were blue. They were thrown into a mould after be?ng 

 moidened, and produced a loaf of pretty white fugar, weigh- 

 ing four pounds, and in tafte peffeclly fimilar to that of com- 

 mon fugar. 



In February, Profeflbr Lampadlus made a fecond trial : 

 the juice in this cafe was riot altogether fo white as the 

 former, and he obtained from it only three pounds and a 

 half of fugar. From the different remains and fvrups which 

 he procured by filtration, he obtained each time feven pounds 

 of a kind of rum of very ftrorig fpfrit. Encouraged by this 

 fuccefs, Profelfor Lafnpadius and a rich citizen of Freyberg 

 named Kanitzki, have eftabliflied a large manufaftory of 

 this kind of fugar. The fird refults of their undertaking 

 have been already publiflicd.

 ftitrous gas. 



ijdlv, Ti will not explode with oxvgen by the elc6lric 

 fhock in a clofe veird. 



3dly, It burns like' hydrc-earbons^:, but with a bluiih- 

 green flame. And, 



4thly, It is permanent over water. (S^ftroh XII.)' 



* It muft be firft noticed, that it is never pure when obtained from the 

 nitrous etherifed gas ; nor am 1 aware how it is to be purihtd, unlefs the 

 nitrous gas could, be taken from it without being converted into nitrous 

 acid; for, by that acid> it would p-obabiy be itfelf converted into nitrous
