282 PHYSIOLOGY OF THE DOMESTIC ANIMALS. 



The secretion of the submaxillary glands is not unilateral, as in 

 the case of the parotid, and the side on which the greatest secretion is 

 taking place does not appear to be modified to any great extent by the 

 locality of mastication. The largest amount of submaxillary saliva is 

 secreted at the commencement of a meal and almost ceases during ab- 

 stinence,; — a point of contrast -with the parotid saliva. The stimulation 

 pf the sense of taste by sapid substances is of the greatest influence on 

 the amount of submaxillary saliva. The following table, compiled by 

 Colin, illustrates these facts : —
