more than one half of this water, it ftill retained the fame 
black quality, and ilruck as deep with galls as ever, and at 
lafl: it yielded him a real and genuine vitriol. The oker which 
this water let fall in very great plenty, he did not much mind, 
being a thing common to all ink-like waters. The Dofl:or was 
furprifed at this pha^nomenon, and could not bring himfelf to 
think it poffible, rhat the pyrites lying conftantly under water, 
/liculd ever yield vitriol, and he knew of nothing elfe, at leaft 
in England^ that it could be obtained from. But having an 
opportunity to vifit this notable well, he found cut that this 
vitriol water, was what run thro* a drift made for the draining 
of a row of old wrought coal-pits a little above, and was 
informed by fome old men, that formerly wrought in thefe 
pits, that there was plenty of the pyrites there, by them called 
brafs-lumps; and that this drift was fbmetimes dry, and fome- 
times run with a plentiful ftream; which is as probable an 
account how this water comes to have vitriol in it, as any one 
may expc(fi. 
The Gall-Bee 5 hy Mr. Benj. Allen. Phil. Tranf. N° 245. 
P- 375- 
IN fome Aleppo galls, which the infers had not eat their 
way thro', Mr. Allen found a fort of bee, refemblmg our 
fmall lort of wild bees, they have long wings, a deep belly, 
and on the back, near the commiffure, to the body, it is of a 
j[^reenifh black, the reft reddiOi, near a cinnamon colour: 
Thefe galls are very gummy, and fome of them had a ftem, 
and the cavity round them was fo extremely gummy, that not 
the leafl: entrance to it appeared, tho' the bee was beginning to 
make its way out 5 and from this it may appear, that the armo- 
fpherical air is not neceffiry to the effence of life, before the 
organs of the body are employed ; but that it is maintained by 
a fubtilcr air, that pervades the more minute pores, as it is 
conveyed to fidi thro' the water: Mr. Allen alfo found in the 
greyer fort of galls, that are not fo rich in gum, a fmall 
ichneumon of a bright green.
