Palladium affert- Van JVIons writes me word that at Paris they Tay that it is 



of the ncwmetal^'^*- P^^^'^^^i* ^^^ ^^^is new metal, which with mercury compofes 



with iperwiy. palladium; but that has very little to fay to the purpofe, for the 



lingular thing in palladium is, nof what regards platina, but 



jwr'hat regards mercury, and the fufibility of the combination. 



,J3efides there muft have been platina in my palladium, as I

M»nufaaure of Lanlpadlus tells me that he has made feveral hundred weight 



Um^Xs^^ of fugar from the red beet ; but the manufadory he eftablifhed 



has failed. It coil him within two gros per lb. as much as the 



common fugar of equal quality, but then he had a refiduum fit 



Tor fermentation, which was clear profit. 



Aguftlte IS i had made fpme progrefs in the analyijs of the Saxon beryl, 



inerely phof. when I received a letter fron> Berthollet, in which he told me 



^ * that Vauquelin had found the aguftite to be nothing more than 



phofphate of lime. I continued my experiments however, 



and obtained the following refults. Having boiled muriatic 



acid upon the pi^lveri^ed mafs which contains the Saxon beryl. 



Muriatic folu- 1 obtained a folution of the pretended agurtjte. I precipitated 



tioaof Saxon ^^y ammonia, and, upon examining the precipitate, found it 



amm. gave phof."' ^o be phofpbate of lime. To have no doubt as to the phofpho- 



of lime. This .rJQ. acid, I treated 1500 grains of this prepipitate with half 



by fulph. acirt^ ^*'-^ weight of fulphuric acid, walhed the mafs, and evaporated 



and the purified to drynefs. I re-diflolved as much as was foluble in diftilled 



reduced w ac • '^^^^^^» ^"^ faturated the liquor by ammonia. By evaporating 



t«al phoiphorus. once more, I obtained phofphate of ammonia, which I de- 



compofed at a ilrong red heat, and obtained phpfphofic acid, 



which gave no trace of fulphuric or any other acid, or of any 



dearth, alkali, or metal. I mixed this with pounded charcoal, 



and by diftillation in a ftrong fire obtained a confiderable quan^ 



' tity of phofphorus. Thus then the fimple earth of Mons- 



I'rDfnfdorf is^ phofphate' of lime.
