Copy of letter, from Sir John Herschel to Adam Sedgwick, dated at Collingwood Copy of letter, copied as part of the correspondence project led by Colonel John Herschel FRS following the death of his father. [Robert Chambers's] Vestiges of Creation is shallow and full of errors. Tells Adam Sedgwick not to spare it when he reviews it. Discusses various topics including the nebular hypothesis, P. S. Laplace, central heat in gravitation, and the density of planets. Also, the 'nonsensical calculations' of Auguste Comte's astronomy. 15 April 1845
