ON THE SECRETION OF SALIVA. 
143 
In this experiment, we may take as normal the first three samples of'saliva secreted 
under the influence of pilocarpin, before the solution of salts was iujected, and compare 
with these the saliva secreted after the injection of salts. Samples X. and XII. we 
omit from the following Table, and consider them later p. 147), since we think that 
the percentage of salts in these was largely influenced by the considerable dose of 
pilocarpin given.

Remarks. 
Normal. 
Immediately after injecting 50 c.c. 
19 p. c. salts ; percentage of salts 
ill IV. much above normal. 
Percentage of salts in V. slightly 
higher than normal. 
Percentage of salts in VI. above 
normal. 
Percentage of salts in VII. above 
normal, and more so than in VI. 
Immediately after injecting 50 c.c. 
19 p. c. salts ; percentage of salts 
in VIII. above normal, but less 
so than in VII. 
Percentage of salts in IX. slightly 
above normal. 
Percentage of salts in XI. normal, 
or nearly so. 
It will be seen from the above Table that, of the tliree rapid secretions obtained 
after the injection of salts into the blood (V., IX., XL), two (V. and IX.) have 
apparently a slightly higher percentage of salts than normal. 
The slower secretions (IV., VI., VII., VIII.) have all a higher joercentage of salts 
than normal, and this is very marked in IV., which was taken soon after injecting 
salts into the blood. 
That is to say, ivith an increase of salts in the blood ivhich leaves the secre¬ 
tory 2 )oiver of the gland unaffected, the jgercentage of salts is relatively 
more increased ivith slowly secreted than ivith rapidly secreted saliva.
