190 Miscellanies. 



One thousand eight hundred grains of bismuth, finely powdered 

 and mixed with six hundred grains of sulphur, which had been sub- 

 limed, were fused with the same precautions as before, and kept in 

 fusion for about half an hour. The resulting sulphuret weighed 

 2003.6 grains =1800+203.6, or the composition is

of one per cent, only in excess, to form a di-sulphuret, considering 

 the atomic numbers 72 and 16 the true ones. The bismulh employ- 

 ed was the common bismuth of commerce, which contains, according 

 to Thomson, about one third of one per cent, of iron, so that by the 

 sulphur also combining with the iron, the combined sulphur in both 

 together should be a little in excess.

19. Address of Mr. H. R. Schoolcraft, at Detroit, on the condi- 

 tion of the North American Indians, May,. 1832. — Lecture on To- 

 bacco, by Prof. Elizur Wright, of the college at Hudson, Ohio, 

 May, 1832. 



Address before the Temperance Society of the Medical Class, in 

 Dartmouth College, Oct. 1832, by Prof. Oliver. — Temperance Re- 

 corder of Albany. 



If these subjects are trite, they have lost none of their importance 

 by iteration. We are glad to see that men of talents and station 

 are willing to come before the public, and enter their solemn protest 

 against strong drink and its ally, tobacco. Mr. Schoolcraft has hap- 

 pily, although painfully sketched the destroying effects of alcohol 

 upon the aborigines ; Mr. Wright has forcibly and very plainly ex- 

 hibited the evils and offensiveness of tobacco, and Prof. Oliver has, 

 with the skill of an able professional man, sustained one of the 

 greatest causes that has ever been brought forward in the world.
