By that the Blood -Vefl*els, didended beyond Mea- 
fure, are evacuated and reduced to their ufual Dia- 
meter. As to both thefe Means of Cure, we mud 
be particularly cautious that the Patient have dill 
Strength enough to bear them ; otherwife perhaps 
the Remedy might be worfe than the Difeafe. Af- 
terwards, acid Draughts are to be given, made of 
the Juices of Citrons, Oranges, Currants, Vinegar, 
Spirit of Sulphur, or Vitriol: For they hinder the 
Expanfion of the Sulphurs, redrain their Force, 
and thicken the rarefied Blood. Acrid dimulat- 
ing Clyders are to be injected, Powders blown up 
the Nodrils made of Pellitory or Euphorbium, and 
volatile Salts may be taken inwardly. Biidering 
Plaiders and Sinapifms are advantageoufly applied 
to the Neck and the Soles of the Feet ; alfo Cup- 
ping Glades, Scarifications, Burnings, painful Fric- 
tions, &V. are ufed with Succefs. For by thefe 
dimulating Remedies the nervous Membranes are 
drongly vellicated, the Spirits are derived more 
abundantly to the Parts, which thence recover their 
Tone, the Fluids of the renal Du6ts, being more 
forcibly p reded, break forth where they find a 
Padage, and the Secretions and Excretions are re- 
do red. 
With Regard to the Operation of Biidering Plan- 
ters in the Deliriums occafioned by Opium, Alexander 
\ Thomfon , an Englijh Phyfician, in his Medical Dif- 
fertations on Opium , obferves, that when the Patient, 
during the fird Operation of the Plaider, complains 
of a Coldnefs falling from the fore Part of his 
Head down his Neck, he is immediately freed from 
the Delirium. This, certainly, is a great Argument 
that the Brain, by Means of the Stimulus commu- 
nicated from the Plaider to its nervous Compages , is 
unloaded of a fuperfluous Quantity of Liquid : 
Whence a Solution of the Delirium.
