hat two colourless
liquors may produce a colour by union, and that two cold bodies will
grow hot if they are mingled; they mingle them, and produce the effect
expected, say it is strange, and mingle them again.

The Idlers that sport only with inanimate nature may claim some
indulgence; if they are useless, they are still innocent: but there are
others, whom I know not how to mention without more emotion than my love
of quiet willingly admits. Among the inferior professors of medical
knowledge, is a race of wretches, whose lives are only varied by
varieties of cruelty; whose favourite amusement is to nail dogs to
tables and open them alive; to try how long life may be continued in
various degrees of mutilation, or with the excision or laceration of the
vital parts; to examine whether burning irons are felt more acutely by
the bone or tendon; and whether the more lasting agonies are produced by
poison forced into the mouth, or injected into the veins.

It is not without reluctance that I offend the sensibility of the tender
mind with images like these. If such cruelties were not practised, it
were to be desired that they should not be conceived; but, since they
are published every day with ostentation, let me be allowed once to
mention them, since I mention them with abhorrence.

Mead has invidiously remarked of Woodward, that he gathered shells and
stones, and would pass for a philosopher. With pretensions much less
reasonable, the anatomical novice tears out the living bowels of an
animal, and styles himself physician, prepares himself by familiar
cruelty for that profession which he is to exercise upon the tender and
the helpless, upon feeble bodies and broken minds, and by which he has
opportunities to extend his arts of torture, and continue those
experiments upon infancy and age, which he has hitherto tried upon cats
and dogs.

What is alleged in defence of these hateful practices, every one knows;
but the truth is, that by knives, fire, and poison, knowledge is not
always sought, and is very seldom attained. The experiments that have
been tried, are tried again; he that burned an animal with irons
yesterday, will be willing to amuse himself with burning another
to-morrow. I know not, that by living dissections any discovery has been
made by which a single malady is more easily cured. And if the knowledge
of physiology has been somewhat increased, he surely buys knowledge
dear, who learns the use of the lacteal
