Goodrich, in his Geography, enumerates the following species in the United 
States, viz :— ‘ 
1. The American Elk, or Wapiti, C. Strongyloceros. 
The Moose, C. alees Americanus. 
The Caribou, or American Reindeer, C. tarandus. 
Common Deer, C. Virginianus. 
The long-tailed Deer, C. leucurus. 
. Whe black-tailed or Mule Deer, C. macrotis. 
The tegumentary appendages of all these species, so far as we have had an opportunity 
to examine them, have a great sameness of structure ; sufficiently so to connect them into 
one group. ‘The cortex is paved, the divisions have the shape of compressed pentagons, 
octagons and polygons ; the coloring matter lies immediately beneath the cortex, the centre 
being colorless, and the shaft having no canal; the button is spindle-shaped, succeeded by 
a slender neck, the shaft is feebly flexible, bending at right angles; the ductility very 
considerable, but accompanied with little elasticity or tenacity.* 
We will now give a particular description of a hair of one of the species. 
1. The Stag or Deer, Cervus elephus.—Specimen Jrom the Western part of the State.— 
Hair.—Length, about 2 inches; greatest diameter, 515, and least diameter, 45 of an inch ; 
button, po epee length, oo of an inch, and diameter, 74, of an inch. Neck— 
Length, ,3, of an inch; diameter, ;}> of an inch, gradually widening to a stalk.t Apex, 
gradually tapering to a point; color, for one inch and 5% white, opaque, gradually darken- 
ing for ;% of an inch, succeeded by light brown or fawn color, and terminating in black at 
the apex. The whole stalk is undulated, the highest waves of which are in the centre. 
The interstices between the paved portions, darker colored than that of the pavement ; 
flexibility feeble, bends at right angles, and remains bent. No central canal. 
Ductility, Elasticity and Tenacity—May 11th, 1849.—One inch with 170 grains was 
deprived of its undulations. Upon removing this weight the undulations returned. 
With 180 grains it stretched 2 
aap wy 
of an inch, elasticity entire.

* Perhaps a large portion of the animal vitality conveyed to the exterior is expended on the horns. 
+ When the part that widens is observed on its flat sides, the paved cortex is seen on it; while on the elipsoids the cortex 
appears plain.
