The present Memoir forms the Supplementary Report promised at that 

 time on a number of forms which reached Professor Hertwig too late for the 

 descriptions to be included in the original Report. It consists of 56 pages 

 of letterpress and 4 lithographic plates. 



The Memoir was translated from the German by G. Herbert Fowler, 

 Esq., Ph.D., of University College, London.
