CoNTAGio-N. — Glanders does not seem to be a highly contagious 

 disease; cases are known where affected animals worked and stood 

 by the side of healthy animals for months without transmitting 

 the disease. Again, when once introduced into the stables, it is 

 certain to spread among the horses there located. The vitality, 

 of the virus is wonderful, as it may be dried in air, remain in that 

 condition for years, and on being rendered fluid is found to retain 

 its virulence. The virus may be taken into the nasal chambers 



in the form of dust, and on be- 

 coming moistened by the secretions 

 inoculate itself. 



Period of Incubation. — The 

 period of incubation is short. It 

 generally shows itself in connection 

 with the submaxillary glands on the 

 third day after inoculation, and the 

 discharge from the nostrils occurs 

 from the third to the sixth day. In 

 some cases it does not appear for a 

 much longer period. 



Symptoms of Acute Glanders. — 

 The disease is ushered in by rigors, 

 usually followed by a discharge and 

 ulceration of the mucous membrane 

 of the nose. The temperature is as high as 106°, or some- 

 times as high as 109°. The breathing is aifected, the 

 appetite fails, and the eyes are afl"ected. The principal diag- 

 nostic symptoms, however, are connected with the nasal cham- 

 bers. There will be an abundant discharge from the nostrils of 

 a fetid nature. The pituitary membrane at first is of a dark 

 copper color, with patches of ecchymosis of a dark red hue. It 

 gradually becomes paler, and the patches are rapidly converted 

 into pit-like, ragged-edged ulcers, from which issues the dis- 

 charge. The submaxillary lymphatic glands enlarge. Other
