 these sources. 



Beyond them lies the nebulous myriad of papers 

 scattered in technical journals. For zoologists the 

 best path is the card-catalogue prepared by the 

 " Challenger " Society ; by this means it is possible to 

 find all that has been published on the marine fauna 

 of a region, or even of a lonely island. But many 

 Reports of Expeditions contain very full lists of special 

 papers. 



General zoological and botanical textbooks of all 

 grades are only too numerous. For the purposes of 

 the reader whom we have in mind, the volumes of the 

 " Cambridge Natural History" are to be recom- 

 mended, and on the botanical side Murray's " Intro- 

 duction to the Study of Seaweeds " will be found 

 helpful. Anatomical and systematic textbooks are 

 beyond the scope of this work.
