Walz's dip, one of the oldest recipes, i§ as follows : Take of fresh 

 slaked lime 4 parts, carbonate of potash 5 parts, mix and boil in barn- 

 yard water; add animal oil G parts, tar 3 parts; dilate with barn-yard 

 lees 200 parts, water 800 parts. To-day this recipe is more curious than 

 useful; one of the ingredients is not on tLie American market, and an- 

 other is offensive. Veterinarian Clok, in his Diseases of Sheep, 1861, 

 reports this mixture as being too we^ik for old cases, and recommends 

 the following moditicatiou: Take of freshly-burned slaked lime 6 

 pounds, add potash 6 pounds, and water 10 quarts ; boil an hour, stir- 

 ring occasionally. Add pine-oil 8 pounds, and tar 2 quarts, stirring the 

 mixture thoroughly. Make an infusion of 20 pounds tobacco in 130 

 quarts of water; add the lye already made and stir. This quantity suf- 

 fices for one hundred sheep. Apply by immersing the sheep, separat- 

 ing the wool and breaking the scabs. Eepeat in eight or ten days. 



Law's recipe (Farmers' Veterinary Adviser) is a very good one : Takes 

 of tobacco 16 pounds, oil of tar 3 pints, soda ash 20 pounds, soft soap 4 

 pounds, water 50 gallons. This quantity suffices for fifty sheep. The 

 tobacco should be steeped ; afterward the other ingredients should be; 

 added at 70° Fab. 



Zundel's dip is available, but Dr. Kaiser (Kuhrverfahren bei derSchaf- 

 riiude, 1883) reports that it is too weak in cases of long standing. It is 

 said to leave the wool clear and white after using. For every one hun- 

 dred sheep take crude carbolic acid 3 pounds, caustic lime 2 jjounds, pot- 

 ash 6 pounds, black soap 6 pounds, and water 70 gallons; mix and boil. 

 Dr. Kaiser has obtained excellent results from a modification of this 

 recipe. Take of tobacco 5 kilograms (13^ pounds), infuse it in 250 liters 

 or 66 gallons water; dissolve in it 3 kilograms (8 pounds) soda, add IJ 

 kilograms (4 pounds) freshly burned and slaked lime. Dilute 3 kilo- 

 grams (8 pounds) black soap (soft soap will do) with hot tobacco broth 

 and add it to the rest; then add H kilograms (4 pounds) crude carbolic 

 acid, which contains at least 50 per cent, of the pure acid. Mix. This 

 quantity is suflicient for one hundred sheep. 



Gerlach's dips, which are administered at two different times for a 

 single treatment, are cheap, but owing to the time and labor to be ex- 

 pended in performing an operation twice which in other instances is 

 done but once, is much more costly than those which require but one 

 application. 



Take of potash 2 parts, burnt lime 1 part, water 50 parts. Mix. Use 

 this dip for softening scabs. Follow it in two or three days by the fol- 

 lowing : Make an infusion of tobacco 34 pounds in 66 gallons water, by 

 slowly steeping the tobacco in a portion of water and finally adding it 

 to the remainder, liepeat the dip in from six to ten days. 



Roloff's dip, for a mixture sufficient ft)r one hundred sheep, is : Take 

 7.5 kilograms (20 pounds) of tobacco, steep it with 250 liters (66 gal- 

 lons) water for half an hour, iieat it to 30^ R. (95^ Fah.) and add X 

 kilogram (2^ pounds) each of pure carbolic acUt am] of potash.
