Botryitis^^ is sometimes black and sometimes purple-red,^ 

 and resembles a bunch of grapes^^ in form, when making its 

 first appearance. Zoroaster says, that bostrychitis^* is a stone 

 which is more like the hair of females than anything else. 

 Bucardia^^ resembles an ox-heart in appearance, and is only 

 found at Babylon. Brontea^^ is a stone like the head of a 

 tortoise, which falls with thunder, it is supposed : if too, we 

 are to believe what is said, it has the property of quenching 

 the fire in objects that have been struck by lightning. Bolos" 

 is the name of a stone found in Iberia,^® similar to a clod of 

 earth in appearance.

Cadmitis differs only from the stone that is known as

 •wliicb is known as Botryolite. 



6* "Hair-stone." This was probably either Iron alum, known also as 

 i\lun de plume ; Alunogen, known also as Feather Alum or hair salt; or 

 Amianthus, also called satin Asbestus. See B. xxxvi. c 31.

^^ "Thunder-stone. 



" *' Clod-stone." It may possibly have been a kind of Geodes. See

 toad, but in reality the fossil tooth of a fish.
