The lecturer pointed out that, as far as the plankton was concerned, 

 the water of Lough Neagh was very prolific. For the whole year 

 there is a total volume of plankton produced per cubic metre 

 which exceeds that of the waters of the Irish Sea. This plankton 

 is very similar in character to that of some North European lakes 

 and differs considerably from that of the Scottish lochs and lakes 

 of the English lake district. The resemblance to certain North 

 German lakes is still further increased by the presence of My sis 

 reiicta, which though not strictly speaking a planktonic organism, 

 must be considered with the plankton. In conclusion, Dr. Dakin 

 drew attention to the remarkable fact that, whereas on land the 

 most productive regions are in the tropics, the conditions are 

 reversed in the water, and both fresh-water lakes as well as the 

 seas and oceans in temperate and Arctic regions are far more 

 productive, as far as plankton and fish-life is concerned, than 

 tropical waters. 



The President and Messrs. Cunningham and Whitehouse 

 having raised points for discussion, Dr. Dakin briefly replied, and 

 the election of Miss Jane E. Montgomery and Messrs. H. 

 M'Clelland, J. D. W. Stewart, and Herbert M. Thompson to 

 membership brought the meeting to a close. 



FOGOUS AND OTHER CORNISH ANTIQUITIES. 



A meeting of the Archaeological Section was held on 29th 

 March, Miss E. Andrews presiding, when Mrs. Hobson read a 

 paper on above subject. In the course of her address, Mrs. 

 Hobson said it could never be possible rightly to appraise the 

 importance of any archaeological remains in any given district or 

 country without some comparison with the same class of objects 

 in other places and other lands in order to see things in their true 

 proportions and get at their proper values. It was with the object 

 of comparing the " souterrains " in Ireland with the " fogous " in
