CHANGES OF THE KALEIDOSCOPE.
The following curious calculation has been made of the number of changes which this wonderful instrument will admit:—
Supposing the instrument to contain twenty small pieces of glass, &c., and that you make ten changes in each minute, it will take the inconceivable space of 462,880,899,576 years and 360 days to go through the immense variety of changes it is capable of producing,—amounting (according to our frail idea of the nature of things) to an eternity, Or, if you take only twelve small pieces, and make ten changes in each minute, it will then take 33,264 days, or 91 years and 49 days, to exhaust its variations. However exaggerated this statement may appear to some, it is actually the case.
