must be fixed to the binding screws ; thus, if attached to Nos. 4 

 and 3, the least power will be given ; if to 4 and 1, the greatest. 

 The power may be increased or diminished according to the size 

 of the battery, and the strength o f t h e acid used. These instru- 

 ments are readily set in action ; easily cleaned ; very manageable ; 

 and as efficacious as any other form of Voltaic apparatus. To the 

 medical practitioner, their portability is not their least recom- 

 mendation, since they are sold in a neat packing-case, which 

 contains the battery, directors, coil, and all necessary appendages. 

 We have said that there are other forms of this instrument ; 

 but as they differ (with one exception, the Galvano-Therapeuti- 

 con, hereafter described,) only in the mode of breaking the 

 battery contact, we do not deem it necessary to occupy more space 

 in details which, considering that the principles upon which they 

 are constructed are essentially the same, would doubtless be con - 

 sidered tedious. We repeat, that all these machines act in the 

 same way, and depend on the same philosophical principles for 

 their action and efficacy. This is a fact which we are the more 

 disposed to impress strongly on the mind of the medical reader, 

 since we are aware that latterly there have emanated statements 

 in direct opposition to this, from many unprincipled venders of 

 such apparatus, actuated only by mercenary motives. Such 

 groundless assertions are but a part of that spirit of charlatanism 

 which arrests the progress of all great truths, or, with refer- 

 ence to new and important remedies, gives rise to incredulity on 

 the part of those who discover the deceit.

We now come to the latest and most approved arrangement 

 for medical purposes, viz : the Galvano-Therapeuticon of Mr. 

 Charles Brown, jun. of Woolwich. 



This machine bids fair to be far more popular than any of its 

 contemporaries. It is very efficient, perfectly safe, and of such 

 singular facility of management, as to render it, in this respect*
