DISEASES. 693 



by Defays. Tor this there must be no wound, and the cavity 

 must be well cleaned of all substances, or even washed with ether 

 to remove aU greasy substances which would prevent the gutta 

 percha from adhesion with the hoof. This course has enabled us 

 to see deep seedy toes recover by the gradual growth of the foot. 

 Hence, the indication to try to obtain an artificial seedy toe as 

 early as possible, as recommended by Hertwig. 



When there is thickening of the keraphyllous horn and adhes- 

 ion with the waU ; when, also, the toe is formed entirely by a de- 

 formed horny mass, the case is more serious and the treatment 

 more uncertain. It has been recommended, wrongly, we believe, 

 to perform the operation which consists in cutting off all the pro- 

 truding hoof — to even cut off all the accidental production. To 

 do this the rasp and drawing-knife are used, the keraphyllous mass 

 being thrown down as much as possible. D'Arboval has also ad- 

 vised to make with the drawing-knife an artificial seedy toe be- 

 tween the internal face of the wall proper, which is preserved, and 

 the anterior face of the podophyllous apparatus, upon which a 

 thin layer is left. This treatment has an advantage over the other 

 of keeping the wall intact, to render easier and more solid the 

 application of the shoe which is to protect the foot and allow the 

 animal to resume his work. This operation, however, is only pal- 

 liative. It, however, gives great relief, especially in the first steps 

 of chronic laminitis. 



Gross has been satisfied with thinning down with the rasp the 

 superior part of the wall, below the coronet, in a width of about 

 four centimeters, in such a way that from one heel to the other 

 there was only a very thin coat, which he protected with basilicon 

 ointment. The coronet was then stimulated with a little oil of 

 cantharides. Under this treatment, a new growth of hoof is 

 started, not so protruding, and by paring down by degrees the 

 hoof, a new foot was grown in a few months, less deformed and 

 more regular. 



Meyer and Gunther say that they have obtained good success 

 with this treatment, which nearly resembles that of Gohier and 

 Dehan, except that with those the entire wall was pared down to 

 a thin pellicle, flexible under the pressure of the finger. Silber- 

 man advised to place around the hoof, below the coronary band, 

 after paring it down thin, a band of steel, two fingers wide, which 

 could be tightened by a screw placed at the heels. In this way
