The vessel's position when the above were taken, was about 1^ miles S. W. 

 of Mud Point, they were all either taken, or their accuracy ascertained by myself. 

 Some latitude must however be given for the direction of the wind which I found 

 difficult to obtain, except when it was right ahead. I do not think the error would 

 amount to more than one or two points. 



The projection of the above register would seem to shew that the Aneroid will 

 bear a very fair comparison with the Sympiesometer in these gales, both in its 

 range and sensitiveness it was when first received regulated by the standard Baro- 

 meter at the Surveyor General's Office. The Sympiesometer, you may observe, is a 

 very high one.
