It will be observed that this list only contains lecturers who had 

 not previously 9,ppeared before the Institute. The whole programme 

 was carried out with no change or failure, and at an expense not 

 exceeding one-half of that incurred for the preceding course. The 

 audiences, at these lectures, consisted mainly of members of the 

 Institute, and their families ; and as the attendance was uniformly 

 large, it may be regarded as fortunate that this means has been 

 devised for drawing together, at least for a few nights of each year, 

 those who evince a fondness for scientific investigations. 



Tlie twenty-ninth annual report of the American Institute to the 

 Legislature of the State, which has been in the process of printing 

 since the close of the exhibition, is just completed, and will be 

 delivered to members within a few days. It is the largest, and, with- 

 out doubt, the most varied and valuable volume of Transactions ever 

 issued by this institution.
