fenfibility and delicacy of frame have been confidered as the 

 predifponent ciufes, and predominant acidity in the ftomach and 

 intfcftinal canal, as the occafion of almoft all their complaints. 



Reasoning in this manner, a fn'ori, we fliould exped in the 

 cure of their difeafes the pradice to be fimple and the event 

 fuccefsful. In the adult Hate \vc know that there are few 

 morbid caufes lefs noxious to the human frame than acidity, 

 and few more fubjed to the controul of medicine. A little 

 experience and refledion fhould, in my opinion, be fufEcient 

 to convince an unprejudiced mind that the mortality of infants 

 is much greater than could reafonably be cxpedcd, if the preceding 

 theory, with regard to the exciting caufes of their difeafes, were 

 well founded. 



The four following propofitions will be found to contain the 

 fubftance of the opinions of medical writers on this fubjed. 



ift. That human milk is a chylous fluid, and readily afFeded 

 by the kind of nourifhment which nurfes make ufe of. 



2d, That it is coagulated in the ftomach of infants, and that 

 it is coagulable by acids, ardent fpirits, and other known 

 coagula. 



3d, That it is very prone to run into an acefcent or acid 

 ftate.
