DISEASES OE HORSES IN INDIA. 117

pany^s stud at Haupper, of which the following is an extract: 
—There is no question of the fact Dr. Hardtman mentioned 
to you before, of the frequent existence of similar worms in the 
inside of the horse to those which are found in the eye, and 
which are seen alive and moving under the cellular mem¬ 
brane in different parts of the abdomen. I was myself often 
present during the dissection, and saw the worms as above de¬ 
scribed.’’ 
Referring to the Systema Naturae of Linnaeus, I find the Fila- 
ria described thus :—Corpus teres filiforme, aequale, ore dila- 
tato, labio subrotundo concavo.” Filaria equi, habitat in 
equini corporis cavis variis, telaque cellulosa.” 
In Sir Everard Home’s Lectures on Comparative Anatomy, 
he says, the arteries of the ciliary processes in the horse are 
very large; and he is led to believe, that the two species of 
worm, the Strongylus ArmaUis, and Filiaris Papillosa^ found 
alive in the aqueous humour in that animal in India, get there 
through these arterial branches, more especially as they are 
known to exist in the circulating blood of that quadruped.” 
Before this statement of Sir Everard Home, I was not aware 
that the Strongylus had been found in the eye of the horse. 
Under the head Strongylus, in the edition of Linnaeus to which 
I allude, is this remark :—S', eqainus, Capite opaco, intestine 
nigro. Strongyli ovipari, hactenus non nisi in mammalium ca- 
nali Cibario reperti.” 
In the arguments which I have advanced it is not contended 
that every horse having a worm in the eye must of necessity be 
affected with weakness of loins ,* nor that debility of the loins 
arises from no other causes than the presence of worms in the 
interstices of the lumbar muscles and behind the peritoneum. 
On the contrary, Mr. Mooreroft, it would appear, has found an 
accumulation of serum in the spinal theca of horses having par¬ 
tial paralysis ; and probably other causes of the paralytic affec¬ 
tion may exist. If we could ascertain that the Filaria exist in 
the canal of the spine, the information we solicit in regard to 
one cause of weakness of the loins would be attained. 
The manner in which worms may be generated, or their ova 
arrive at those parts of the flesh or viscera of living animals 
where we find the worms, is also an interesting object of in¬ 
quiry, and investigations on this point may be instituted in a 
variety of animals as well as man. Among animals may be 
enumerated, the sheep, deer, horse, hog, hare, falcon, bat, 
bream, herring, sepia lotigo, and frog. Sir Astley Cooper has 
also found a living worm in the coeliac artery of the ass, when
