DISEASES AND THEIR TREATMENT . 



In spinal paralysis there is a loss of sensation and a constant drib- 

 bling of urine, and involuntary foecal passage. Temperature 102 to 

 103. No perceptible change of color in urine. In Azotaria the 

 animal has suddenly partial loss of sensation, the urine and fceces 

 not voided. No perceptible rise in tempei-ature. The urine, if 

 withdrawn from the patient, will be of a coffee brown color. The 

 animal is uneas}'^ struggling and sweating over the flanks, and in 

 great pain.

 the nostrils open, and the whole expression of the countenance 

 haggard and excited, evincing great suffering. (A good idea of 

 which is given by Fig. 802.)
