the Blackpool ground, and on the Mersey banks. — It 
seems unlikely that we shall gain much further, or more 
exact, information than we now possess with regard to 
the distribution and inter-relations of the shrimps and 
fishes with any less expenditure of time. Three hauls on 
different parts of the grounds should be taken during 
pach day’s work. It need scarcely be pointed out, how- 
ever, that these hauls would also give us statistics im 
regard to other fishes, and generally add to our know- 
ledge in various other useful directions. It would, pro- 
bably, be impossible to report satisfactorily upon all the 
matters referred to in the above outline in less than two 
years, and a consideration of the work and_ statistics 
required to solve the problems shows how necessary it is 
that we should have a second steamer in this district, 
devoted solely to scientific and statistical investigation.
