ON THE VARIATION OF GRAVITY IN SHIPS' CARGOES IN DIF- 

 FERENT LATITUDES. 



To the Editors of the Philosophical Magazine and Journal. 



Gentlemen, 



IN your valuable publication for April last (S. 3. vol. xxii. p. 326), 

 you kindly inserted an article of mine entitled " On the Effect of the 

 Variation of Gravity on Ships' Cargoes in different Latitudes." On 

 turning to my manuscript, I find the article there headed, " On the 

 Variation in the Weight of Ships' Cargoes in different Latitudes." 

 As weight and gravity are not exactly synonymous, perhaps this title 

 is less ambiguous than that which was printed ; but be that as it 

 may, a very cursory perusal of the article is quite sufficient to show 

 that its design was to exhibit the variation in iveight of cargoes in 

 different places through which a ship may be supposed to pass. The 

 table adverted to in your note showed the weight of the burden of dif- 

 ferent vessels in each degree of latitude, they having a given tonnage 

 in the latitude of London. Whatever may be the merits or demerits 

 of the little article, I wish there to be no mistake ; the article states 

 the circumstance that suggested it'. The table was constructed pur- 

 posely to show how the weight of a body varies, supposing it to be 

 carried through different latitudes ; without the table the communi- 

 cation was rather incomplete, but as no room could be found to 

 squeeze it in, it is useless to say more about it. 



Your Correspondent K. K., in the present (June) Number (vol. 

 xxii. p. 503), in adverting to my communication, says, " the author
