different tissues, while even the same poison, according to the dose
administered and other conditions, expended its toxic activity in
different ways.

Further, the allotropic modifications of elements and the isomerism of
compounds increased the difficulties. Why should yellow phosphorus be
an active poison and red phosphorus be inert? Why should piperine be
the poison of all poisons to keep you awake, and morphine the poison
of all poisons to send you asleep, although to the chemist these two
bodies were of identical composition? The lecturer urged that the
science of medicine (for the poisons of the toxicologist were the
medicines of the physician) must be experimental. Guard jealously
against all wanton cruelty to animals; but to deprive the higher
creation of life and health lest one of the lower creatures should
suffer was the very refinement of cruelty. "Are ye not of much more
value then they?" spoke a still small voice amid the noisy babble of
well intentioned enthusiasts.--_London Times._
