Naturalists, Messrs. L. E. Crawshay, J. H. Orton and E. S. Clark. 

 The latter has recently been appointed to make investigations on the 

 biology of marketable fishes. . 



Occupation of Tables. 



The following Naturalists have occupied tables at the Plymouth 

 Laboratory since the last report was presented to the Association : — 



Prof. Chas. Chilton, d.sc, New Zealand (Amphipoda). 



J. Clark, d.sc, Kilmarnock (Crustacea). 



W. De Morgan, Plymouth (Protozoa). 



G. H. Drew, b.a., Plymouth (Tissue Cirowth). 



F. Martin Duncan, Oxted (Photography of Marine Animals). 

 H. M. FucHS, Cambridge (Echinoderm Development). 



J. Gray, Cambridge (Echinoderm Development). 

 H, Henry, m.d., Sheffield (Parasitic Protozoa). 



G. J. Hill, London (General Zoology). 



H. B. Johnston, Oundle (General Zoology). 



S. P. Kramer, m.d.. New York (Elasmobranchs). 



Miss D. Jordan Lloyd, Cambridge (Echinoderm Development).

General Work at the Plymouth Laboratory. 



During the six months covered by the present report the staff 

 have for the most part been employed in a continuation of the re- 

 searches then described. The Director's experiments on the conditions 

 of growth of plankton diatoms have made considerable progress and 

 results of great scientific interest are promised. Mr. Matthews's in- 

 vestigations on the chemistry of sea-water have to some extent been 

 interrupted by the preparation of a report on the hydrographical work 

 of the Irish Fishery Department, by whom Mr. Matthews is in part 

 employed. 



Mr. L. E, Crawshay's report on the fauna of the deeper portion of 

 the English Channel to the south-west of the Eddystone has been 

 published in the Journal of the Association. This report, in conjunc- 

 tion with the previous papers by Mr. Crawshay and Mr. Worth on 

 the bottom-deposits of this region, forms a valuable addition to our 

 knowledge of the English Channel both from the biological and 

 geological points of view.
