THE ORDER OF SHAKES— OPHIDIA. 
It must be borne in mind that we only deal with Australian snakes, 
not with American, African, or Asiatic species of the family Viperidce, 
which have a large number of labial shields. 
The Death Adder {Acanthophis antarctica )—intermediate between 
the Viperine and the Colubrine Venomous Snakes—has seven lower 
labials, but never more than six upper ones.

The abdominal or ventral plates are counted from the chin shields 
to the vent, winch is covered by one or two plates; below this the sub- 
caudal plates commence, in one or two rows. 
A few concluding remarks on snake poison, and the treatment of 
wounded persons, will perhaps be acceptable to many readers. A great 
deal has been written upon this subject of late, but with little benefit to 
the general public. The antidote vendors and their supporters have, how¬ 
ever, been thoroughly exposed, and fresh experiments only prove that some 
animals will die in spite of every remedy, and others recover without physic. 
Injections into the blood have been recommended, but ignorant 
persons were not cautioned against the danger of the experiment; and 
in the hands of the unskilled, the cure may prove to he worse than the 
disease. Doctors are not alwuys present in places wnere dangerous snakes 
abound; it is necessary, therefore, to consider what should be done when 
a wound has been received by a person who cannot obtain scientific
