HI! PREFACE. 



to request a continuance of those communications from scientific investi- 

 gators, which have hitherto so materially aided him. 



The woodcut illustrations which accompany the Anatomist's Vade 

 Mecum have been increased with each edition. Several of the new 

 figures are illustrative of General Anatomy, and, to insure their absolute 

 correctness, have been drawn from the microscope by the Author himself, 

 with the aid of the camera lucida. Figures 13, 14, 15, showing the 

 changes which occur during the development of bone ; figures 63-66, the 

 minute anatomy of cartilage; and figure 103, the structure of the ultimate 

 muscular fibril, are examples of such drawings. The structure exhibited 

 in the latter figure formed the subject of a paper which was read before 

 the Royal Society during the present year.
