Among the internal remedies which may be employed with good effect in certain cases are aconite, bromide of potassium, and Indian hemp. ...

The impulse passes thence to the medulla, and so reaching the sensory centres starts a feeling of pain that radiates into the chest or down the arm. There are three main varieties:—(1) the reflex, (2) the vaso-motor, (3) the toxic. ...

... center. That does not mean that a subconscious mind is listening while my lucid mind was thinking, but it does mean that those words were unattended and remained in the periphery of the field of consciousness. But when some of the sentences stirred up in that peripheral field some important associations, they were strong enough to produce a new motor reaction by which the mental equilibrium became changed again and by which the lecturer overwhelmed my private thoughts.

This difference explains how it is that the image, while resulting from a physical impression, may yet be in a great number of cases declared ...

Figure 193 C shows the yolk transformed into the embryo (g), with the outer layer of blastodermic cells (b). The body of the germ is infolded, so that the embryo appears bent on itself. ...
