80 STUDY OF NATURAL HISTORY. 
We have already mentioned the entomological works 
of Scheffer, which might with equal propriety be 
classed in the present enumeration; for though their 
author admitted genera, he rejected specific names, 
and described his insects in the obsolete style of the 
early entomologists. The volume of Duhamel, upon 
Ichthyology, is now chiefly valuable for its figures: 
while those of Sonnerat*, wherein a large number of 
Indian birds are tolerably described, but wretchedly 
figured, are of little use; there are no determinate or 
scientific names; and the descriptions puzzle, rather 
than assist, the ornithologist. Sonnini+, one of the 
engineer officers of the French army in Egypt, is 
chiefly known, as a naturalist, by the edition of 
Buffon which bears his name. It is the most copious 
we have seen, and the best; being enriched with 
many original observations of the author made upon 
the spot upon the birds of Cayenne. In his Egyp- 
tian narrative, which was translated into English, 
will be found descriptions and figures of many of. 
~ the new fish of the Nile.

is the celebrated Le Vaillant, an enthusiastic tra-
