Sheep Scab. 



[FEB., 



9. In pursuance of the recommendation contained in paragraph 

 34 of the Departmental Committee's Report the Board have 

 incorporated in the Order a Schedule* in which is set out the 

 composition of certain preparations which have been proved by 

 experiment to be suitable for use as sheep dips without detri- 

 ment to the fleeces of the animals dipped, and, if properly 

 employed, to be effective cures for Sheep Scab The Order pro- 

 vides that any one of these preparations shall constitute an effi- 

 cient sheep dip within the meaning of the Order, and an Inspector 

 will be justified in certifying that, where one of these preparations 

 is used, the prescribed dipping has been thoroughly performed 

 if each sheep has undergone a period of immersion of not less 

 than half a minute. Although the Board have not included in 

 the above-mentioned schedule any preparation containing arsenic 

 it is not to be assumed from this omission that the Board do. 

 not concur in the view expressed in the Report of the Com- 

 mittee (page 12) that "the arsenic dips are thoroughly effective 

 in curing Scab." The possible danger to human beings 

 attendant upon the preparation of such dips renders it advisable, 

 however, that they should be compounded by qualified persons 

 only. The Board at the same time recognise that there are a 

 large number of sheep dips on sale which may be regarded as 

 equally efficient cures for Sheep Scab, and they are making 

 arrangements for the examination of any dips for Sheep Scab 



* The Schedule is as follows : — 



Prescriptions for Sheep-Dips approved by the Board for Sheep Scab. 

 (Quantities for 100 gallons of bath.) 

 1. Lime and Sulphur. 

 Mix 25 lb. of flowers of sulphur with \i\ lb. of good quick-lime. Triturate the 

 mixture with water until a smooth cream without lumps is obtained. Transfer 

 this to a boiler capable of boiling 20 gallons, bring the volume of the cream to 

 20 gallons by the addition of water, boil and stir during half an hour. The liquid 

 should now be of a dark red colour ; if yellowish, continue the boiling until the 

 dark red colour is obtained, keeping the volume at 20 gallons. After the liquid h:?s 

 cooled, decant it from any small quantity of insoluble residue, and make up the 

 volume to 100 gallons with water. 



2. Carbolic Acid and Soft Soap. 

 Dissolve 5 lb. of good soft soap, with gentle warming, in 3 quarts of liquid 

 carbolic acid (containing not less than 97 per cent, of real tar acid). Mix the liquid 

 with enough water to make 100 gallons. 



3. Tobacco and Sulphur. 

 Steep 35 lb. of finely-ground tobacco (offal tobacco) in 21 gallons of water for 

 four days. Strain off the liquid, and remove the last portions of the extract by 

 pressing the residual tobacco. Mix the whole extract, and to it add 10 lb. of flowers 

 of sulphur. Stir the mixture well to secure an even admixture, and make up the 

 total bulk to 100 gallons with water. 



Note. — The period of immersion in these dips should not be less than half a 

 minute.
