If coagulable l}Tiiph forms, threatening callosity, (a hard swelling; 

 daily and long-continued friction — hand rubbing downward — and the 

 application of a more decided stimulant will be indicated. If so, prepare 

 the following: 



No. 151. 1 Ounce oil of cedar, 



1 Ounce oil of majoram, 

 1 Ounce oil of sassafras,

Causes. — This is a sprain of the flexor tendon behind the hock, and 

 which has a large sheath which extends both above and below the joint — 

 a dropsical enlargement of the sheath of the tendon, so the fluid con- 

 tained may be pressed from one side to the other. Hence its name. 



How to know it. — Pressure on one side will cause bulging on the other, 

 and pressure on both sides will cause fluctuation along the tendon below 

 and behind the hock. 



What to do. — Use the same treatment as for curb ; cold water band-

ages, or hot fomentations in the early stages of the disease ; also absolute 

 rest and a high-heeled shoe. When tenderness ceases and lameness is 

 gone, apply a spring truss, so the pads will clasp and cover the puff on 

 both sides, and exert a pretty firm and steady pressure. Success in re- 

 moving the puff has occasionally been had by puncturing the lower part 

 of the swelling, into the sack, and injecting a solution of the following 

 strength : 



No. 152. 10 Grains sulphate of zinc, 



1 Ounce rainwater. 



Inject one or two tea-spoonfuls, as the case may require. Then bring 

 the walls of the sack closely together and hold them so for a week by 

 means of a firm flannel bandage. 



Another plan is to apply with gentle rubbing, the following ointment 

 every day until ihe skin is inflamed : 



No. 153. 1 Part biniodide of mercury, 



7 Parts neats foot oil. 



Rub together, either in a mortar or with & spatula on glass, until ina- 

 ■aatcly incorporated, and use as directed, observing regularity and slnu^ning 

 "^lent handling.
