A . PREFACE. — 
tity sufficient to remove disease may be introduced into 
the system, whilst at the same time, in topical affections the 
remedy may in this manner be applied over the seat of 
the disease; but when the affection is more general 1m its 
character, the internal use, or both methods combined, 
will be found most advantageous. : 
The author would caution the profession against expect- 
ing too much from the employment of these remedies. In 
some cases they have given only a temporary relief, whilst 
in others they have had no effect: but generally speaking 
he has found them of much more advantage in the treat- 
ment of a very distressing class of affections, than any means 
hitherto discovered, and on this account he would recom- 
mend their use. |
