EMANATIONS FKOM MEDICINES. 99 



feet health, with results differing from the abova no more 

 than what might easily be accounted for by the different de- 

 grees of susceptibility in the experimenters. The different 

 substances tried are enumerated by Reichenbach according to 

 their specific effects, but it will here be sufficient to say that 

 sulphur was found to be the general representative of those 

 which, without contact, gave the sensation of cold, and gold 

 of those which gave warmth ; and almost every one whose 

 hand was made to pass over small plates, coated respectively 

 with these substances, felt, in some degree, these correspond- 

 ing sensations, and some felt them quite vividly. 



Without any knowledge of Eeichenbach's investigations, 

 Dr. G. R. Buchanan, of Cincinnati, was engaged, about the 

 same time, in a similar course of experiments with amorphous 

 bodies, and developed results similar in-character, but in some 

 respects even still more decisive. Without here entering into 

 the details of his experiments or inquiries, it will be sufficient 

 to state that they resulted in establishing the fact, that 

 medicines, holden in the hand of the patient, even when 

 wrapped up in paper and concealed from view so as to guard 

 against the effects of imagination, will, in a large proportion of 

 cases, have all the effects that the same medicines will have, 

 taken internally. Out of about one hundred and thirty 

 medical students belonging to a class which attended the 

 lectures of Dr. Buchanan, forty-three declared themselves 

 fully affected by this experiment, to which they had been sub- 

 jected during the delivery of one lecture.* 



Similar phenomena have been observed as the results of 

 similar experiments in other instances, but we have no room 

 for further details on this branch of our subject. In all such
