had to the fierceness of the spirits, transmitted to the crooked teeth, to be 

 revenged of those against whom these beasts are provoked ; which angry 

 spirits, being thrust into the flesh and veins, infect the spirits and blood of those 

 that are bitten. To which our author answers, that it is hard to maintain, 

 that the vindicative spirits can pass through a body so solid, as teeth are, espe- 

 cially since the little teeth have been found by experience to cause as dangerous 

 effects as the great ones, after these had been broken out ; and that therefore it 

 may be justly doubted, whether by the said bread crumbs all the salival liquor 

 about the teeth of an animal alive could be taken away, as it may be truly af- 

 firmed, that the viper's teeth are incessantly plunged into their sheaths, and do 

 there continually fill themselves with the said juice. 



But he considers withal, that in hot countries this liquor may work alone, 

 when conveyed into our flesh by the teeth of a dead viper, or even with an ear 

 picker, into a wound; as it comes to pass in Italy and in hot countries; but in 

 France and in colder parts, especially such vipers being used as are kept in tuns 

 and brought from afar off, the said juice not being strong enough alone, needs 

 to be made keen by the bilious breath of the angred viper.*

This description contains several things that may increase the materials for a 

 history of nature. This author delivers what he has met with in the country 

 above-mentioned, in four sections. In the first he discourses of the earths there 

 found: as marls, clays, fullers earth, tripoli, black chalk, a vermilion earth, 

 melting like butter on the tongue, and oker. In the second, of concrete juices, 

 as salt, nitre, alum, vitriol, sulphur, bitumen, &c. In the third, of stones, 

 especially spars, touch-stones, marble, the lapis specularis, blood-stone, schistus, 

 lapis samioides, crystal, brontia and ceraunia, (vulgarly called thunder-stones) 

 several sorts of belemnites, some of which being rubbed smell like burnt horn ; 

 eagle-stones, cornu ammonis, &c. In the fourth, of some uncommon springs.

We mention this book only to give notice, that it is now printed by itself in 

 England; referring the reader for the account of the contents thereof to N° 73, 

 where it was spoken of, when we saw it printed in Holland, together with the 

 author's book De Mot it Cordis et Sanguinis. 



♦ It is amusing enough to see that this writer should not be able to divest himself of the idea of 

 •' the bilious breatli of tlie angred vipers," while he admits the existence of the yellow liquor at the- 

 roots of tlie teeth.
