Philips' Model of Halley's Comet, Earth and Sun. Designed by

E. Rupert Hicks, F.R.A.S. (G. Philip and Son. ls. net.)—Here we have a chart in which the sun and the paths of the comet and earth are given on a scale of about twenty million miles to the inch. At the end of one pointer is the earth, at the end of another the comet, the latter with an appendage which represents the tail. The two paths are marked with months and days, so that by moving the two pointers to the place of any given day we can see the relative positions of the two bodies. The comet will be nearest to the earth on May 19th, when it will probably envelop us with its tail. Very soon after this date it should be visible in the Western sky, " a splendid object," says Mr. Hicks ; but no one, we imagine, can be sure that it has not wasted since its last visit to the solar system.
