FILARIA OCULI. 
By the Same. 
Perhaps the little worm. Filarici oculi , I have inclosed in 
this will keep, as it has been in spirits for twelve months. 
I removed it from the eye of a horse, by puncturing the 
cornea in the way generally described. These little worms 
are the cause of much trouble here. It is not pleasant to 
puncture the eye, although the inflammation subsides quickly.

BOTANY AS APPLIED TO VETERINARY SCIENCE.

{Continued from page 260.) 
Before describing the subdivisions of the Natural system, 
it will, perhaps, make the subject more clearly understood if 
a brief outline of the different parts entering into the forma¬ 
tion of a flower be given. 
A Flower, when perfect, consists of the following parts, 
which may be readily observed 
in the blossom of the common 
wall-flower. (See fig. 1.) 
Supported on its peduncle (a) 
we find externally the calyx (< h ), 
next the corolla (c c), within 
that the stamens (< d ), and in the 
centre the pistil (e). 
Each of these parts is not 
always present. Sometimes 
the calyx is absent, in others 
the corolla, and in some plants 
both. The only really essential 
parts belonging to a flower are 
its reproductive organs, viz., the stamens and pistil, with 
their appendages; constituting, the former the male, the latter 
the female, organs of the plant. 
Most plants have the male and female organs together in 
the same flower, and are then called hermaphrodite; but in 
some instances, although the same plant has both male and 
xxxii. 51
