in bulk in Mark Lane, 1 of course accompanied him, 

 the fossils and sands and clays going, as we can 

 believe, without regret on the part of the worthy old 

 housekeeper. Civil Prestwich was ten years younger 

 than her brother, and they had a joint home until 

 her death in 1866. She at once became his secretary 

 and amanuensis, devoting her whole time to the fur- 

 therance of his scientific work, freeing his mind and 

 time from all the wear and tear of petty distractions. 

 He was eminently domestic : instead of the solitary 

 City sitting-room and that daily Spartan fare, he had 

 now all the comforts of a happy home. Civil was 

 capable and intelligent, and under our geologist's 

 guidance rough manuscripts were transcribed, registers 

 were kept ; and a folio volume of references which lies 

 open before us is entirely in her handwriting, and is 

 a model of method and order. There are four columns 

 for England, France, Europe, and other parts of the 

 world and the authors quoted imply a wide range of 

 research, although chiefly on Eocene, Miocene, and later 

 Tertiary geology. They include also subjects which 

 were discussed in subsequent writings, such as Raised 

 Beaches, Drift, Boulder Clay, Glacial Action, River 

 Deltas, Wear and Tear of Land, Caves, Temperatures 

 of Mines, &c., and Theoretical and Cosmical Geology.

MY DEAR SIR CHARLES, The question is a difficult one. If 

 Forbes is right in his synchronism of the Hempstead Beds with 

 the Fontainebleau Sands, then I do not see where to draw the 

 line of demarcation between those beds and the Barton Clays.
