 According to the author the phenomenon of tides is wholly unconnected with the attraction of the moon, and caused 

 solely by the heat of the sun, which he supposes to produce * periodical swellings ' of the ocean, followed by ' reactions '. 

 The above pamphlet was not budgetted by Prof, de Morgan.

 'Notice sur I'heliographie, par .1. X. Niepce ' (co-inrc»<o/- with the aitfTior), 'Modifications apportoes au procede de 

 M. Niepce par M. Uaguerre', 'Notice historique sur lo procede du Daguerreotype ', etc. etc., and the account of his 

 discovery of the Diorama— the delight of many boys fifty years ago. 



'The discovery of the Daguerreotype was announced in Jan. 1839, but the details of the process were not made public 

 till August of the same year. It consists of exposing a metal ]»late covered with iodide of silver for a suitable time in 

 a photographic camera, the plate being after wards transferred to a dark room, and exposed to the vapour of mercury, which 

 develops tlie latent iuiage, it being afterwards fixed. Although this process has become almost obsolete, it was really 

 the first which was of any practical value, and experts all agree that no other known process renders some subjects— «.</. 

 the human face — with such fidelity and beauty.' — T. C. Hepworth.
