The phenomena and numerical relations to which I have re- 
rerred in this paper seem of considerable importance in their 
bearing upon the position of our sun in its cluster, the form of

iron reduced, and was removed by filtration. e liquid was 
now boiled, and as it remained clear, even after long heating; 
the absence of titanium might have been reg: demon-
