Sdlj', mucous matter, which appears to be held in solution by the 

 carbonate of potash ; 4thly, probably a little albumine; 5thly, in the 

 human saliva, a fotty matter containing phosphorus ; 6th]y, soluble 

 salts, consisting of acetate of potash, the presence of which, how- 

 ever, cannot be ascertained by any direct means, but only by in- 

 cineration ; carbonate of potash, which in the sheep occasions the 

 saUva to effervesce with acids ; it is probably in the state of bicar- 

 bonate. The saliva of the sheep contains it in the greatest quantity ; 

 then that of the dog, and lastly, human saliva ; phosphate of potash, 

 in the greatest quantity in man and the sheep, and least in the dog; 

 sulphate of potash, which exists in the three kinds of saliva in very 

 small quantity ; muriate of potash, an alkaline sulphocyanuret, there 

 is most of it in human saliva, a very small portion in that of the 

 sheep and dog's saliva is probably free from it ; the muriate in man 

 is almost entirely that of potash ; in the dog and sheep it is muriate 

 of soda, with very little muriate of potash ; the contents of the sa- 

 liva insoluble in water are phosphate of lime, less carbonate of lime, 

 and very little carbonate of magnesia. — Ann. de Chim. et de Phys.
