502 GENERAL DISEASES. 



unfrequently been communicated by the mangers of railway boxes 

 which had previously carried a glandered animal. 



Respecting the spread of glanders by public water troughs, Mr. 

 Hunting writes as follows : — " It is quite possible that some cases 

 of glanders have arisen as the direct effect of drinking at a 

 public trough, but they are very few and far between. I have 

 an intimate knowledge of the stables of three contractors who 

 have had, during the last twenty years, four outbreaks of glanders 

 in their studs. Each outbreak was clearly and directly traceable 

 to the purchase of a horse from an infected stud, and was stamped 

 out at once without spreading. Save these outbreaks, no glanders 

 has troubled them, and yet their horses travel all over London, 

 and drink at any water trough they can reach. I feel convinced 

 that infection from water troughs is very rare, because in 90 per 

 cent, of all outbreaks which I have personally investigated, other 

 methods of infection were traceable. Even if 5 per cent, of all 

 outbreaks in London were traceable to the water troughs, the 

 gravity of the harm would be no argument in favour of closing 

 the troughs, especially in summer. The harm resulting to 

 horses from being denied water all day, would cause a mortality 

 greater than is caused by all the glanders in the metropolis." 



When engaging new premises, especially in large cities, it is ad- 

 visable to be sure that they are free from the contagion of this 

 disease. 



ERADICATION OF GLANDEES.— The teaching of McFadyean, 

 Nocard, Hunting, and other authorities show that Government 

 should adopt the following rules, the first of which is the only 

 one in force : — 



1. To slaughter all horses which have outward syrtiytoms of 

 glanders (p. 500), and to thoroughly disinfect the stable or enclo- 

 sure occupied by such animal or animals. 



2. To test with mallein all in-contact horses, namely, those which 

 are in the same stable, field or other place as a glandered horse. 



3. To quarantine all reacting horses, and to submit them to fur- 

 ther mallein tests, with intervals of time which should not be less 

 than three weeks. A clean bill of health should not be given to 

 any tested horse, until it has ceased to react, preferably on two 

 consecutive occasions. Although it would be the safer plan to keep 

 the reacting horses entirely isolated, the small risk of allowing 

 them to go out and work might be disregarded, on condition that 

 they were not to enter any stable except their own. 



The following additional rules would greatly help the good work 

 in question : — 



4. Compulsory notification hy veterinary surgeons of all cases
