each  word  must  have,  in  addition  to  definition,  some  indication  of 
its  relationship  to  various  departments  of  medicine.  The  result  has 
been  a  work  which  has  proven  to  be  almost  indispensable  to  students 
and  practitioners.    In  the  present  edition  numerous  illustrations
