This analysis requires some explanation. The printer usually charges for composition by the sheet, supposing the type to be all of one kind; and as this charge is regulated by the size of the letter, on which the quantity in a sheet depends, little dispute can arise after the price is agreed upon. If there are but few extracts, or other parts of the work, which require to be printed in smaller type; or if there are many notes, or several passages in Greek, or in other languages, requiring a different type, these are considered in the original contract, and a small additional price per sheet allowed. If there is a large portion of small type, it is better to have a specific additional charge for it per sheet. If any work with irregular lines and many figures, and what the printers call rules, occurs, it is called table work, and is charged at an advanced price per sheet. Examples of this are frequent in the present volume. If the page consists entirely of figures, as in mathematical tables, which require very careful correction, the charge for composition is usually doubled. A few years ago I printed a table of logarithms, on a large-sized page, which required great additional labour and care from the readers,(3*) in rendering the proofs correct, and for which, although new punches were not required, several new types were prepared, and for which stereotype plates were cast, costing about L2 per sheet. In this case L11 per sheet were charged, although ordinary composition, with the same sized letter, in demy octavo, could have been executed at thirty-eight shillings per sheet: but as the expense was ascertained before commencing the work, it gave rise to no difficulties.
