Any Alcali will reftore them into their former Co- 

 lour, as was {hewn me in feveral Experiments. 



Pifmires diftilled by themfelves, or with Water, 

 yield a Spirit like Spirit of Vinegar, or rather like the 

 Spirit of Viride Mris. 



Of this they have diftilled great Quantities, and 

 given it inwardly and outwardly in Confumptions, 

 with good Succefs. 



Lead put into the Spirit, or fair Water, together 

 with fhe Animals themfelves, being alive, makes a 

 good Saccharum Saturni. Iron put into the Spirit, 

 affords an aftringent Tin&ure, apd, by Repetition, a 

 Crocus Martis. 



Take Saccharum Saturni thus made, and diftill it, 

 and it will afford the fame acid Spirit again, which 

 the Saccharuyn Saturni made with Vinegar will not 

 do 5 but returns an inflammable Oil with Water, but 

 nothing that is acid. And Saccharum Saturni^ made 

 with Spirit of Viride Mris^ doth the fame in this re* 

 fpe£t with Spirit of Pifmires, which no other acid 

 Spirit made of Vegetables doth that he knows of. 



But, in this Particular, Spirit of Pifmires comes 

 nearer Vinegar and Spirit of Nitre, than Oil of Vi- 

 triol, Spirit of Salt, or the acid Spirit of Sal Armo- 

 niac, in that it makes an aftringent Tinfturc of Iron^ 

 and the others art aperient. 



When you put the Animals into Water, you muff 

 ftir them about to make them angry, and then they 

 will fpirt out their acid Juice. 



No Animal that ever they diftilled, except this, 

 yields an acid Spirit, but conrtantly urinous ^ namely, 

 an Oil and a faline Spirit : And they have diftilled 

 many, viz. as Flefh, Fifti and Infe&s. 



They defire you to enquire, whether any other Ani- 

 mal diftilled did ever yield any acid Spirit. 



They have made of Pifmires divers Salts, of which 

 you rpay hear more hereafter, if you defire it y but 

 at prelent they had not Leifure to ebnfult their Notes.
