230 ON POULTRY LOUSINESS IN THE HORSE. 
It is notorious among horse-men, that horses who have been 
running out at grass or strawyard all the winter, and come to be 
taken up at the spring of the year with long, dirty, old coats 
upon their backs, and particularly when they are low or starved 
in condition, not infrequently are found lousy. They seem to 
have engendered the lice amid the dirt accumulated upon their 
skins, which somehow or other would appear to be associated with 
the depressed condition and poorness of blood the animal exhibits. 
There is no evidence to shew they are caught from any other 
animal. Indeed, were they the fruit of transmission they would 
not survive, since it is now pretty well ascertained that each spe- 
cies of animal can support but its own peculiar louse. And this 
is a fact which would appear to operate against the transmission 
of the fowls’ lice to horses ; though M. Bouley does not pretend 
to think that such lice sojourn with the horse, but only deposit 
and hatch their eggs upon his coat. And if it be true, as is 
calculated to be the case, that one louse will lay “ nine thousand 
eggs in a couple of months,” we can readily account for their 
numbers, even though it appears certain that they cannot for 
any long time exist in their transplanted condition. 
We again solicit attention to this novel and rather curious 
addition to our pathological catalogue, as offered to our notice 
by our French brethren. Through our Journals and occasional 
communications on paper, we seem as though we had now 
become, in a measure, identified in scientific interests with 
the continental veterinary world, and in particular with the 
French veterinarians ; and we therefore feel it behoves us — 
and we dare vouch for such feeling being reciprocal — to do all in 
our power towards the augmentation of that knoweledge whereby 
we both may be said to “ live and move and have our being.”
