WITH THE MARINE ACID. 331 



cordingly, although the affinity of the nitrous 

 acid is weaker than that of the vitriolic, there is 

 nothing fo wonderful in the circumftancc juft 

 now related. We arc to confidcr the propcn- 

 fity of mercury towards the vitriolic acid, as o- 

 pcrating to incrcafc the influence of the nitrous, 

 and from hence it proceeds that we obtain 

 a vitriolatcd mercury but little foluble in 

 wi.ter, and, on account of the fmall quanti- 

 ty of the menflruum, falling to the bottom of 

 the vcflcl in the furm of cryilals ; while, on 

 the other hand, the nitrous acid uniting 

 with the Jixivial fait produces a perfect nitre. 

 Further, if this vitriolated mercury is 

 mixed with common fait, and fubmittcd to the 

 fire, a new exchange of parts takes place: for 

 the mercury combining \\itli the muriatic fait 

 is fublimed under the form of corrofivc mercu- 

 ry, the matter remaining at the bottom of the 

 vcilel being a Glauber's fait, generated by the 

 acccfllon of the vitriolic acid to the mineral al- 

 kali. 



The rcfiilt is nearly the fame, if you employ 

 nitrated mercury, common fait, and vitriol. The 

 ufc of this preparation is preferred by Bcgui-
