in the mouth of a hungry perfon: certain ideas excited in the mind 
are the occafion of a flow of tears from the lachrymal veflels : and 
the breaft of a nurfe begins to give milk when a child is brought 
only near it. The extraordinary motions of the veflels of thofe 
parts cannot in any other way be Recounted for, than by aferibing 
them to the mind $ of whofe aélion, however, we are no ways con- 
Further, fince, in confequence of certain ideas being excited 
in the mind, the flomach is immediately affedled with a naufea and 
vomiting, it cannot be denied that this is owing to an increafed 
action of the nervous influence, by means of the mind, upon the 
mufcular fibres of this organ ; yet we are not more fenfihle of an 
exertion of the mind in this cafe, than we are when vomiting is ex¬ 
cited by a dofe of ipecacuanha or emetic tartar. The want of con- 
feioufnefs, therefore, can be no good argument againfl the motion 
of the flomach, whether natural or perverted, being produced by 
the adtlve power or energy of the fendent principle, which is va~ 
rioufly affedied by the different ßiniuli applied to the delicate nerves 
of that organ ; and if the idea, only, of a difagreeable fenfation in 
the flomach can occafion, through the influence of the mind, the 
motions of vomiting, why fhould not the real fenfation in it more 
remarkably affedl the mind, and fo excite it to produce the fame 
motions ? 
What has been faid with regard to the motions of the flomach, 
may readily be applied to thofe of the heart : for no fooner are cer¬ 
tain ideas prefented to the mind, than the motion of the heart is in¬ 
creafed and accelerated ; which muft, therefore, I fhould think, be 
the effedl of an extraordinary a&ion of the nervous power on its 
fibres confequent upon the emotion raffed in the foul : yet of this 
effort of the mind we are not in any degree confcious. If, there¬ 
fore, the mind can thus influence the motion of the heart, whilfl 
we are not fenfible of its power being directed to that end, it feems 
not unreafonable to fuppofe, that theßimulus of the returning blood 
may excite the fentient principle to bring the heart into contraction, 
although we are not confcious of any fuch exertion of its power.
