In the selection of the abbreviations, which here follow the 

 names of the muscles and are used in lettering the figures, while 

 they are, in general, those suitable to the anatomical names, an 

 attempt has been made, where possible, to employ the same letters 

 for corresponding muscles in the two limbs. Thus, in such cases 

 as Pronator, Flexores breves superficiales, etc., both name and 

 abbreviation are the same in both, while in cases like the two 

 Palmares, as compared with the Plantares, the names are suffuc- 

 mently similar to allow the use of identical abbreviations. Far 

 from causing a confusion thereby, it is intended to simplify matters,
