however, without a few remarks touching upon the latter 
portion of what I have quoted from Mr. Dun’s book. 
Mr. Dun says that oil of turpentine destroys, but does not 
produce worms ; that sulphur removes lice and many skin 
diseases, “but does not produce either.” That “arsenic, 
iodine, and belladonna, are homoeopathic remedies for thick 
wind; yet none of these, not even all of them together, 
produce thick wind.” That neither aurum, arsenicum, nor 
bromine, though given for glanders and farcy, “yet none of 
these, nor any other medicine, is known to cause any such 
complaints ;” and that cinchona, though it cures, does not 
produce ague. Now Mr. Dun might have saved himself the 
trouble of writing such a farago of stuff as this ; — no one says 
that these several medicines will produce any of these several 
diseases. The fallacy rests entirely with himself ; he, in 
short, has drawn upon his imagination for facts ; and it is 
certainly too bad to palm such a mass of absurd crudities 
either upon Hahnemann or his disciples, as the parent 
thereof. Again, Mr. Dun makes mention of certain experi- 
ments which have been performed at the EdinburghVeterinary 
College with the homoeopathic system: what these experiments 
were I have no knowledge whatever; but what the results 
would be, if such experiments were performed by any one 
understanding homoeopathy as Mr. Dun understands it, 
would not, I feel assured, be very difficult to foretel. 
Such of your readers, Mr. Editor, as may really desire 
to know what are the pathogenetic effects of the above-named 
medicines, I would refer to c Jahr’s New Manual, or 
Symptomen Codex or, if they specially desire to understand 
the pathogenetic effects of aconite only, they must consult a 
w T ork entitled, 4 The Hahnemann Materia Medica.’* In this 
latter work is contained the best and the most copious 
proving of this drug ever presented to the medical world. 
I remain. Sir, 
Sincerely yours, &c.

Sir, — In September last I left this place (Dalkeith) leaving
