holds, as well as the instruments for the dissec- 

 tion of the larger zoological specimens. We have 

 already spoken of the laboratory servants, and 

 the bone-articulators and skin-stuffers, who are 

 personally and directly employed by the zoologist ; 

 and of the artists and photographers who depict 

 his specimens, or perhaps copy his drawings. We 

 must add to the list of the zoologist's helpers, 

 last, but not least, the printer who " sets " the 

 learned treatise in which the final result of his 

 work is usually embodied; and attendant on the 

 work of the printer is that of the bookbinder. 

 With the bookseller the zoologist has but little to 

 do ; the general public, even the reading public, 

 has no knowledge whatever of the writings of 

 the zoological specialist. They are addressed to 

 his equals and co-workers, not to critics and re- 

 viewers. Their publication is provided for, not 

 by the law of supply and demand, but by the 

 funds of the learned societies and the universi- 

 ties. It is only occasionally that a writer arises 

 who is able and willing, like Huxley or Darwin, 

 to express himself in a book that the general 

 public can read; and it is only after a lifetime of 

 detailed work, such as is understood only by the 

 specialist, that writers like these think it fitting 

 to lay the results of their labour before out- 

 siders. 



The librarian, finally, must not be forgotten, 

 in making up our list of the zoologist's helpers. 

 The preservation and cataloguing of zoological 

 literature is obviously a task all the more im- 

 portant, because, as we have already stated, 

 zoological writings are not regulated by the law 

 of supply and demand. A very little paper, read 

 to a very small meeting of a learned society,
