Sandwich, stating that he saw several of them during the last week of 
January. As he did not give me ee day of the month, I cannot give it, 
but of my date, the 2d of February, I am positive, as I took a note of it

NATIONAL INSTITUTE OF SCIENCE, LETTERS AND ART. On the evening 
of Dec. 29, 1868, a large number of the members of the National Insti- 
tute, as well as those interested in the work, met in New York City to 
organize two of the Academies, 7. e., that of the Natural Sciences, and 
that of the Mathematical and Physical Sciences, into which the Institute 
is divided. We should mention that after several preliminary meetings, & 
Vnesi was drafted, and on May 29th a copy of it, with the follow- 
rcular, was sent to the leading scholars of the country : 
lack of any means of easy intercourse and free Communication, and conie 

etters, artists, and ‘scientific men in the United States. They constantly find them- 
of this lack by their weakness as a class, because although a class
