of thefe wonderful animals to be far greater than 
before imagined. 
To the generality of readers, however, a too par¬ 
ticular enumeration of the vifceral vermes, though 
abounding in curiofity, might be unpleafing; and 
it is perhaps one of the few cafes in which an igno¬ 
rance of natural hiftory contributes, in fome degree, 
to our happinefs; fince it mull be allowed that a full 
furvey of the modern difeoveries on this fybjedl ex¬ 
cites ideas unfavourable to our own repofe; nor is it 
pofTible to furvey, without a mixture of horror and 
aftonifhment, the numerous lift of thofe difgufting 
inmates, which, for reafons uninveftigable by human 
wifdom, arc permitted to take up their abode in the 
internal parts of different animals; and which feem, 
fo far as the utmoft refcarch of Naturalifts has been 
capable of difeovering, to be intended for the real 
and proper inhabitants of thofe fituations, being un- 
difcoverable in any other place. As a convincing 
proof of this, it is certain, that in animals recently 
born^ their exiftence has been afeertained; an obfer- 
vation which did not efcape the attention of Hip¬ 
pocrates. 
But to return to the immediate fubjeift of the pre- 
fent paper; of the Ta?niae which infeft the human 
fpecies the moft remarkable are the Taenia vulgaris, 
and the Taenia Solium oi Linnaeus; each of which 
has fometimes been found of an incredible length, 
and produdlive of the moft diftrelling fymptoms.
