in which is included all the men employed, the 

 maintenance of the building, the manipulation of 

 the fish, carriage, packing, travelling expanses in 

 collecting the ova, purchase of ova, salaries, &c., 

 including the entire operations from 1853 to 1862, 

 amounts to 347,186 francs, or say 13,887/.; the 

 average annual expenses during the past four years 

 have been 55,000 francs, or say 22001. 



The ova are collected and impregnated at remote 

 places, they are then conveyed to Huningue and 

 partly hatched ; after which they are packed, for- 

 warded, and distributed to such rivers as may require 

 a supply. For the past two years the establishment 

 has also distributed young fry by way of experiment, 

 but this mode cannot be greatly extended, owing to 

 the increased expense and difficulty of transit. 



The following tabular statements of the result of 

 operations are interesting, as they show the various 

 kinds of fish that have been artificially propagated 

 in the season of 1861 :
