TO HIS ROYAL HIGHNESS

THE PRINCE ALBERT, K.G.

SIR,

The honour of being allowed to dedicate this volume to your Royal Highness, must be attributed rather to the earnest desire of your Royal Highness to promote the arts and sciences, than to the merits of the work itself. As I have endeavoured to aid the manufactures of Great Britain, by giving these discoveries to the public, I trust this book will receive your Royal Highness' gracious approbation.

I remain,

With the greatest respect,

SIR,

Your Royal Highness most dutiful

and most obedient Servant,

ALFRED SMEE.
