other black resinous gall. Again it has another 

 growth, like a mulberry in shape, but hard and 

 difficult to break ; this however is not common. It 

 has also another growth like the penis in shape, 

 which, when it is further developed, makes a hard 

 prominence and has a hole through it. This to a 

 certain extent resembles also a bull's head, but, when 

 split open, it contains inside a thing shaped like the 

 stone of an olive. 1 The oak also produces what some 

 call the 'ball ' ; this is a soft woolly spherical object 

 enclosing a small stone which is harder, 2 and men 

 use it for their lamps ; for it burns well, as does the 

 black gall. The oak also produces another hairy 

 ball, which is generally useless, but in the spring 

 season it is covered with a juice which is like honey 

 both to touch and taste. 



3 Further the oak produces right inside the axil 4 

 of the branches another ball with no stalk or else 5 

 a hollow one ; this is peculiar and of various colours : 

 for the knobs which arise on it are whitish or black 

 and spotted, 6 while the part between these is brilliant

 rotten. 7 It also occasionally produces a small stone 

 which more or less resembles pumice-stone ; also, less 

 commonly, there is a leaf-like ball, which is oblong
