constituent to make the dip effective for the cure of Sheep-scab at 

 the strength approved. It is therefore inadvisable to make up the 

 dip bath by mixing two or more dips containing different ingre- 

 dients, even in cases where each dip has been approved for use 

 by itself. For exemple, to mix carbolic and arsenic dips may result 

 in destroying the efficacy of both ingredients, and even the mixing 

 of dips containing the same ingredients may result in the bath 

 being below standard. In some cases, also, the use of mixed dips 

 may injure the sheep. " 



Prescriptions for Sheep-Dips. The Journal of the Board of 

 Agriculture. June 1910, vol. XVII, n. 3, p. 238. 



" The following prescriptions for Sheep-Dips have been approved 

 by the Board of Agriculture and Fisheries for Sheep Scab, and can 

 be used by sheep owners who prefer to make up their own dips. 



1) Lime and Sulphur. Mix 25 Ib of flowers of sulphur with 

 12 l / 9 Ib of good quicklime. Pound or rub the mixture with water 

 until a smooth cream without lumps is obtained. Transfer this to 

 a boiler capable of boiling 20 gallons ; add to the mixture sufficient 

 water to make up 20 gallons ; boil and stir for half an hour. The 

 liquid should then be of a dark red colour ; if yellowish, continue 

 the boiling until the dark red colour is obtained, keeping the 

 amount of liquid up to 20 gallons by adding water if necessary. 



Half the above quantities may be used to make 10 gallons, if 

 more convenient. 



After the liquid has cooled, pour it off from any small quantity 

 of insoluble sediment. 



To 20 gallons of the mixture add 80 gallons of water to make 

 a bath. 



The mixture will keep good for twenty-four hours if kept in a 

 covered vessel, and for a month or even more if kept in jars or 

 drums securely corked. 



Period of immersion for sheep in this dip, not less than half 

 a minute. 



2) Carbolic acid and soft soap. -- Dissolve 5 Ib of good soft 

 soap, with gentle warming, in 3 quarts of liquid carbolic acid (con- 

 taining not less than 97 per cent of real tar acid). Mix the liquid 

 with enough water to make 100 gallons for the bath. 



This mixture after being prepared will keep good for three 

 months if kept in securely stoppered jars or drums in a cool place.
