V THE INTERNATIONAL FISHERIES EXHIBITION 213 



on the Florida coast, and in the American Court are 

 two sticks with sponge-cuttings growing upon them, 

 which have been artificially placed there. I am not 

 aware as to whether any valuable result has been 

 obtained by thus cutting the sponges ; but it is 

 certain that they might be thus introduced into 

 artificial basins, and grown there, were the general 

 conditions in such basins favourable. 



Coral fishery is represented by an exhibit from 

 Naples, and by three pieces of valuable red coral 

 from Japan which have been purchased for com- 

 mercial purposes at a high price. The eminent 

 French zoologist, Lacaze Duthiers, under the direc- 

 tion of the French Grovernment, made a very thorough 

 study of red coral, and obtained scientific results of 

 great importance, fitted to assist the coral fishermen 

 in the regulation of their fisheries and the culture of 

 coral ; but these results are not in any way illus- 

 trated in the present Exhibition. 



On the whole, it appears when one attempts to 

 enumerate the results of zoolosfical science in relation 

 to fisheries — illustrated in the present Exhibition — 

 that there are but few results which are so illustrated 

 — in fact not nearly so many as one might have ex- 

 pected. But, on reflection, it will appear that it is 

 diflicult to show, in the form of a tangible exhibit, 

 many of these results. They are for the most part to 

 be found in books, and in the memoirs and illustrative 

 drawings published by scientific societies. Microscopic 

 preparations, showing every detail of the growth from
