Waves. That they live upon some Food is manifest by the 

 little Shell-fishes which are found within them. And some 

 say, that about Torone they take Food after they have been 

 plucked from the Rocks ; and that from the Roots which 

 are left behind, they grow again. Also, upon those Rocks 

 (from whence they are pulled), there is to be seen some 

 Appearance of Blood sticking ; and especially in those of 

 Africa, which breed among the Syrtes. The Manse become 

 very large, and also the softest, about Lycia. But they are 

 more soft when they grow in the very deep Water, out of the 

 Influence of Wind. They are rough in the Hellespont; and 

 dense about (the Cape) Malea. In Places exposed to the 

 Sun they will putrify ; and therefore the best are in deep 

 Gullies. They are of the same blackish Colour when they 

 live, as when full of Moisture. They adhere to Rocks nei- 

 ther by any one Part, nor yet all over ; for there are dispersed 

 certain hollow Pipes, four or five commonly, by which they 

 are supposed to receive their Food. There are more (of these 

 Pipes), but above they are grown together. A certain thin 

 Skin may be perceived to be at their Roots. It is known 

 that they live long. The worst Kind of them all are those 

 called Aplysiae, because they cannot be made clean ; in them 

 the Pipes are large ; and they are throughout thick and 

 massy. 



CHAPTER XLVI. 

 Of the Caniculus marinus. 1 



THE Divers are annoyed very much with a great Number 

 of Caniculi marini that come about them, and put them in 

 great Danger. And they say, that these Fishes have a cer- 

 tain Cloud growing thick over their Heads, like that of the 

 flat Fishes, which presseth them, and hindereth them from 

 retiring backward ; on which Account the Divers have with 

 them sharp-pointed Weapons fastened to long Poles ; for 

 unless they be pricked with them, they will not turn away :

 sharks, Scymnium. Wern. Club.
