[For preface to the work, written hji Dr. Kmil. Cm:. J/a.\sex, 

 see volume /.] 



Since the publication of the tirst volume of this important 

 work we have been repeatedly asked for the companion 

 volume. The (Jerman publishers have now arranijed to 

 issue the second volume in parts rather than await the 

 completion of the work. Advance sheets have therefore 

 been placeil in our hands, and we are now able to provide 

 English readers with the present instalment, which con- 

 stitutes Part I. of the second volume. 



The concluding portion of tlie volume will follow as soon 

 as the German proofs come to hand. 



January 1903.
