5. Mi ational se eel y of Science.—At a session held at Columbia 
College, N. Y., Oct. 23-25, 1877, the following papers were read :

tem =) On the inclinations in a direction retrograde of ‘the shadow of the 
pl 3.) On the luminous band which see encircle the m 
partial solar eclipse.—(4.) Whence came the inner satellite of Mars?
