presence of the salt, in concentrations up to 2 per cent., greatly in- 
creased the amylolytic action of saliva. 
Our results with different percentages are as follows:

0 0°1660 gram. 0°3392 gram. 30°52 per cent.

These accord with the results mentioned above and show, more- 
over, that with 5:0 per cent. of the salt, hindering action just com- 
mences. Increasing the amount of salt beyond this point, however, 
only slowly diminishes the action of the ferment; thus, in the pres- 
ence of 10:0 per cent. of the salt, 22°78 per cent. of starch was con- 
verted into sugar, while without it 25°20 per cent. of starch was 
converted. 
Morphine sulphate. 
With this alkaloid O. Nasse* has experimented, using, however, 
the acetate. He found that the presence of 0:1 per cent. of the salt 
caused a slight increase in the diastatic action of saliva (109: 100).

The stimulating action of the alkaloid salt up to 2°0 per cent. is 
very apparent. 
Quinine sulphate. 
With the acetate of this alkaloid, Nasse found, by the use of 0:1 
per cent., an increase in the starch-converting power of the saliva 
(115: 100). With the sulphate we obtained the following results :
