and water, barley-water, gum arabic water, mu- 
cilaginous fluids as decoction of mallows, infusions 
of slippery elm-bark, flaxseed tea, Ac. or some 
diuretic ptisans: as water-melon seed tea, parsley 
root tea; tea of carrot-seeds, scabious and the like. 
- Incases which admit of delay, the head should 
be shaved six, eight or ten hours before the appli- 
cation of the vesicatory, and the chance of strang- 
ury may be further lessened, by removal of the 
blister after it has risen, washing the part with 
some bland fluid as milk and water or cdagiains 
ointment and reapplying it. This may in partic- 
ular cases, be done even in an hour or two, when 
it has acted as a rubefacient, and in instances of 
excessive pain, it may be altogether removed at 
this time and an emollient poultice substituted. 
_ Twelve hours is the time usually allotted for the 
continuance of blisters on any part of the 
except the head, on which they are allowed to re- 
main double that time. I really think there are 
numerous cases in which all the beneficial effects 
of the vesicating stimulus may be obtained in six 
or eight hours, particularly on the sensitive cuti- 
cle of infants and young persons. To me it ap- 
pears that when the former have continued a half 
an hour to complain by word or action, of the 
pain, afurther continuance of it may be saved by a 
removal of the cause. Notwithstanding this how- 
ever, it does sometimes happen, that both with 
children and adults, a time exceeding that already 
ee sa Sts 
specified, as the usual period of their application 
must be allowed, to obtain all the benefit desired. 
‘To know when this is proper must be the result of 
observation of the case under immediate treatment.
