 then as to old localities for the fragments, independ- 

 ently of not having cakes which have been eaten, who

 evidence. He asked Ramsay to go over the ground

 he had been studying in England. Starting with 

 Mrs. Ramsay at the beginning of August, they made 

 their way by Heidelberg to Eisenach, spent some

 narrative has arrived. We have seen how imperfect 

 he knew the maps of South Wales to be, owing to the 

 want of any proper subdivisions among the older 

 Palaeozoic formations. At the time when that ground 

 was mapped the importance of such subdivisions had
