Abstract
IN NATURE, vol. xxi. p. 111, we described the ingenious planetarium recently invented by Signer Perini, and which has cost him seven years' constant labour. To-day we are able to present an illustration of this invention, which may give those of our readers who have not seen the original, some idea of its construction. The visitors are supposed to be standing underneath the dome, from which are suspended the sun and planets. Or course it has been necessary for purposes of illustration to greatly exaggerate the proportionate sizes of the planets, but our readers will see that for purposes of instruction Signer Perini's invention must be ol the greatest possible utility. or details we must refer the readers to our previous article on the planetarium, which we believe is still standing and may be seen at 77, Newman Street, Oxford Street.
