 • Tkkingthe most probable supposition, that nifrtyittiftkstyH6ife 

 stands in the same relation to metastyrole as nitrostyrole to 

 styrole, or nitrobenzide to benzole, that is, that one equivalent 

 of hydrogen in the carbo-hydrogen is replaced by one equiva- 

 lent of hyponitric acid, the formula for metastyrole will then 

 be C,4 H~, from which it is seen, that by the metamorphosis 

 of the body, Cjg Hg, the number of equivalents of carbon and 

 hydrogen in the new compound has diminished by one-eighth. 

 The formula of nitrometastyrole differs from that of an- 

 thranilic acid and protonitrobenzoene by containing one equi- 

 valent less of hydrogen. The formula of the two latter bodies 

 is Ci4 H7 NO4. Late investigations* have shown that proto- 

 nitrobenzoene, as well as anthranilic acid, when distilled with 

 lime, is decomposed into carbonic acid and aniline. As nitro- 

 metastyrole is a body completely analogous to nitrobenzoene, 

 we expected to form under similar circumstances a base with 

 the formula Cjg Hg N. The experiment did not however turn 

 out to our expectation. On distilling a mixture of lime and 

 nitrometastyrole, a very complicated reaction follows, a large 

 quantity of carbon is deposited, ammonia is evolved, and at
