WORKSHOP RECEIPTS was compiled to effect three purposes; to serve as a note-book for the small manufacturer; to supply the intelligent workman with information required to conduct a process, foreign perhaps to his habitual labour, but which it is necessary to practise at the time; and impart to the scientific amateur a knowledge of many processes in the arts, trades, and manufactures, which will, it is hoped, render his pursuits the more instructive and remunerating,

The novice would do well to remember that it is the individual skill of the workman in performing many apparently simple operations which renders those operations successful, and that

this skill is only obtained from long practice or natural ability. is A. pre-eminently superior manipulator resembles a poet in that

he is born, not made;' when therefore a receipt is tried for o the first time and is not thoroughly successful, the experi

mentalist should consider how far his own inexperience has contributed to the failure ere he condemns the receipt.
