decubital positions; the nerve is squeezed between the thorax and the 
leg, specially if this one is in crossed position. It may arise from other 
causes (traumatisms, fractures, tumors). Goubaux accuses falls and con- 
tusions ; Tondeur has recorded a case due to a kick. Sometimes it arises 
from strong and repeated contractions of the muscles, which the nerve 
ramifies (Werner), or from struggles made to relieve himself from hobbles 
(Weber). Benjamin has treated a six year old horse, phlethoric, taken 
with paresis while working: harnessed to a heavy load and obliged to 
make violent efforts, the horse suddenly fell, could not rise except with

difficulty, and presented symptoms of cerebral hyperemia, of inco-ordina~ 
tion of motions in the anterior extremities, and lastly in the right leg, and 
the functional troubles resulting from incomplete paralysis of the radial. 
Often this becomes manifest after a quick and longrace. Brauer has 
seen it after a long exposure to cold rains (rheumatismal paralysis). Th 
one horse at our clinics, it occurred at night, probably from defective atti- 
tude or from a slip. Bowmann and Brauer have related cases of double 
radial paralysis, occurring suddenly. Méller has seen that of the left 
nerve to be complicated in a few days with that of the right. In a case
