hlmfelf found out, or heard of any other animal^ that by di- 
ftillation or other wife yields an Acid fpirit. For my part , I • 
know of none ^ but if any do, they are probably th^favificouf 
Qud gregarious kind^ and generally fuch as are furnifti'd with 
ftings 5 of which weapon Pifmires are not unprovided^ Id* 
deed it (eems ftrange, that Nature (hould prepare and fcpa- 
rate in the Body of this Infeft without any fenfible heat , and 
that in good quantity, confidering the bulk of ih^ammaly a 
liquor the fame fcr kind with thofe Acid Spirits, which are by 
Art extraited out of fbme Minerals not without great force 
of Fire. 
''^^'^oubt not but this liquor may be of fingular ufe in Medi- 
eine. Mr, Fijher hzih afliired me, that himfelf hath made triaL 
thereof in fome difeafes with very good fucceft* 
Tofifcriph 
WHereas in the former account there is a paflagc liable 
to exception and miftake, vii{. Spirit of Salt and Oyl of 
SnlphHry dropd upon Cichory- flowers ^did not caufe them to chan^t. 
colour 5 for the clearing thereof you may pleafe to take notice, 
that it is to be underftood of the flowers entire and unbruifcd: 
For any Blew flowers being a little bruifed, and then a drop 
of Spirit of Salt or any other Acid Spirit let falfthereon, will 
turn inftantly red* The reafon is obvious 5 for that the leaves 
of the Flowers fas all the other parts of theplant ) being in* 
vefted with a skin or Membrane, the liquor dropp'd thereon 
cannot eafily penetrate it, and fo commix it felf with the in-? 
teriour juyce or pulp* Hence it is^that if thefe flowers be put 
into cold Vinegar, efpecially if the weather be cool, they will 
not change colour for a coDfiderabletime, but ifyou heat the 
Vinegar, they will change immediately. 
Whether the Ants do only drop this Tinging liquor upon 
the furface of the flowers , or thrufting their ftings into the 
body of the flower^do by them coiivey it immediately into the 
interior included Juyce, we cannot yet determine,but refer to 
future obfervation^ when the time of the year will afford us 
flowers.
