AUTHORS’ PREFACE. Vv 
same applies to the selection of examples from anatomy and 
morphology. The one hundred and four illustrations of the 
first edition have, for the most part, been again introduced, al- 
though increased by thirty-seven illustrations sketched by ‘the 
_ newly associated author, as also by a number borrowed from 
other works, the names of which, as a rule, have been men- 
tioned. With some of the Thistrations which were placed at 
our disposal by the publishing house of Springer, it has not 
each time been stated whether these were derived from the 
works of Hager, Hartig, or Méller. Very often we were also 
obliged to content ourselves by referring to still other illustra- 
tions, for example, to the plates of the handsome anatomical 
atlas by Berg. 
Tt has likewise been our endeavor, through abundant cita- 
tions of the literature, to be of service to those members of the 
profession who may desire more complete information. Al 
though not every one will be in a position to refer to the 
sources of information cited by us, we nevertheless wished, on 
the one hand, to show that we have endeavored to utilize the 
best and most recent acquisitions upon the wide field of the 
auxiliary sciences, and, on the other, we hope thereby to afford 
an impulse in many directions. The latter purpose was par- 
ticularly kept in view with regard to the section devoted to the 
history of drugs. Tue Avrnors.
