GLANDERS AND FARCY. 237 



diabetes insipidus or polyuria. It cannot be said that in diabetes 

 there is any obstruction to the excretion of degraded tissue ; 

 indeed, the reverse is the case, excretion of urine being enor- 

 mously increased. If we look deeper into the matter we shall, 

 however, see that the polyuria is associated with rapid tissue 

 changes, rapid emaciation of the body being a most prominent 

 symptom, with debility arising from degradation of tissue, and 

 i'rom the presence of the degraded materials within the cir- 

 culatory fluid. So apparent is this condition, that it has been 

 truly said that diabetes, when arising from no cognizable 

 cause, is often indicative of a general breaking-up of the con- 

 stitution. 



Although glanders and farcy are one and the same disease, 

 differently manifested, farcy is apparently more frequently de- 

 veloped spontaneously than glanders. This circumstance; and 

 the possibility of recovery from mild attacks of farcy, has led 

 some to conclude that they are two separate disease ; but direct 

 experiment has proved that the virus is identical in both forms 

 of the disease. The discharge from the nose of a glandered 

 horse, when introduced into the systems of other horses, may in 

 one produce glanders and in another farcy, whilst the pus from 

 a farcy ulcer may produce in the inoculated animal glanders, 

 farcy, or both ; and the common termination of farcy, if a horse 

 affected by it be allowed to live a sufficient length of time, is 

 glanders, and of glanders farcy. Such an animal is described as 

 being " both glandered and farcied." 



CONTAGION. 



Glanders, and its variety farcy, are highly contagious and 

 infectious, and when once introduced into a stable are almost 

 certain to spread amongst the horses there located. 



As already stated, the contagium is found to be an aerobic 

 bacillus discovered by La3ffler and Schlitz, 1882, called the 

 Bacillus mallei. These organisms are seen in the form of 

 minute rods f oixro- long, and from -^-^^jjjj to -^jtI^-q of an inch 

 Ijroad ; they are rather thicker than the tubercle bacillus, and 

 retain the methylene blue stain. They are found in the nodules 

 in the lungs, liver, Schneiderian membrane, and other involved
