mixed with oil of mastic is used to anoint the eye and 

 purges away the malady. Running at the eyes is 

 stopped by pearl-barley sprinkled with honey-water 

 and applied to the eyebrows and cheeks ; wild parsnip 

 seeds and the juice of the horse-radish diluted with 

 smooth honey assuage pain in the eyes. But when- 9 

 ever honey or any other juice is introduced into the 

 remedies employed, the eye will have to be anointed 

 all round with liquid pitch and oil to prevent its being 

 infested with flies ; for not only flies but also bees are 

 a^^tracted to the sweetness and odour of honey and 

 other medicaments. 



XVIII. Much harm too is often caused by a leech Ben>edie« 

 swallowed with the drinking-water, which, fastening which hare 

 on the throat, sucks the blood and blocks the passage f^c^es!^*^ 

 of food with its own added bulk. If the leech 



is in such a difficult place that it cannot be re- 

 moved by hand, you should insert a pipe or reed and 

 then pour in warm oil ; for if this touches it, the leech 

 immediately falls off. The odour from a burnt bug 2 

 may also be introduced through a pipe (for when a 

 bug is put upon the fire and has produced smoke, 

 the vapour given off reaches the leech through a 

 pipe) and this vapour dislodges the leech from 

 its clinging hold. If, however, it is attached to the 

 stomach or intestine, it can be killed by pouring hot 

 vinegar through a horn. Though I have prescribed 

 these remedies to be used for oxen, most of them are 

 certainly suitable also for all the larger kinds of 

 cattle. 



XIX. It is necessary also to construct a machine How to

in which one can enclose beasts oi burden and oxen machine for
