Official Notices and Circulars. 



[JAN.. 



It has been proved that double dipping with an interval of not more 

 than 14 days between the dippings is a necessary measure to secure the 

 eradication of Sheep Scab, and that when proper precautions are taken 

 such dipping can be carried out with little risk even when poisonous 

 dips are used for each dipping. All risk, however, can be avoided by the 

 use of non-poisonous dips, of which the lime and sulphur dip (see footnote 

 as to Ingredients, etc.), is considered the best for the cure of Scab. 



I am, therefore, to suggest to your Local Authority that when double 

 dipping with an interval of not more than 14 days between the two 

 dippings is prescribed, either by an Order of the Board or by a Notice 

 issued under any Order of the Board, the owner or owners concerned 

 should be warned that it is always safer to use non-poisonous dips, 

 and if they elect to use a poisonous dip for the purposes of the first 

 dipping it is higlily advisable that for the purposes of the second dipping 

 a non-poisonous dip should be used. There are, of course, many 

 non-poisonous dips on the market which have been approved by the 

 Board for the purposes of their Orders relating to Sheep Scab and Sheep 

 Dipping. I am, etc.,

 Prescription for Lime and Sulphur Dip. 



Ingredients. — Lime, powdered sulphur and water in the proportions 

 indicated above. 



A convenient quantity for a large establishment to make up at a time would 

 be 9 lb. lime and 18 lb. sulphur. 



Method of Preparation. — Slake the lime and make into a thick paste with 

 the sulphur. Place the mixture in a strong cloth, tie the ends and suspend 

 in a boiler containing 10 gal. of water so that the water completely covers the 

 contents of the cloth. The cloth must not touch the sides or bottom of the 

 boiler, as otherwise the cloth may be burned and its contents escape. BoU for 

 two hours, then remove the cloth, taking care that none of its contents 

 escape into the water, and throw the solids away. Make up to 10 gal. again 

 with additional water, and put the liquid into a tight drum or barrel. This 

 quantity is sufficient when mixed with water to make 100 gal. of dipping bath. 

 The period of immersion in this dip should not be less than half a minute. 



Since the Note was published in the issue of this Journal for last 

 month, summarising the position as regards Foot-and-Mouth Disease 

 in Great Britain, all the remaining general 



Foot-and-Mouth restrictions have been withdrawn from the 

 Disease. Surrey and ten Isle of Wight Scheduled 



Districts, no outbreaks of the disease having 

 occurred therein since 12th and 24th November respectively. In 

 Wanvickshire a small area still remains subject to a Prohibition|^Move- 

 ment Order on account of the outbreak of the disease near Rugby on 

 15th December. Outbreaks have unfortunately appeared in six fresh 

 centres during the past four weeks, and the position as regards each 

 centre, and of the Durham outbreak notified last month, is as follows : — 



Durham. — Further outbreaks on premises about 5 miles from the 

 original centre were confirmed on 3rd January at Sherburn Hill and 

 Shadforth, and on 7th January at Shadforth. These three cases were 

 connected. The restrictions on movement and marketing of stock have 

 been modified as regards a large part of the Scheduled District, but no 

 movement out of the district is permitted. 



West Sussex. — ^An outbreak was confirmed at Harting on 22nd Sep- 

 tember, and the usual Order entirely prohibiting movement within 

 a radius of about 15 miles was made. There has fortunately been no 

 extension of the disease in this locality, and the general restrictions 

 have been modified.
