 should be securely nailed to the tray so that the muscles 

 are made tense. When the parts become dry, they

 of 5% ammonium hydrate should be poured over the 

 specimen. 



The muscles of the following table are arranged accord-

 order named. Some classes having time for the study 

 of one-half or even one-third of the muscles here de- 

 scribed will be able by the use of the table and the illus- 

 trations to become familiar with the functions and the 

 relations of any muscles the instructor may wish to 

 assign for study. The student should note carefully the 

 muscles which together effect a certain motion, such as 

 the flexion of the forearm or the extension of the digits.
