thee can readily perceive, and the third too if thee knows that a pe- 
culiarity of the Rasorial order, and its representatives, consists of 
crests, topnots, horns (as in the Ruminantia, and Rasorial type among 
mammalia) and also eyes like spots, and rich brown markings which 
thee knows run through partridge, grouse, pheasant, turkey, peacock, 
guinea fowl, and hundreds of others. 
"Thus it is that four of the orders of birds are typified among a 
subdivision of the owl family. The comparing of the five orders of 
birds with the same of mammals brings out some pretty results thus —

The circle, i. e., the connections between the last and first is com- 
pleted among the birds by such as the gulls and albatross which com- 
bine the webbed feet and aquatic habits and food of the Natatores 
with the powerful structure and raptorial manners of the Raptores. 
Among the mammals it is completed by the Seals, which belong to 
the Ferae but have many points of resemblance to the whales 
(Cetacea). And there are just such links between nearly alj 
the Orders, Families, Genera, etc., etc., throughout Nature, whether 
among animals or plants." 
The following year (July 7, 1858), a letter of eight closely 
written pages from Jennersville discusses with his father the 
merits of a large number of trees for transplanting to the 
family place at Fairfield. It shows a vast acquisition of botani- 
cal information and ends with a classified inventory of 348
