the organism through the point. We have several times had these

NEWER PHYSIOLOGY AND PATHOLOGY.
By Prof. SAMUEL BELL, M.D.
Physiology has for many decades been a science founded on experiment,
and pathology has been rapidly pressing forward in the same direction.
To read the accounts of how certain conclusions have been arrived at
in the laboratory, by ingenious devices and by skillful manipulations,
is as fascinating as any tale of adventure.
When the microscope began its work, how discouraging was the vastness
and complexity of the discoveries which it brought to light; how many
years has it been diligently used, and how uncertain are we still
about many of its revelations! But what a happy conjecture of man, and

give an illustration:
Some thirty years ago, Virchow began his studies and lectures upon
cellular pathology.
