Horrocks's short life is one of the most shining illustrations in the whole romance of science. He observed for the first 

 time, with a little half-crown telescope, on a Sunday afternoon, Nov. 24 (O. S.), 1639, a Transit of Venus, having first finished 

 his Evensong, 'ad niajora avocatus qua?, ob huec parerga [astronomica] negligi non decuit.' He died next year, It40, in his 

 23rd year. 



' In the lunar theory he effected an improvement which would alone suffice to obtain for him an imperishable reputation. 

 His beautiful explanation of the inequality in the moon's longitude, termed the evection, by means of a libratory motion 

 of the apsides and a variable eccentricity, was the last great step made in the development of the laws of planetary 

 movement previous to the establishment of the theory of gravitation by Newton.' Irof. R. Grant.
