WILLIAM SMITH : HIS MAPS AND MEMOIRS 
with my own, with the exception that in the former the plates are 
engraved with the numbers, viz. : — 
Mastodon Tooth is Tab. 1. 
London Clay is Tab. 2. 
Craig is T. 2 [error]. 
Upper Chalk is Tab. 3 [error]. 
In the London copy the covers are fortunately preserved, and each 
one is dated. Part I. besides title and 2 pages of Introduction, con- 
tains 8 pages and the above-mentioned four plates. 
Part II. issued on October 1st, 1816 ; pp. 9-16, and 5 plates. 
Part III. [date torn oS, but from the advertisement on Part IV., 
was evidently September 1, 1817] ; pp. 17-24 and 5 plates. 
Part IV., is merely dated " 1819," and contains pp. 25-32 and 5 
plates. 
On Part IV. it is stated that the work is "To be comprised in 
Seven numbers, 7s. 6d. each " ; but apparently no more were issued. 
Probably the delay in the publication (it took three years to publish 
four parts) was partly responsible.
