Physical Amusements and Diverting Experiments: Composed and Performed in Different Capitals of Europe, and in London

The honour of performing several physical amusements before their Britannic Majesties and the Royal Family, was an event that flattered my ambition in the highest degree. To obtain their suffrages, and those of that part of this enlightened nation, before which I have repeated the same experiments and amusements at the Theatre Royal, Hay-Market, was the summit of my wishes. Having obtained these two desirable ends, I blessed the moments I had devoted to the study of natural philosophy and mathematics; to them I am indebted for these inestimable advantages.

Some invidious hints insinuated relative to the means I practised for performing these several experiments came to trouble the happiness I enjoyed. The opportunities I had of demonstrating publicly the simplicity and fairness of the execution of my experiments, which had appeared complicated to such a degree as to require a confederate, have put me in the happy way of destroying those unfavourable impressions, and of undeceiving those persons who honoured me with their presence; their repeated applauses have been a very flattering testimony of their approbation of my endeavours to amuse the public.

Several persons of the first rank having signified their wishes that I would publish some few easy means of amusing a company, whether in town or in the country; I could not refuse to comply with their desire: this is the motive of this little publication. Being near my departure for France, I shall trace hastily a few experiments, which will be as simple as they are entertaining, and easy to be performed. If amongst them there should be found, by chance, some that are known, or even printed, I hope it will not be taken amiss, nor I shall be looked upon as a plagiary. Unacquainted with this town, I cannot be informed of all that exists in print: besides, as in this age the study of natural philosophy is so universal, it cannot be in the least astonishing if some of the experiments resulting from that science were already known. Therefore I claim by anticipation the indulgence of those who read this work. My only wish is to be so happy as to unite in this book the clearness and precision necessary to enable my readers to perform what is contained in each chapter. My project on my return to this metropolis, is to endeavour to obtain again the suffrages of the nation, by performing some new experiments. To reveal on this occasion those which I have performed till now, would be hurtful to my fortune: besides, most of them require a great deal of mechanism and great preparations. Others depend on much dexterity and subtilty; which are out of my power to give, and out of a possibility to be communicated in writing.

If this feeble Essay, which I have the honour of presenting to the public, is favourably received, I promise on my return, and after I have merited their favour, to publish the means I have used to execute all I have performed.
