From the two laft Tables (fuppoling them to be accurate, and on the whole they appear to bethe mofl fo of any that have been ever given) the proportional quantity of acid and bafe in anyneutral fait may be found by a fimple calculation. In this ftate the fait is fuppofed to be abfo-lutely free from water of cryftallization, and at the utmoft degree of drynefs. Such a ftate how-ever only can exift with part of the above compounds, form any of them cannot be expofed to aheat fufficient to expel the water which they contain without at the fame time driving off or de-compoling a portion of the acid or the bafe. This is the cafe with all the ammoniacal falts, withmolt of the nitrats, with the alkaline carbonats, with muriat of magnelia, &e. fo that there ftillis wanting to complete the fubjedt a Table of the adtual compofition of thefe and other falts atdifferent degrees of drynefs. This however we have not thought it neceffary to add in this place,as we have already mentioned the compofition of molt of them under their refpedtive heads, andit mult be acknowledged that the confiderable difference which is found in the eftimations ofchemilts of eminence, fhews the neceffity of further refearches, and of a much greater accuracyregulating the temperature at which deficcation is made, than is coiqmonly obferved.
