ceffive Heat, has the fibrous Part clofely compar- 
ed, whilft the other is difTolved into Serum: 
in thefe, I fay, and in Perfons under the like In- 
difpofitions, the Body feems to be overftocked with 
ferous Humours ; infomuch that they fpit often, 
and difcover other Signs of a Superfluity of fuch 
Humours. Yet thefe Temperaments are not to be 
accounted moift ; but, on the contrary, the Fibres 
within are hot, dry, and rigid. For being velli- 
cated and fhrivelled up by the Acrimony of the 
Humours, they exert not their Ofcillations with 
fufhcient Force to carry on the due Circulation 
of the Fluids. Hence they ftagnate in all Parts of 
the Body, and tran fuding through the Vefiels, pro- 
duce Cachexies, cedematous Tumours, Leucophleg- 
macies, Dropfies, and other Affections, which ne- 
ver yield to Hydragogue Medicines of this Sort. 
By a moift Habit of Body we are then to under- 
hand, an Habit replete with foft, mucilaginous, 
chylous, or recrementitious Juices-, in which the 
Moifture is not owing to a diffolving Salt, or a 
Stagnation of the Fluids, but to a Redundancy of 
nutritious juices, to Crudity, or over Feeding. In- 
fants may ferve as Inftances of this Temperament, 
who living upon Milk and Pap, with the like humec- 
ting Aliment, eafily bear purging. Again, Gluttons, 
who having their Blood overcharged with Fat, Chyle, 
or Serum, fupport the Operation of a Cathartick 
without Injury. For this keafon Jalap is very ufe- 
ful in the Difeafes of Infants becaufe all its Acri- 
mony is blunted by the foft, milky or chylous 
Quality of their Fluids: but, on the other Hand, 
the Blood of Adult?, being bilious or too elaftick, 
by a cathartick Medicine like this, is immediately 
thrown into Fermentation. Upon the fame Ac- 
count alfo Purges are more fuccefsful in the acute 
Fevers
