 does not occur above once in forty or fifty times to be confidered 

 as a morbid deviation from the healthy ftandard ?

 becaufe it is readily deteded by a watery infufion of the ftomachs 

 of ruminating, and of fome non-ruminant animals, by acids, by 

 ardent fpirits, and by the juices of certain plants, and becaufe 

 by the admixture of thefe we are enabled to colledl a quantity 

 of vifcid matter, which when expofed to prefTure is well known

 have arifen the general opinion. But furely fuch defcriptions 

 would have been more accurate had they been thus flated, 

 " infants often throw up quantities of a foft vifcid matter

 " a good deal of turbid whey-like fluid." 



It appears to me furprizing that Dr. Young was not able

 artificial means were fufficient to feparate a curd from woman's 

 milk ; " yet," fays he, " this feparation takes place fpontaneoufly, 

 " efpecially if it be placed in a fituation equal to 96° of Farenheit's 

 " thermometer, and it is daily obferved in the milk which
