sediments, and, on the other, into undoubted eruptive 

 material. After spending some time on Caer Caradoc 

 and Hope Bowdler he went to Bishop s Castle, and 

 on the first day of the stay there makes the following 

 entry : ist October. Went out to take a turn on the 

 traps and altered rocks at Upper Hublast (sic). Found 

 that they had been injected into and highly baked the 

 Wenlock shales, and in one place, as I thought, fairly 

 melted them, so that part of this must be mapped trap. 

 Forbes and I had a tough argument on this head, for 

 I fancied I could trace a gradual change from the 

 genuine baked Wenlocks into melted beds. This he 

 would not allow, so we both became hot, and neither 

 gave in. We were doubtless partly both right.

 able to walk, he seems to have consoled himself by
