also sent contingents ; and in the daily round of shore collecting, 

 tow-netting and microscopical examination in the laboratory 

 much good work was done during the Easter vacation, under 

 the direction of Professor Herdman, Miss R. C. Bamber and 

 Miss Blackwell. 



" An important research into the seasonal variation in 

 the alkalinity of sea- water was conducted by Professor B. 

 Moore, who with his son, Mr. T. Moore, Mr. E. Whitley and 

 Mr. T. A. Webster occupied the bio-chemical laboratory during 

 the Easter vacation. They were followed in the work by 

 Dr. G. B. R. Prideaux of University College, Nottingham, 

 and the research was resumed and carried on for a fortnight 

 in July by Mr. T. Moore and Mr. Webster. During the latter 

 part of the Easter vacation Miss C. Mayne resumed her work 

 on the animal ecology of Port Erin Bay ; and in July Mr. G. F. 

 Sieggs, who succeeded Miss Mayne as Edward Forbes 

 Exhibitioner, spent a fortnight in observing the habits and 

 preserving specimens of the common barnacle, Balanus 

 balanoides, with a view to the authorship of an L.M.B.C. 

 Memoir upon that type. During the summer vacation Miss 

 E. C. Herdman, of Newnham College, Cambridge, re-discovered 

 the interesting Orthonectid Rhopalura giardii which occurs 

 as a parasite in the body cavity of the brittle-starfish Amphiura 

 elegans, and devoted much time and labour to the elucidation 

 of its structure. At the same time Dr. H. E. Roaf occupied 

 the bio -chemical laboratory and devoted himself to research 

 on the CO 2 in sea- water under different conditions. 



" Amongst a considerable number of anemones brought 

 in by several fishermen from the local fishing grounds was one 

 which was immediately recognised as probably new to our 

 fauna. It had, unfortunately, been injured, probably by a 

 fish-hook, and survived only a few days. Mr. T. A. Stephenson 

 of University College, Aberystwyth, to whom it was sent, 

 identified it as Ilyanthus mitchellii, a species not hitherto
