150 Mr . Thomas’s anatomical Description 
processes, arising by distinct tendons from the internal and 
posterior portion of the sclerotica, and at equal distances from the 
optic nerve. These processes passed forwards between the coats, 
gradually becoming broader, and being insensibly lost in, and 
forming a part of, the choroid, atthe broadest diameter of the eye: 
the connexion between the coats around the outer circle of the 
cornea, was the same as is observed in the eye of other animals. 
The processes had a muscular appearance ; the fibres running 
forward, in a radiated direction ; they were detached from the 
coats with the greatest facility, except at their origins and in- 
sertions, where it required considerable force to tear them from 
the sclerotica ; and, at their terminations, they became so inti- 
mately connected with the choroid, as to form only one sub- 
stance. On neither of their surfaces was there any thing similar 
to the nigrum pigmentum ; the pigment was confined to the in- 
side of the choroid coat, without any structure similar to the tape- 
turn lucidum. The ciliary processes were affixed to the crystalline 
lens ; they were extremely short, and indistinct ; not having 
that beautiful arrangement commonly seen in the eye of other 
quadrupeds. The iris was circular, and of a dark brown colour. 
The crystalline lens was somewhat remarkable with respect to 
its form, being nearly spherical ; this was very strongly marked, 
when compared with the lenses of several other animals ; the 
anterior surface was a little flattened. 
The peculiarities already observed in the structure of the eyo, 
in different animals, are very numerous ; but I do not know 
that the variety above stated has hitherto been noticed by any 
one : the structure of the processes, as far as the sight can 
determine, appears to be muscular ; and, what more particularly 
tends to confirm this notion, is the very distinct tendons con-
