ORIOINAL EDITION- of Kepler's second great work ('his chief work' IF. W. R. Loll), containing for the first time his 

 'third law' : The square of a planet's periodic time is proportional to the cube of its mean distance from the sun. As 

 is well known, these three laws formed the ground-work of Newton's discoveries, and are the starting point of modern 

 astronomy.

'In his Stereometria he determined the volumes of certain vessels and the areas of certain surfaces, by means of 

 infinitesimals instead of by the long and tedious method of exhaustions. This use of infinitesimals was objected to by 

 Gulrlinus and others as inaccurate, but though Kepler's methods are not altogether free from objection, he was substan- 

 tially correct, and by applying the law of continuity to infinitesimals he prepared the way for Cavalieri's method of 

 indivisibles [v. No. 735, ante], and the infinitesimal calculus of Newton and Leibniz.' IF. IF. R. Ball.

' A few years after the close of the XVI. Century another splendid new star burst forth in the constellation of Ser- 

 pentarius. The phenomenon was witnessed by Kepler, who wrote an interesting dissertation on the subject of its 

 appearance. It was first seen on 17 October, 1(504. It surpassed in brightness the stars of the first magnitude, as well as 

 the planets Mars, Saturn, and Jupiter ... It began to decline soon after its appearance, and finally ceased to be visible 

 between Oct., 1605, and Feb., 16CO.' Prof. R. Grant.

' The value of these tables appears from the fact that they ranked for a century as the best aid to astronomy. Appended 

 are tables of logarithms and of refraction, together with Tycho's catalogue of 777 stars, enlarged by Kepler to 1005.'
