wide enough to admit fo grofs a Body as t9/^//e4///e, vrc, 
may here in part exphin the admiffion of Liquors, (as of 
Diuretic waters, d^c.) into the Veflels in frodigious qna»* 
titles^ in a very little time. 
The lame widenefs of the PjU l^aBe^^ makes them 
eafy to receive (together with proper Vehicles) thofe 
groffer Bodies, which afterwaads compofe the grumofe 
part of the Blood, the Cartilages and Bones. 
And this open entrance being allow *d, it will no long- 
er feem impoffible, that with our nourilhment. Eggs or 
Animalcula themfelves, (hould enter thefe VelTds, there 
being no manner of Queftion, but that of both the one 
and the other^ fome are much kfs in bulk, than the 
greateft Particles ot Indigo, in the Decodtion above- 
mentioned feen in the Lafteals. 
Add to this the many (pecies there are of little In- 
feft.% and their great Fertility ^ fo many and fogrcat,that 
of the People of the Animal Kingdom, a very fmall 
proportion (perhaps not a quarter part) comes within 
view of the naked Eye ^ and tiien, we fhall be the 
better able to account, lor the great variety, as well as 
numbers of Infefts, obferved in the Juices ot the Body 
Animal. 
/ But the chiefeft ufe of the widenefs of the Lafteal Ori- 
fices, is in deducing from thence the reception of grofs 
matters (fuch as are the effefts of indigeftion, d^r. J)'Which 
afterwards in the Blood and Genus Nervofum^ many times 
produce moft fevere Diftempers. 
Which notion being in fome degree confirmed by its 
firft propofer (We Clurijf. Lijieri de tontibus medicatis 
Anglic exerdtatiGnem alteram^ Ed. Lofid. fag. 48.) will, 
belt of all, receive farther Illuftration from the fame hand. 
The . Foundation he builds on is certainly good, and we 
have .reafon to hope the Superftrufture will be fuch 
alfo.
