contrary to the experience of Dr. Cullen, ‘who says, “As L.con- 
‘Sider this disease as especially consisting’ in a phlogistic  diathesis, 
J hold the bark to be absolutely improper, and have found it mani- 
festly hurtful, espedialy i in its beginning, and in its truly inflam- 
snatory state.” 
In the confluent small-pox the Eiok has, ian. oan to 
promote the rising of the pustules; this opinion our.own.experi- 
ence teaches us to reject; but after, the maturition of the pustules 
is completed, or whete symptoms of putrescency,. ora, dissolved 
state of the blood supervenes, the bark cannot be too liberally em- 
ployed. The other diseases in which the bark is recommended, are 
gangrenous sore throats, . -and indeed every. Species of gangrene ; 
scarletina, dysentery, all hemorrhages of the passive kind; like- 
‘wise other increased discharges; some cases of dropsy, especially 
when unattended with any particular local affection, .scrophula, ill 
conditioned ulcers, rickets, scurvy, | states of convalescence, certain 
stages of phthisis pulmonalis, &c. 
The officinal preparations of the bark are the powder, the extract, 
the tincture, and the decoction. This last, though frequently em- 
ployed, is in many respects inferior even to.a simple watery in- 
fusion; but’ the best form is that of powder, in which the con- 
Stituent ae are inthe most effectual proportion.
