CHEMISTR Y OF THE DIGESTIVE PROCESSES. 
This table shows the results obtained by \Verther l in four experiments on 
dogs, in which all three kinds of saliva were collected and analysed. The results 
have been placed in a similar form to that of the other tables, for ease of com- 
parison. It should be observed that the sublingual saliva was barely alkaline 
in all four experiments, while the submaxillary saliva was only so in one 
experiment; that the sublingual saliva contains in spite of its viscidity no 
more organic matter than the others, while it does contain much more 
chlorides. Human sublingual saliva has never been obtained in sufficient 
quantity for analysis.

Analyses I. to YI. are of human saliva by Berzelius, Jacubowitsch, Frerichs, 
Tiedemann and Gmelin, Herter, and Hammerbacher respectively. Analysis 
VII. is of dog's saliva by Schmidt. The table is taken from Maly, 3 except 
Analysis VI., which is from Hammerbacher. 4 The analyses of ash are by 
Jacubowitsch. 5 In 1000 parts of the ash of mixed human saliva, Hammer- 
bacher 6 found 457-2 of K.,0, 95-9 of Na 2 0, 50'11 of Fe.,0 3 , T55 of MgO, 
63-8 of S0 3 , 188-48 of P 2 5 ", and 183-5 of chlorine.
