HOMOEOPATHY V. ALLOPATHY.

it generaliy continues through life, as shown in chronic 
dyspepsia, oppression of the chest, or paralytic symptoms.’’ 
It is also notoriously known to both surgeons and veterinary 
surgeons, that arsenic produces great nervous debility , even at 
times so excessive as to give rise to paralysis : from such facts, 
then, together w T ith what I have adduced, I have clearly 
proved that the use of arsenic in thick wind is strictly in 
accordance with the law of similars , and that whatever benefit 
may accrue from its use in such cases, that it is strictly due 
to its operating within the sphere of the said law. 
Iodine is another remedy which I prescribe for thick wind ; 
the physiological action of which is thoroughly homoeopathic 
to the affection arising from the causes to which I allude. 
With reference to the action of iodide of potassium, Dr. 
Laurie, of Glasgow, in the c London Medical Gazette 9 for 
July, 1840, says : 
“ The mucous membranes of the eyes and air-passages are 
especially liable to become affected ; in one instance, the em- 
ployment of the medicine was followed by dyspnoea and loss 
of voice.” “In a third case by fatal dj^spnoea; in a fifth by 
sore throat, acute dyspnoea , and hoarseness, with fatal result.” 
Perhaps I may be told that iodide of potassium is not iodine, 
but then as answer to this I have the authority of my oppo- 
nent for saying that “iodide of potassium closely resembles 
iodine in its actions and uses. # 
Again, Jahr, in his ‘Materia Medica,’ gives the symptoms 
of a case of poisoning with iodine where there was “ violent 
difficulty of breathing, which remained for a fortnight.” 
“ Cinchona does not cause, in the great majority of cases, 
any symptoms at all analogous to fever, and never produces 
the intermittent fever which characterises ague.” 
In the above quotation, we have two distinct affirmations, 
the one is, that cinchona does not in the great majority of 
cases, produce any symptoms at all analogous to fever, and 
the other is, that it “ never produces the intermittent fever 
which characterises ague.” In answer to the first affirma- 
tion, a single line from 6 Pereira’s Materia Medica,’ p. 1404, 
w T ill settle that : “ Cinchona produces,” says he, “ a febrile 
state of the system.” 
Before proceeding to the latter affirmation, it may be as 
well to know what are the peculiarities in connection with 
ague by which cinchona holds so distinguished a rank as a 
curative agent. Ague is a disease which, when fully de- 
veloped, according to medical writers, consists of a three-fold 
character. It presents what are called the cold, the hot, and
