thographiec Printing; an art which is at present only 
in its infancy. 
To some of the subjects, that were sufficiently ob- 
vious, I have ventured to affix names, while to 
others, which appeared to be new, and whese cha- 
racteristic marks were doubtful, or undefined, I have 
given none; leaving it rather to those, whe by their 
knowledge and experience, are better able to supply 
the deficiency. 
Having been disappointed in the appearance of 
No. 10, when the plates arrived from the Printer, 
in London, I had determined on withdrawing it, 
and on giving No. 11 in its stead: but, as the 
subject was an interesting one, I considered it best, 
on second thoughts, to retain it, although not equal 
to my expectations. With this remark, that in the 
present stage of the new art of printing from stone, 
there will be sometimes a failure in the working 
off, without any deficiency in the artist; and which, 
in the present instance, as far as regards Mr. Wors- 
ley, who resides at Plymouth, was far from being 
the case.
