A similar result will be obtained by using all the other numbers, including 8 (72); but the 8 must in all cases be omitted in the multiplicand.
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.
NOAH’S ARK AND THE GREAT EASTERN STEAMSHIP.
The following comparison between the size of Noah’s Ark and the Leviathan (Great Eastern), both being considered in point of tonnage, after the old law for calculating the tonnage, exhibits a remarkable similarity. The sacred cubit, as stated by Sir Isaac Newton, is 20·625 English inches; by Bishop Wilkins at 21·88 inches. According to these authorities, the dimensions will be as follows:—
