carbolic acid and potash, of each 1 kilo (cost, 13 to 14 francs). 

 This bath is very energetic, but its preparation requires some time, 

 and it may produce poisoning. 



5. The arsenical baths, commended by Tessier and Mathieu, have 

 been variously appreciated. Some have pointed out the dangers to 

 which they expose the animals, whilst others have insisted upon 

 their remarkable efficiency. The numerous poisonings which have 

 been observed have been due to neglect and imprudent manœuvres 

 rather than to cutaneous absorption ; they must, however, only be 

 used after the small wounds produced by the process of shearing 

 have healed ; shearing should, therefore, be performed eight to 

 fourteen days before the treatment. Tessier's bath has the follow- 

 ing formula: arsenous acid, 1| kilos; sulphate of iron, 10 kilos; 

 water, 100 litres.^ Mathieu replaces sulphate of iron by alum 

 (arsenous acid, 1 kilo; alum, 10 kilos; water, 100 kilos). This 

 last preparation is especially used in Wiirtemberg and some dis- 

 tricts of Bavaria. Kehm recommends a solution prepared with 

 J kilo of arsenous acid, 6 kilos of alum, and 100 litres of water. 

 It is necessary to dissolve the arsenous acid beforehand in boiling 

 water, in order to avoid the cauterizations which it may occasion. 

 Putscher^ uses also arsenical solutions, for which he prepares the 

 animals by a washing with black soap ; in order to obtain the cure 

 he was obliged to give three baths in every instance ; he advises a 

 nine days' interval between the baths. 



6. Frohner^s cresol bath, adopted by the German Government. 

 Shearing is not absolutely indispensable for the cresol treatment ; 

 mangy sheep with their fleece have been subjected to it with suc- 

 cess and without any damage to the wool. If the sheep are shorn, 

 the scabs of the most affected regions should be softened ; this is 

 done by making daily frictions for three to five days with a cresol 

 liniment (creolin 1 part, alcohol 1, green soap 8). These frictions 

 constitute an important element of the cure. 



1 In order to lessen the danger of poisoning, the solution has been rendered bitter 

 through the addition of gentian powder, and more recently with aloes. Trasbot's 

 arsenical bath, which at present replaces Teissier's bath everywhere, has the for- 

 mula (Codex of 1884) : 



J^.— Arsenous acid 1000 grammes. 



Sulphate of zinc (commercial) . . . . 5000 " 



Aloes ......... 600 " 



Water 100 litres.
