cording to the latter, the contrary is the case, and the extent is 

 only 0.05 of an inch. 



Lastly, the author endeavours to ascertain how far the barometer 

 is affected by the direction of the wind, and gives in the form of 

 tables the mean results of observations bearing upon this point. 

 The fluctuation, he observes, due to this, is much greater than that 

 due to any other cause. The barometer is lowest, as might be 

 expected, when the wind is in the rainy quarters of S.W. and 

 W.S.W. There are not yet sufficient data for any general conclu- 

 sions with regard to the influence of electrical phenomena on the 

 weather.

A paper was read, u On the Errors in the Course of Vessels oc- 

 casioned by local attraction, with some remarks on the recent 

 loss of His Majesty's ship Thetis." By Peter Barlow, Esq. F.R.S. , 

 &c. 



The author observes that the errors arising from the deviation of 

 the compass produced by the attraction of ships, were formerly 

 much less considerable than at present, from the comparatively 

 small quantity of iron existing in the vessel. The increase of this 

 disturbing force in a modern ship of war is easily accounted for by 

 che immense proportion of iron now employed in its construction,
