helped in various other ways. It is one of the advantages 

 of such an investigating trip that everyone on board can be 

 given some useful work to do. Another great pleasure is that 

 one is able to collect material, which perhaps could not 

 otherwise be obtained, for various scientific friends elsewhere 

 who are at work on special problems. 



FORAMINIFERA. 



The 24 canvas bags of mud, sand and other dredged 

 deposits are now being examined by Messrs. Heron- Allen and 

 Earland who are preparing a monograph on the British 

 Foraminifera. These gentlemen have kindly supplied me with 

 the following general notes on their results in regard to the 

 first four samples examined. They have kindly enabled me to 

 print also a list of the 259 species which they have picked out 

 from these four samples to show how rich, in these minute 

 and beautiful shells (see figs. 10 to 13), are many of the marine 

 deposits of the Hebridean Seas.
