the bark pukes, or purges, or opprefles the ftomach, it is to be coun- 
teracted by remedies particularly appropriated to them. Thus 
vomiting, is often restrained by exhibiting it in wine y loofenefs, by 
combining it with opium; and opprefhon at the ftomach, by the ad- 
dition of an aromatic. But unlefs for obviating particular occur- 
rences, it is more fuccefsful when exhibited in its fimple ftate than, 
with any addition.. 
It may be given from the very commencement of the difeafe with- 
out any previous evacuations, though it commonly anfwers better 
after emptying the alimentary canal, particularly the ftomach ; and 
it is to be continued not only till the paroxyfms ceafe, but till the 
natural appetite, strength, and completion return*. 
In remittent fevers, efpecially during the times of remiffion* the 
bark may alfo be employed with great fuccefs; for as both thefeand 
intermittents arife from the fame caufe, prevail at the fame feafons^

affinity, and found a prefumption which is confirmed by experi- 
ence, that they may be cured by the fame remedy. In continued 
levers, or typhus of the nervous and putrid kind, the bark is very 
generally ufed, as well fuited to counteract the debility or putrefcency 
which marks the progrefs of the diforder. There is, however, one 
irate not unfrequently prefent in thefe epidemic fevers, in which. 
the bark is found to be hurtful; i. e. fymptoms of congeflion, or 
inflammation of the head; manifested by headach, rednefs of 
and phrenitic delirium.. And whenever delirium is ac- 
companied with much fubfultus tendinum, or frequent convulfsve 
twitchings of the limbs, Dr. Cullen thinks opium in large doles is 
the only remedy to which we can trust. 
Of late the bark has been, much employed in acute rbeumatinn,.. 
particularly after the violence of the difeafe has been in fome mea- 
sure moderated by the antiphlogistic treatment, or when evident re- 
miffions take place. Many, however, have recourfe to this medicine* 
in the nrft stage of the difeafe, and we have witneffed its fuccefs in 
fome of the London Hofpitals, even while the inflammatory fymp- 
toms prevailed to a very considerable degree. This feems contrary 
to the experience of Dr. Cullen, who fays,, " As I confider this
