 have been determined bj^ formulas 25 and (25 a).

 These glands are easily isolated on account of their definite 

 outline as well as their tough texture. Two or more lymphatic 

 nodules are found beside the submaxillaries. These are to be 

 excluded and are easily removed with sharp scissors. The graph 

 in chart 41 and the values in table 147 have been determined by 

 formula (26). Hatai '18.
