a business of it, principally, from the Ehine, the 

 Danube, and the lakes and rivers of Switzeriand and 

 Germany. The tariff for collecting these eggs was 

 about two francs per thousand ; but it was found that 

 immature eggs were sometimes sent, and a difficulty 

 of proper carriage resulted; and now the plan adopted 

 is as follows : The establishment is in correspondence 

 with all the principal fishermen at the above places. 

 When any of these fishermen have collected together 

 a large number of fish in a spawning state, they send 

 notice of it to Huningue, and one of the manipulators, 

 of whom three or four are kept upon the establish- 

 ment, is sent to take the spawn, and bring it to 

 Huningue ; a certain fixed sum being paid per 

 thousand for the various species of ova to the fisher- 

 men, who then sell the spent fish for food. The 

 eggs which are the most difficult to obtain are those 

 of the Ombre Chevalier ; they cost the establish- 

 ment nearly one penny each. All the best kinds 

 of fish which we have iu England, and some which 

 we have not, as the Fera, the Huchen, and the Ombre 

 Chevalier, are included in their list of operations. 



When the applicant is successful in obtaining a 

 promise of spawn, printed lists are sent to him, one 

 comprising the fish which breed during the winter 

 months, and one of those which do not deposit their
