Letter, from John William Lubbock to Sir John Herschel, dated at High Elms, Farnborough Autograph letter signed by sender. Has been looking at John Frederick William Herschel's treatise on meteorology, especially the part relating to the barometrical formula. It seems that John Frederick William Herschel missed John William Lubbock's paper on refraction published in Transactions of the Astronomical Society, and is therefore not aware of the true nature of P. S. Laplace's atmosphere; comments on this. 11 September 1861
