The author was a member of the well-known family of distillers at South Lambeth, and was the first Englishman to 

 ascend Mont Blanc, six days later than Saussure. 



This was the only volume printed at the author's private press, out of three proposed to be issued. The work was never 

 published, but presented only to some public institutions and individuals interested in naval architecture. ' His 

 magnetic observations were superior in accuracy and extent to any earlier work of the kind. They served to determine 

 more precisely the laws of the diurnal variation, as well as to fix the epoch and amount of maximum Westerly declination 

 in England . . . The data accumulated by Beaufoy enabled Lament in 1851 to confirm his discovery of a decennial period 

 in the amount of diurnal variation, by placing a maximum in 1817.' D. N. B.
