The following is a sketch of the work of Professor Pawlow on conditioned reflexes, of Orbeli on the sympathetic nervous system, and of the new work of Speransky on pathology of the brain.

Let it be said at the outset that, although it is easy to grasp the principles on which the work of conditioned reflexes has been built and to understand a simple experiment, the comprehension of the whole subject is extremely difficult.
