114 GENERAL ANALYSIS. 



to fatten, and the five will collectively be better than 

 either separately. 



420. BY GELATIN is meant animal, not vegetable, 

 gelatin. It is merely to be dissolved, when it is ready to 

 pass into the Blood. 



421. SUGAR needs only to be dissolved, when it is 

 ready to pass into the Blood, of which it is an element. 



422. GUM is a kind of sugar (not spruce gum and 

 the like, which are very unhealthy), and very readily con- 

 verted into it, or it may pass into the Blood by simply 

 being dissolved. 



423. STARCH is IN THE FORM of grains, too large to 

 pass into the Blood, and, if it could, would obstruct the 

 circulation in the minute tubes. 



424. STARCH MUST BE CHANGED INTO SUGAR, and as 

 the chemist can in various ways effect the change, it 

 would not be astonishing if the same could be done in 

 the body. 



425. IT WOULD NOT BE LIKELY that the same fluids 

 adapted to dissolve out the Waste substance and leave 

 the Nutritive and Calorific food, would be sufficient to 

 change the Starch. 



426. FAT ALSO, THOUGH A COMPONENT OP THE 

 BLOOD, cannot pass into it till an emulsion has been 

 made of it and some other fluid. 



427. Two MORE FLUIDS at least must be supplied 

 to the digestory process, one on account of Starch, and 

 another on account of Fat. 



428. IT WOULD BE ADVISABLE NOT to have these sup- 

 plied till the process of solution and separation had to a 

 degree taken place. 



429. ANOTHER RECEPTACLE MUST BE ADDED to the 

 stomach to receive its contents when they have passed 

 through the changes necessary there, and the two fluids 

 must be at once supplied. (17, Fig. 100.)
