The oxide in the analysis of the adhesive slate by. B.u- v 



.cholz was part of iron, part of manganese: and in the 

 analysis by Klaproth the gas that escaped is included in the 

 •22 of water. He likewise found an alkali present, but in 

 too small quantity to be weighed.

ROF. STROMEYEIi has here given a systematic ar- Stromeyefs 

 rangement of the different substances, that are the parti- chemical 

 cular objects of chemical science, with a pretty copious 

 collection of synonimes in German, Latin, French, and 

 -English, The only innovation he has allowed himself, ac- 

 cording to his preface, is the classing of oil, sugar, starch, 

 gluten, and several other vegetable and animal matters, as 

 oxides with compound, radicals, consisting either of carbon 

 and hidrogen, or carbon, hidrogen, and nitrogen. Among 

 these he makes wax differ from fixed oil only in being more 

 oxided; and adipocere from fat in the same manner. By 

 the b)', the only name he gives for adipocera in the English 

 column is fat-wax, a literal translation of the German 

 fettzcachs.

 led to this by the observation of Proust, that muriatic acid 

 completely frees tin from arsenic : and on this occasion he 

 convinced himself by experiments, that the fetid hidrogen
