On entering upon the yeui's occupancy of the Naples Table the advis- 

 ability suggested itself of sending a circular letter to teachers and others 

 likely to recommend workers ; and as the result a greater number of 

 applications were received than it was possible to grant. Among those 

 which were entertained no fewer than three ultimately overlapped during 

 spring, and the best thanks of the Committee are hereby tendered to Dr. 

 Dohrn for his magnanimity, exceeding all precedent, in having arranged 

 for the accommodation of all woi'kers recommended, this notwithstanding. 

 The indebtedness of the Committee is further increased by his having, on 

 their behalf, granted Professor Ramsay Wright, of the University of 

 Toronto, permission to .spend the leisure of two months' residence in Naples 

 in tlie study of the methods of capture and preservation in vogue in tho 

 bay, witli a view to their application at tlie New CJanadian Marine 

 fStation, the project for which received the support of the British Asso- 

 ciation. And this has been further increased by his having allowed Miss 

 A. Vickers to collect seaweeds between October and January, on the 

 recommendation of the Committee. 



The list of British woi-kers at the Naples Station which accompanies 

 this Report exceeds, as regards numbers, all previous records, while that 

 of naturalists of other countries reaches for the year seventy-four in all, 

 bringing the total of those who have profited by the resources of the 

 establishment since 1873-74, when Professor Waldeyer and the late 

 Francis Maitland Balfour began work there, to nearly 1,200 persons.
