If the transference of the erogenous excitability from the clitoris to the vagina has succeeded, the woman has thus changed her leading zone for the future sexual activity; the man on the other hand retains his from childhood.
We thus discover incidentally that a certain amount of sexual tension is itself necessary for the excitability of the erogenous zones.
Where there is no stock of semen it is not only impossible to accomplish the sexual act, but there is also a lack of excitability in the erogenous zones, the suitable excitation of which can evoke no pleasure.

Mrs. Lyddell, though less ill, was not materially improved as regarded the excitability of her spirits.
The restlessness, the varied and almost incessant movements, and the peculiar excitability of the dancer have repeatedly suggested to casual observers the question, why does it move about in that aimless, useless fashion?
The seeming reduction which appears under certain conditions should be attributed, not to visual dizziness, but in part to excitability and restlessness, and in part to a reduced muscular power" (31 p.

We shall now proceed to inquire whether the response of inorganic bodies is affected by chemical reagents, so that their excitability is exalted by some, and depressed or abolished by others.
The excitability of B is depressed by a few drops of strong potash or oxalic acid.
This difficulty as regards the obtaining of response was overcome in the method of negative variation, where the excitability of one end was depressed by chemical reagents or injury, or abolished by excessive temperature.
There are other chemical reagents, on the other hand, which produce the opposite effect of increasing the excitability and causing a corresponding exaltation of electric response.
The above results show in what manner the excitability of the wire is enhanced by purely physical means.
A stimulus thus produces a state of excitability which may sometimes be expressed by change of form.
To determine the influence of a reagent in modifying the excitability of the tissue, we rely upon its effect in exalting or depressing the responsive E.
We may thus by reducing or abolishing the excitability of one end by means of suitable chemical reagents (so-called method of injury) obtain response in metals without a block.
Again a resultant differential action may be obtained even when the disturbance reaches both A and B, if the electrical excitability of one point is exalted or depressed by physical or chemical means.
The entire length of the wire may then be stimulated and a resultant response will be produced, owing to the difference between the excitability of the two ends.
The excitability of A is now depressed by oxalic acid.
Gradually, however, as my health improved with rest, this morbid excitability disappeared, and has never been renewed.
Sometimes the moderation of nervous excitability thus effected permits indulgences of the appetite for food that were impossible during earlier years--the nervous dyspeptic can tolerate dainties which would formerly have been unendurable.
The extraordinary muscular excitability manifested by these subjects is further illustrated by an observation recorded by Dumontpallier.
There is no exaggeration of the tendinous reflexes, and muscular hyper-excitability is absent.
His excitability appears to him a mark of superiority; he believes himself to be possessed by a peculiar insight lacking in other mortals, and he is fain to despise the vulgar herd for the dulness and narrowness of their minds.
This excitability can be equally manifested during fatigue.
Inadequate excitability may moreover be a property of the sensory nerves.
This increased excitability is, however, only one of the forms of the phenomenon of nervous debility.
The morbid mobility of his mind, the excessive excitability of his imagination, conveys to his consciousness all sorts of queer and senseless ideas.
The abnormal excitability of these parts of the nervous system can have as a consequence both an especial attraction towards woman and an especial antipathy to her.
The torsional response is, moreover, shown to be determined by the direction of incident stimulus, and the differential excitability of the organ.
Hence the effect of rise of temperature is complex; it enhances the excitability which favours contraction, while tending to oppose this contraction by the induced physiological expansion.
Traces of coal gas are known to enhance the phototropic excitability of an organ while continued absence of oxygen is found to depress it.
The records show that stimulation did enhance the excitability of the organ to a small extent.
In the pulvinus of Mimosa the geotropic excitability of the lower half is greater than that of the upper half.
The responsive torsion is determined by the direction of incident stimulus, and the differential excitability of two halves of the organ, the torsion being such that the less excitable half of the organ is made to face the stimulus.
The following table shows the enhancement of excitability of Mimosa at different temperatures, the testing stimulus being the same.
But it nearly vanishes when the excitability of the specimen is high, and the two opposite reactions succeed each other too quickly for the preliminary A reaction to become evident.
The only difference between the two organs is in the lesser excitability of the pulvinus of Cassia, on account of which a greater intensity of shock is necessary for producing the responsive fall.
It is however much better to take advantage of the natural difference of excitability of two different areas in the organ as in the pulvinus of Mimosa.
The object of this was to make due allowance of possible variation of excitability of the organ during the course of the experiment.
In the mechanical response of the pulvinus of Mimosa, the geotropic excitability was, however, found to be greater in the lower half than in the upper (p.
The effect of unequal excitability in different zones of the organ.
It came prompt, as usual, but with a promptitude, we felt disposed to flatter ourselves, inspired by other feelings than mere excitability of nerve and vehemence of intent.
She sneered slightly in saying this: nervous excitability was not much to Madame's taste.
There was a mechanical over-excitability of the muscles, and a slight exaggeration of the bone and tendon reflexes.

These authors found amongst twelve patients, three normal reactions and one instance of hypo-excitability amongst four subjects who, by other tests, failed to show vestibular disturbance.
And, on the contrary, when the action of these powers has been exerted with violence, or for a considerable time, the excitability becomes exhausted, and less fit to receive their actions.
The first will comprise those diseases in which the excitability is sufficiently abundant, or even accumulated, but where the excitement is deficient from a want of energy in the exciting powers.
The excitability is first exhausted, and then the stimulus is withdrawn.
He states that "the Brown-Sequard phenomenon is nothing more or less than a specific instance of the scratch-reflex," and it is due to a raised excitability of the mechanism of this reflex.
This raised excitability is the character acquired as a consequence, for instance, of the removal of part of one great sciatic nerve.
The nature of this raised excitability and its causation are discussed and elucidated, but this part of the work is not essential to the present consideration.
