they cannot be had, sour small beer, or other similar liquorS, 
may, probably, be used with the same success. The 
quantity of tin used in tinning a definite number of plates, 
each of a definite size, is not the same at different manu- 
factories. In some fabrics in Bohemia , they use 14 
pounds weight of tin for making 300 plates, each of them 
being 11 1-5 inches long by 8 1-2 broad ; according to 
this account, one pound of tin covers a surface of 28 1-3 
square feet : in other, where the tin is laid on thicker, one 
pound will not cover above 22 square feet ; the thickness 
of the tin, even in this case, is small, not much exceed- 
ing the one thousandth part of an inch ; though that is 
near twice the thickness which tin has upon copper in the 
ordinary way of tinning. I have enquired of our English 
manufacturers concerning the quantity of tin used by 
them in covering a definite surface of iron, and from what 
I could collect, it is very nearly the same with that used 
in Bohemia, from whence we derived the art of tinning, 
or 28 square feet to a pound of tin. 
There are various tin plate manufactories established of 
late years in different parts of England and Wales. Sax- 
ony, and part of Bohemia formerly supplied all the known 
world with this commodity ; but England now exports 
large quantities of it to Holland, Flanders, France, Spain, 
Italy, and other places. About the year 1670, Andrew- 
Yarranton (he deserves a statue for the attempt) under- 
took, at the expence of some enterprising persons, a jour- 
ney into Saxony, in order to discover the art of making 
tin plates ; he succeeded to his utmost wishes ; and, on 
his return, several parcels of tin plates were made, which 
met with the approbation of the tin men in London and 
Worcester.* Upon this success, preparations were made 
for setting up a manufactory, by the same persons who
