the cornea, arising when the structure becomes anaesthetic, be¬ 
cause it is severed from the influence of the trigemini.” 
u Cause :—The corneal lesion has been ascribed to a trophic 
change, to the lessened power of resistance to micro-organisms, 
which the cornea in its insensitive condition presents to external 
injury ; to the irritation to the fifth nerves and to increased 
evaporation from the surface of the cornea. Disease of the 
Gasserian ganglion. Disease of the nuclei of the fifth pair. 
Anything which cuts off trigeminal influence. Foreign sub¬ 
stances remaining undetected upon the insensitive cornea, 
whose resisting power is weakened through loss of trophic in¬ 
fluence.” 
“ Symptoms:—The corneal tissue is comparatively clear be¬ 
yond and around the central abscess. In periphery, there are 
secondary foci of infiltration closely connected with the inflam¬ 
mation of the neighboring conjunctiva. The surface of the 
cornea and conjunctiva is anaesthetic. There may be pain and 
irritation, or there may be abscess.”

“ When the fifth pair and particularly the part containing 
fibres of the sympathetic, is divided in animals, in a short time 
the cornea on that side begins to ulcerate and soon passes on to 
total destruction. Also when the fifth pair is from any cause 
paralyzed in man, and particularly when the branch going to 
the orbicularis muscle is involved at the same time. 
“ It is a point in dispute, whether the ulceration is due to in¬ 
terference with nutrition from injury to the trophic filaments of 
the fifth pair, or is simply the result of traumatic injuries, in¬ 
flicted on the insensitive cornea on account of its constant ex¬ 
posure from paralysis of the orbicularis. Injury to the trophic 
nerves seriously impairs the resisting power of the corneal tis¬ 
sue, and in some instances is itself sufficient to bring about 
destructive inflammation.”

of cotton seed as a food. 
From the number of cattle that have arrived at the stock 
yards from the South, weak and blind and suffering with acute 
symptoms, it would appear that many feeders are not familiar 
with deleterious results from injudicious feeding, and in con-
