may tend to remove one of the many difficulties which they have to 

 encounter. 



Being under the impression that the instrument which I have 



proposed will obviate some of the difficulties in the measurements 



of dilitation and temperature, I may be excused for adding another 



to the long catalogue of those which have been heretofore described.

Art. IX. — Notice of a Scientific Expedition. Communicated by 

 Prof. E. Emmons, of Williams College. 



Since the appearance of the publication of Dr. C. T. Jackson and 

 of Mr. Alger, on the mineral riches and geological structure of Nova 

 Scotia, a strong desrie has been felt by us to visit the same interesting 

 region. Though the harvest had been principally reaped by those 

 gentlemen, yet the variety of the mineral productions, the instruc- 

 tive geological formations, the scenery, the wonderful tides, and 

 even the fogs of those shores, all conspired, together with other less 

 weighty considerations, to give the proposal of a visit to that region, 

 during our succeeding vacation, an unusual popularity. 



Accordingly arrangements were made in the latter part of the 

 summer term, by the young gentlemen of the Society of Natural 

 History,* and three instructors, to put in execution the proposed 

 project of an expedition to Nova Scotia, during the fall vacation. 



Circumstances obliged us to limit our absence to twenty days 

 from Boston : a period much too short to accomplish all we had 

 proposed to ourselves. 



In this place it is proper to remark, that the following account 

 must be brief for two reasons, viz. : 1st. the story of the voyage 

 has already appeared in several weekly publications. 2d. A for- 

 mer number of this Journal contains nearly a full description of the 

 mineral riches and geological formations of this province. 



The party left Boston for Lubec, in the sloop Flight, Captain 

 Hallett, on the afternoon of the 25th of August, and a fair wind 

 carried us to that port in about forty hours. 



Our object in visiting that place was to obtain a more favorable 

 clearance for the British Provinces. This we were enabled to do
