Among the more modern nbblicatiónis that of M. Pallas unquef- 
tionably holds. a diftinguifhed rank. His Thefis de infiftis viventibus. 
inira viventia; printed at Leyden in 1760, is an elaborate difquifition 
on this fubje&, and is worthy of being particularly noticed, as con- 
“taining not only very complete defcriptions and fpecific differences 
of worms infefting the body of man, but alfo a colle&ted feries of the 
moft ufeful knowledge of preceding nens with the various modos 
of extirpating thefe pernicious inmates. 
_ To the almoft unparalleled induftry of Otto Frederic Müller the 
greateft merit is due, for his accurate defcription of the Helminthic | 
order : and, probably, we owe to the Royal Society of Copenhagen, 
two publications which have fince fo much extended the knowledge: 
ofthe prefent day, on thefubject of my paper. The Premium, of 
which I give the title below *, held forth by this Society, excited 
„the diligence of M. Bloch of Berlin, and M, Goeze, to both of whom. 
prizes were affigned. M. Bloch publithed his Differtation, which was 
tranflated into French, under the title below recited +; the latter 
publifhed a Defcription of the fame animals, in quarto, f. 471. in the. 
German language, with 44 plates. Gmelin, in his enlarged edition. 
of the Syfema Nature, has enumerated. feventy-eight fpecies of. 
Afcarides, having arranged them. according | to gihe ci dalfe; of animals. 
in which they exit; of which, twenty- four fpecies 
found to be infefted with thefe worms. Thofe y now s Tend are an. 
addition to that number. M. Goeze alone, from references to his. 
work in Gmelin, appears to have defcribed upwards. of twenty.
