surface and renew it with fresh material ; the portion 

 removed being well mixed with quicklime is buried six 

 feet in the ground, and, if possible, in some waste place 

 where permeation is least likely to take place. 



12. In a stud where an outbreak has occurred it 

 should be considered infected until at least six months 

 has elapsed from the date on which the last case was 

 either separated from the healthy horses or discharged 

 cured when treatment has been adopted ; further, the 

 horses of the stud should be kept under observation 

 {i.e., their movements carefully reported, so that they 

 are not lost sight of) for another six months. 



13. In dealing with outbreaks of this disease it 

 is advisable to extirpate all suspicious indolent sub- 

 cutaneous nodules, whether the animal is known to 

 have the disease or not, as they may possibly contain 

 the cryptococcus. Having recourse to this method 

 has the advantage of greatly reducing the number of 

 animals under observation, and does away with a great 

 deal of unnecessary isolation of many horses which are 

 free from the disease. 



14. When the disease makes its appearance in a 

 large stud farm or remount depot, where young stock 

 have been running out, it is advisable to have all the 

 animals taken up, and either put in stables or picketed 

 out in batches of about 50 to 100, each animal being 

 well clear of the other, so that they cannot kick or bite 

 one another, and issues should only be made from 

 batches which have been for at least six to twelve months 

 clear. All the animals should, after due quarantine, 

 be issued from the stud, and the stables should then 

 be all thoroughly disinfected as already mentioned, the 

 land should be dressed with quicklime, which may 

 be either left to penetrate itself when the rain comes, 

 or be ploughed in and the land then cropped. Even
