to marine aquaria and one evening meeting 

 was devoted to the subject. As it is quite easy to keep 

 a marine aquarium for months or even years without ever 

 changing the water, it is hoped that more members will do so. 

 An immense amount of work may be done with it, and 

 unlike shore work, neither weather nor tide interferes with it.

REPORT OF THE GEOLOGICAL SECTION. 

 RAISED BEACHES. 



Cailloterie, St. Sa?npson's, and Grande Maison Road^ Vale. 



The remains of a fairly sized raised beach have been 

 exposed on the W. and N.W. sides of the Cailloterie 

 Hougne, Rue des Cottes, St. Sampson's. This deposit is 

 at a level exceeding 50 feet above mean tide. A similar 

 but smaller deposit is to be found at Jussien Quarry, 

 Grande Maison Road, Vale. The elevation corresponds. 

 Both these deposits are apparently felloAv ones to those at 

 the Capelles and at Noirmont. 



OTHER SUPERFICIAL DEPOSITS. 



St. Andrew's Road. 



Further excavations at the back of the house purchased 

 by Mr. Best from Mr. Nant, confirm the anticipations ex- 

 pressed in last year's report, as to the dip of the deposits 

 towards Talbots Valley.
