10 b show an embryo and a fetus with hare lip. Figure 11, 12 

 and 13 have pronounced localized anomalies and need no further 

 explanation. Finally figures 14 to 18 show anomalies of the 

 hand the first and last are of the hereditary variety, and figures 

 15 and 16 show acquired anomalies, that is, they were subse- 

 quentl}^ formed in an embryo which started its development 

 normally. It is proper to remark here that these illustrations 

 are mostly from specimens from the second thousand of our

In order to render possible a comparison between localized 

 anomalies found in pathological and those found in normal em- 

 bryos, the following six tables have been constructed. Table
