M. Goese, in his admirable essay, Hist. Nat. des Vers Intestin. des 
AnimauXj written several years afterwards, denominated this spe¬ 
cies Les Vers de Camper. 
I lost no time,” he continues, ‘‘ in stating in the public papers 
a discovery so important for the country, inviting co-operation in 
my labours, and volunteering to come and examine the disease in 
any district where it might break out. If ever any cases should 
again occur under my control, I should direct the animals to be 
shut up in huts made for the purpose, where, by continual fumi¬ 
gations, they should breathe a medicated air. The subject is im¬ 
portant, not to my native country only, but to Europe; and I 
would invite all naturalists not merely to examine the nature of 
the disease, but also to inquire into the most effectual and least 
expensive remedies. I cannot reflect upon the benevolent and 
humane disposition now so prevalent, without experiencing the 
liveliest delight, that there nowhere exists the people who will 
not, free from all petty national interest, take their share in this 
great object, which alike concerns us all.” 
To Camper, therefore, belongs the merit of having ascertained 
the cause of this destructive disease. It is fortunate that an effec¬ 
tual and specific remedy has been found out, which has not only for 
its greatest recommendation its efficiency, but likewise its cheapness 
too; for, from the small value of a calf, it would be impossible for 
the farmer to adopt any expensive remedial means, much more 
employ the attendance of a veterinary surgeon: the first loss would 
be the least. It is very singular that this disease should be met 
with in calves that have never been turned out, and during the pe¬ 
riod they are sucking. I give not this upon my own authority, 
hut that of others. It tends, I think, to confirm the opinion ad¬ 
vanced in The Veterinarian by myself, vol. viii, p. 399, that 
it dates its origin from ova taken up in the water the animals drink. 
If the proximate elements of medicine taken in by the mother can 
go the round of her circulatory system, enter into the milk secreted 
by her breats, and affect the offspring that sucks that milk similarly 
to herself, I see no reason why the ova of animalcLda taken up by 
the mother in the water she drinks should not pass into the same 
secretion, be sucked in by her offspring, carried into the round of 
its circulation, and find its way into the bronchi through the me¬ 
dium of its secreted fluids; then become developed, and there give 
origin to this very peculiar aflection. 
The farmer whose young stock I gave you the history of in the 
7th vol. of The Veterinarian, page 585, and who lost six of 
them before we adopted the use of the lime-water and solution 
of salt, and none afterwards, has since had his stock affected again; 
but, by employing these two simple remedies, he cured all in the 
VOL. XIII. H h
