FISHERIES CATALOGUE. 219 



CASE B contains printed matter, plates, photographs, 

 and drawings illustrating the publications, both adminis- 

 trative and scientific, of the Lancashire Sea-Fisheries 

 Committee, and other work bearing upon the fisheries of 

 the district. 



One end of the case is occupied by the series of photo- 

 graphs taken recently by Mr. Andrew Scott to illustrate 

 Mr. Dawson's lecture on the methods of fishing in Lan- 

 cashire. These show the appearance of the fleets and 

 the fishing boats, of different kinds, in different positions, 

 and also such peculiar methods of fishing as the cart 

 shrimp net, the power net, using the "jumbo" and the 

 " craam," and " treading for cockles." 



The opposite end of the case contains a set of drawings 

 and water-colour sketches, made by Professor Herdman, 

 in illustration of his joint investigation with Professor 

 Boyce, on "oysters and disease." These show the 

 external appearance and the internal structure of various 

 kinds of oysters — natives, French, Dutch, and American, 

 in both healthy and unhealthy conditions. Some of the 

 drawings represent the minute structure as seen under 

 the microscope. 



A further series of drawings, and a large number of 

 specimens, microscopic and otherwise, in illustration of 

 the oyster investigation, will be found in another case. 



At this same end of Case B, below the drawings, are 

 exhibited some series of the microscopic slides which are 

 prepared in the laboratory in the course of the scientific 

 investigations. Some of them are thin sections of fishes 

 and other marine animals, others are scales, eggs, em- 

 bryos and various pieces of internal organs, prepared, 

 stained, and mounted for microscopic examination.
