PEEFACE, 
mology was the particular branch which at 
that period I most studied. Hence a large 
(perhaps an undue) portion of the remarks 
concerns Insects ; and this may perhaps be 
the rather tolerated, because less is known 
in Europe of American Entomology, than 
of other branches of Zoology, which are 
popularly studied. 
These letters have already appeared in the 
form of contributions to a magazine entitled 
“The Home Eriend.” They have been re- 
vised, and are now reproduced, in the hope 
that they may prove a not wholly valueless 
contribution to Natural History.
