merous astronomical observations, fully verified with a transit instru- 

 ment, having a telescope of forty-three inches focal length. The 

 meridian, thus traced, does not meet with any high land or elevation 

 whatever in passing Mars Hill ; but, on the contrary, it passes the 

 base of that eminence considerably to the eastward, and at a depres- 

 sion no where less than twelve feet below the level of the base of the 

 monument, which was erected to mark the source of the river St. 

 Croix, by the commissioners appointed under the fifth article of the 

 treaty of 1794, to ascertain and mark the true St. Croix, &c. The 

 base of this monument is surrounded, unless at seasons of extreme 

 drought, by the water constituting the extreme source of that river. 



The profile of Col. Bouchette shows an elevation of the surface of 

 the ground upon the meridian line, as it passes Mars Hill, of five 

 hundred and sixty feet above the level of the monument at the source 

 of the St. Croix; whereas by the survey of Major Graham, the true 

 meridian from the monument passes the hill at an actual depression of 

 twelve feet below the level of the base of the monument. The direc- 

 tion of the true meridian, as shown upon the profile presented by 

 Major Graham, was derived from numerous astronomical observa- 

 tions made with the above mentioned transit instrument; and the 

 elevations exhibited upon it were derived from a line traced with two 

 spirit levels, the one following as a check upon the other, from the 

 level of mean tide at Calais, Me. to the monument at the source of 

 the St. Croix, and thence along the meridian line to its intersection 

 with the river St. John. 



2. From Sir Wm. Jardine, dated Jardine Hall, by Lockerbie, 

 Feb. 15, 1844, acknowledging the receipt of Transactions of 

 the Society, and stating that he had forwarded to the Society 

 certain numbers of his Annals of Natural History; transmit- 

 ting a prospectus of the Ray Club, and asking if it might not 

 hope for support from this country. 



The Ray Club was commenced by Sir William, and other friends, 

 to advance the facility with which works on Natural History, not 

 always accessible, may be procured. Names and addresses to be 

 forwarded to Dr. George Johnston, Berwick-upon-Tweed, who has 

 consented to act as Secretary until the feasibility of the project has 

 been ascertained, and a council appointed. 



Every subscriber of one guinea annually, payable in advance, to 

 be members of the club.
