ON THE SALIVARY GLANDS. 
functions requiring them,—mastication and gustation. From this 
it is evident, that the uses of such salivary glands as are to be 
found in birds can have relation but to the sole existing func¬ 
tion, that of deglutition; and that the viscous, tenacious secretion 
furnished by their glands, partakes of nothing in common with 
the parotidean and submaxillary secretions; but, on the contrary, 
resembles in every respect the fluid secreted by the sublingual 
and buccal glands in mammifera. 
The different salivary glands, having each of them a special 
part to perform, are not calculated to compensate or become 
substitute one for the other. Whenever a salivary gland be¬ 
comes augmented or diminished or annihilated, the function 
depending upon it undergoes correspondent changes. 
In mammiferous animals, who masticate hard and dry sub¬ 
stances, the parotids attain their maximum of development; 
whilst in those animals who inhabit the water and live upon 
humid food, this gland becomes atrophied, or even altogether 
disappears; although there are cases in which the other sali¬ 
vary glands preserve their normal development, corresponding 
to the function they are intended to serve. Lastly, this natural 
deduction has led me to examine into an assertion set forth in 
treatises on comparative anatomy, to the effect that in the mullet 
(surmulei) the sublingual gland is wanting, and has its place 
supplied by the submaxillary. The sublingual gland of the 
mullet has a perfectly distinct existence, as I have represented 
in my drawings. Thus becomes corrected an anatomical error, 
while confirmation is added to the utility of physiological notions 
to the development of which this paper has been consecrated.
