PRINTED FOR ARCHIBALD CONSTABLE & CO. EDINBURGH; འའ་་་་་、 1819. ΤΟ SIR GEORGE STEWART MACKENZIE, OF COUL, BART. F. R. S. PRESIDENT OF THE PHYSICAL CLASS OF THE ROYAL SOCIETY OF EDINBURGH, AND VICE PRESIDENT OF THE SOCIETY OF SCOTTISH ANTIQUARIES. &c. &c. &c. As you were the first person who saw the Kaleidoscope, and predicted its popularity, I am naturally led to lay the following description of it before the public, under the sanction of your name. I might have been more flattered with the interest which you took in the success of this instrument, and with the assistance I have so often received from you in other researches, had I been less acquainted with the zeal and ardour with which you have devoted yourself to the promotion of every object of science, and of public utility. |
