V.—Errect or VENOM ON THE NERVOUS SYSTEM. 
The venoms of all snakes directly, or indirectly affect the nervous 
system. The introduction of snake poison is followed by depression, : 
faintness, loss of co-ordinating power, and ultimately by paralysis : 
These symptoms point to alteration in either the nervous centres 
or the peripheral nerves. 
Brunton and Fayrer concluded, from their experiments, that 4 
the peripheral termination of the motor nerves were actually 
paralysed by cobra venom. These authors repeated Claude 
Bernard’s classical experiments by means of which he demonstrated 
that curare paralysed the peripheral terminations of motor nerve ’ 
The results with cobra venom showed that this poison exerted & ; 
similar effect. They were however, of opinion that paralysis ¢ ; 
motor nerves was not the only effect of cobra poison oP oe 
nervous system, but that the spinal cord was also paralysed. a 
some instances paralysis of the spinal cord appeared to cause 
death, when little or no affection of the motor nerves could be 
observed, but in other cases the peripheral paralysis was So? — 
marked. They thought it was doubtful whether the ete 
was directly affected by the poison, as the intelligence both = 7 
man and in animals often remained unimpaired to the last, a a
