que aquas ex ore profluit, ut ftatim melius habeant pecora et 

 prorfus convalefcant. Alii pro remedio in pharmacopoliis emunt 

 radicem tormentillse ; plerique tamen et pene omnes offibus ac- 

 quiefcunt. Videtur (quia ruftici rationem nullam dare fciunt) 

 quod pecora plerumque primo vere, terra adhue humoribus nimiis

 Unicuique tamen fuum relinque judicium." That according to 

 this learned gentleman's opinion, the bones of the cows are mol- 

 lified by nothing but the extreme moifture of this grafs, is what 

 I mull join with Simon Paulli in doubting ; yet, I cannot poffi- 

 tively afTent to the opinion of the latter, that the foil where this 

 plant grows muft contain either quickfilver or lead ore, and that 

 it is the mercurial fpirit infinuated into this. plant, which thus 

 corrodes and difiblves the bones. But others may form a better 

 judgment of the matter than I can. - 



Among this clafs of noxious roots in Norway, muft be ranked 

 Iglegrafs \ the peafants in many places are very apprehenfive of the 

 mifchiefs of this plant, efpecially in the government of Nord- 

 fiord, where they fpare no pains to clear their meadows of it, as 

 it operates on the fheep and goats by a violent fpafmus or con-

 fhooting up a kind of bufh of thick items, or twigs ; the leaves 

 narrow, oblong, and indented, with blue flowers at the end of 

 the ftems, which about harveft produce a hollow bud of twice

 found full of worms and other infects. It grows chiefly in a cold,

 that it has fome affinity with the Anemone; likewife, according 

 to Lonicer's defcription of it, with the Sideritis or ironwort, ex- 

 cept that inftead of white or yellowifh flowers, it has blue. The 

 eating of this plant in fheep and goats, and fometimes, tho' fel- 

 dom, in cows, is followed by the Virdfygee, a kind of vertigo, the 

 fymptom of which is fucha contraction of the nerves, towards 

 one fide, that the neck and head are violently distorted towards 

 its hind-parts, under which diftortion the beaft continues turning 

 round till it falls, and foon after dies. Sometimes, though not 

 often, a fheep is faved by opening a vein in the neck, whereby
