inevitable occurs, but we realize the difficulties, expense, 

 inconvenience, and utter inability to successfully carry it 

 out unless the owners are willing and anxious to assist, 

 and the latter is hardly to be looked for in a scheme 

 which is a charge, perhaps a heavy one, against the 

 proprietor. 



The above method of dealing with ' reactors ' was sug- 

 gested by the Departmental Committee on Glanders of 

 1899, and presumably it knew of the practicability of the 

 scheme it recommended, in fact it is known to be the plan 

 on which certain infected studs have been successfully dealt 

 with, though it would present perhaps great difficulties to 

 the small owner. 



By the regular malleining of such an isolated stud it 

 might be possible in several cases to effect a cure, while 

 the clinical cases could be picked out at the periodical 

 inspections. 



Such a scheme as the one put forward provides against 

 the further infection of the healthy stock, but it is obviously 

 weak in some essential points of which the most fallible is 

 the personal equation. 



Isolation is a difficult matter unless two distinct buildings 

 are obtainable ; without this the sources of leakage from 

 indifference and neglect will be very great, and the object 

 possibly defeated. 



Eradication. — On an outbreak of glanders occurring, the 

 first thing to do is the selection of all clinical cases by in- 

 spection. For this latter purpose the nasal chambers must 

 be illuminated by means of a mirror, without which no 

 thorough inspection is possible. On dark days an electric 

 lamp should be so arranged as to have its light reflected up 

 the nose. 



After the destruction of all clinically affected, the stud 

 should be arranged in batches for mallein testing, but it is 

 a sound precautionary measure not to mallein at once, but 

 rather to wait for a month, so as to prevent the most 

 recently infected cases escaping observation by failing to 

 react. It is obvious that a horse infected two or three days
