ceptacles of the grub or maggot, after the eggs are 

 hatched. The insects which lay their eggs in the 

 skin of animals are provided with an instrument 

 called an ovipositor, with which they penetrate the 

 skin, and at the same instant they deposit their eggs. 

 The tumours produced by the grub after it is hatched 

 create considerable uneasiness to the sheep ; and when 

 a single sheep has several of these in his hide, he will

 by the motion of the grub. The shepherd, when he 

 sees this uneasiness manifested, should search for the 

 tumours, and pick out the grubs with a pin, or squeeze 

 them out with his thumb nails, as there is always a 

 small aperture on the surface of the tumour through 

 which the grub escapes in due season. 



The sheep-tick, called hippobosca ovina, is also very 

 troublesome to sheep and lambs, especially before they 

 are smeared. 



REMEDIES. When the former of these vermin in- 

 fest sheep, the flowers of sulphur mixed with hogs' 

 lard, and rubbed over the fleece, generally has the 

 effect of preventing insects from alighting on them 

 for the purpose of depositing their egg. A solution 

 of aloes, spirit of turpentine, and black soap have also 

 been successfully used for this purpose. Strong, 

 colourless spirit of tar or carbolic acid, has likewise the 

 effect of preventing flies from alighting on sheep. 

 It also destroys the tick. A solution of corrosive- 

 sublimate has the property of extirpating flies.
