 thereby, as it were, wound up; and although the several

In almost every treatise on the subject of chronical dis- 

 eases, are to be found numerous instances of the benefit 

 produced by the several modes of gestation which have 

 been most generally adopted ; as riding on horseback, i!i 

 carriages, sea-voyages, and swinging. And in many cases 

 which might be adduced, it has appeared too clear to 

 admit of a doubt, that the cure of the patient has been 

 owing Sdleii/ to the external agitation of his body, which 

 must be allowed, at least, to have had the effect above ex- 

 plained ; that of relieving the heart and arteries from a 

 great part of their exertion in propelling the blood, and 

 rnatf theref^jre have coutributcd to the cure, by that means 

 only. 



The different modes above mentioned are adapted from 

 their nature to ditferent degrees of bodily strength ; -and if 

 there are cases in which that which appears most eligible 

 may not suit ihf situation or circumstances of the patient, 

 it cannot be difficult to contrive other means of giving 

 motion, so as least to incommode, and yet to give the 

 greatest relief. A very gentle and long continued, or even 

 incessant motion, may suit some cases better than any 

 more violent and occasional agitation ; and in this way, 

 probably, it is, that sea-vovaG;es have sometimes been at- 

 tended with remarkable advaniai^e.

JL HE opinions of profound theorists are ever entitled to 

 attention ; but sliould not be received with implicit faith. 

 If such a man as Sir Isaac Newton was capable of a mis- 

 take, so is an Emanuel Bach, or a Kollmann. To the latter 

 gentleman the musical world is under the greatest obliga- 

 iiouf for reducing tht theory of Composition to a degree
