Thirty naturalists have occupied tables in the Laboratory for 

 longer or shorter periods, several of them on more occasions than 

 one. There is every reason to hope that this number will grow 

 steadily larger ; the existing accommodation for eleven (includino- 

 the staff) can easily be increased when necessary at small cost. It 

 is also worthy of notice that live and dead specimens have been 

 supplied to nearly every University and College which offers a 

 zoological course to its students, and to many private individuals. 



With this constantly enlai'ging sphere of usefulness, however, 

 the want of a suitable vessel is every day more strongly felt ; even in the 

 best of weather it is not advisable to go more than two or three 

 miles from shore in our little steam-launch, and it is frequently 

 impossible to go outside the Breakwater. With a larger vessel, not 

 only would it be possible to supply material to the naturalists 

 working in the Laborator}^ in greater abundance and variety (com- 

 manding as we could the rich stretch of coast from Mount's Bay to 

 Tor Bay), but it would be in the jjower of the Association for the first 

 time to undertake continuous and systematic investigations into the 

 problems of the spawning-grounds , nurseries, and migrations of food- 

 fish, valuable work such as the " Garland " is at present doing for 

 the Scottish Fishery Board. A Laboratory is only half, although 

 a necessary half, of the equipment required to attack fishery 

 problems. As far as possible its work has been supplemented by 

 occasional expeditions on trawlers, &c, but observations made in 

 this way are necessarily scattered and incomplete. A vessel able 

 to keep the sea in any weather with the fishing fleets would cost 

 between £2000 and £3000, and if maintained the whole year round 

 with a full crew would probably not cost less than £1200 per 

 annum. The "Special Steamboat Fund" was practically exhausted 

 by the purchase of the steam-launch; and the Association has no 

 funds sufficient either to purchase or to maintain this absolute 

 necessity of its efficiency. 



With regard to the present number of the Journal, which com- 

 pletes the first volume, special attention is called to Mr. Cunning- 

 ham's successful rearing of larval fish (p. 370), which is of the
