It was shown how stimulus revived the pulsatory activity of Desmodium leaflet in a state of standstill, in the same way as it renewed the arrested growth-activity.
Growth is undoubtedly a pulsatory phenomenon; but under favourable circumstances, these merge practically into a continuous average rate of elongation.
It is often possible to obtain record of the pulsatory nature of growth-elongation.
In vigorous specimens stimulus induces the opposite effect by retarding or arresting the pulsatory activity or growth.

Thus the incidence of light on the pulvinule initiates pulsatory movements, which persists for a time even on the cessation of stimulus.
As the two opposing effects are nearly balanced, any fluctuation of the relative intensity of the two gives rise to the pulsatory movements often seen in the forenoon; the Mimosa leaf has moreover an autonomous movement of its own.
The occurrence of the pulsatory response in the morning record of Mimosa led me to search for multiple activity in the response of the pulvinus.
In connection with this I shall refer to the suppression of the pulsatory activity of Desmodium gyrans when the leaflet was pulled up by the action of light (cf.
Arrest of pulsatory movement of leaflet of Desmodium gyrans by light from above and gradual restoration on cessation of light.
It is manifested by such signs as subcutaneous emphysema, swelling of the neck, fever, irritability, increase in pulsatory and respiratory rates, and pain in the neck or chest.
The normal pulsatory movements are due to the pulsatile pressure of the aorta, found at the 4th thoracic vertebra (24 cm.
And here I may remark, that, although the conception of the undulatory current of electricity is entirely original with myself, methods of producing sound by means of intermittent andpulsatory currents have long been known.
The three primary varieties designated as intermittent, pulsatory and undulatory, are represented in lines 1, 2 and 3.
Thus our final conclusion is that during historic times there have been pulsatory changes of climate.
Hence the strongest of all the arguments against historic changes of climate seems to be of relatively little weight, and the pulsatory hypothesis seems to be in accord with all the known facts.
In the case of the pulsatoryhypothesis we are fortunately able to apply this test by means of trees.
Finally, the uniformity of the vast eons of the past and the tendency toward complexity are broken by pulsatory changes, first in one direction and then in another.
The considerations which have just been set forth have led to a third hypothesis, that of pulsatory climatic changes.
The odds and ends on the table beside him were rattling merrily, and a deep pulsatory humming rang stridently through the silence of the swamps.
Then he touched a valve, and the machine became animate with a low pulsatory wheezing, while something commenced to hum and rattle inside it.
