OSTREIDiE. 
Ostrea ediilis (L.). Z. Gerbe has examined 435 oysters, one year old, 
and found in 35 of them young within the gills, in 127 the ovaries full 
with eggs, and in 189 spermatozoids ; they are consequently able to 
propagate in the first year. R. Z. (3) iv. pp. 274-278. The annual 
decrease of the results of oyster-fishing on the British coasts have been 
the subject of a Commission appointed by Parliament ; in the report of 
this Commission the fact is acknowledged, and attributed to the im- 
moderate and rapacious method of fishing ; several remedial measures 
are proposed. A German translation of this Report is to be found in 
the “ Circulare des deutschen Fischerei-vereins,” 187G, No. G, pp. 
211 - 221 . 
A. Lafont has published a popular account on oyster-breeding.

1874, 8vo, 52 pp.)> Bon another, “Notice sur la situation de 
r Ostreiculture en 1875“ (Paris: 1875, 8vo, 27 pp.), this latter is pub- 
lished also in the “ Revue maritime et coloniale “ of the same year. 
Historical notes on oyster-fishing on the coast of Eastern Friesland in
