singly,-it must have been when the disease was appropriate to it 
alone, and different from that which another has cured. Con- 
sequently, those fevers which are cured by different remedies 
must be different from each other, as well as the remedies 
themselves, which cannot therefore be considered equivalent, or 
capable of taking place of each other. 
“ Nature is far more various in the properties with which she 
has endowed medicines, than the compilers of Materia Medica 
have imagined. Also, she is infinitely more varied in the diver- 
sities she causes in the human system, than pathologists are 
aware of in the few dozen forms of diseases, of which even 
they cannot make a faithful picture. 
“Tt would signify little that in mixing, as they do, Quinine 
and Iron together, physicians produce a mixture of disagreeable 
appearance and taste, which is like ink; but they must be told 
that the result is a substance, possessing neither the virtues of 
bark nor of iron. This is because iron sometimes acts as an 
antidote in cases where Quinine has been injurious; while 
Quinine has put a stop to effects caused by iron wrongly given. 
“Tron, however, can only destroy a part of the hurtful pro- 
perties of Quinine, such as have analogy to the symptoms caused 
by the former in a healthy person. 
“ After long treatment, in which large doses of Quinine have 
been given, many inconveniences often remain, which require 
other medicines. Very often, these Quinine diseases are carried 
to such a degree of exasperation, that it is difficult to free the 
sufferer from them, and snatch him from death. In such cases, 
ipecacuanha, more frequently arnica, and sometimes belladonna 
are given, according to the nature of the symptoms. Veratrum 
album is suitable, when Quinine has caused chilliness of the 
body, with cold sweats, provided there is also accordance be- 
tween the symptoms of the disease and those of the medicine.”
