though, for obvious reasons, young creatures are more dispos 
thereto as a sequel to many maladies, especially from distempe 
Commonly the history of a case is most indefinite. Could fl 
desired information be obtained, it would probably be somethil 
as follows: Restlessness, followed by shaking of the head, ind! 
ative of tinnitus aurum , sudden manifestations of deafness, p 
tial or complete, succeeded by a brief period of excruciati 
pain. Unfortunately, these stages are commonly past ere scic 
tific aid is invoked, and shaking of the head, upon which so mu 
stress is often laid, does not again appear save as pus irritates t

sensation. Even a febrile condition may be difficult to establie 
except by visiting the creature at unusual hours, the pulse ai 
thermometer alike failing to register any marked disturbance

speculum and mirror will establish the fact; the great difficulty 
employing either being to get the animal in position favorable 
light. 
Mastoid pain when present is commonly so severe and peculi

and occipital regions of the affected side, and its seat is with difl
