in the response of the muscle, but after successiveapplications of pressure there was no increase intension above the control value. It was further ob-served that if a muscle, when immersed in an oxy-genated normal Ringer's solution, was fatigued byrepeated stimulation, its response under pressure wasless than the control, i.e., the action of pressure onthe tension developed by the muscle in response to asingle stimulus is opposite in direction to its actionin a fresh preparation. It seems probable that oxygenlack and acid solutions produce their effects by pro-moting fatigue. The following points have beenestablished regarding the reversal of the pressureeffect in the fatigued muscle: (1) The degree ofdepressed is roughly proportional to the pressureemployed. (2) The tension developed by the fatiguedmuscle is commonly reduced to about one half by apressure of 1,600 pounds per square inch. (3) Theresponse very quickly, possibly instantaneously, re-turns to the control value when the pressure is re-leased.

In the case of cardiac muscle the stimulating action,of pressure on the tension can no longer be obtainedwhen the temperature is reduced to 50 C., and wehave secured some evidence of a reversal occulrring atthat point. (In press, American Journal of Physiol-ogy.) Studies now in progress on striated muscleindicate that there is a critical point at approximately130 C. at which the stimulating action of pressurepasses into depression. At a few degrees below thistemperature the depressive action becomes markedand becomes greater as the pressure is increased. Afew preparations have shown, in the vicinity of thecritical temperature, a stimulation under the lowerpressures (1,000 pounds) and depression at higherpressures (2,100 pounds). As the temperature is low-ered pressure causes a further reduction in the re-sponse until at about 1° C. high pressure (2,100pounds) almost completely suppresses the develop-ment of tension. At room temperature the magnitudeof the response of the muscle continues to increasewith increasing pressure up to at least 2,100 poundsper square inch, which is the greatest pressure wehave employed.When pressure is released the muscle again re-

sponds with the development of tension, the recorddiffering in no way fromn the control taken before theapplication of pressure to the cold muscle. Whensuch a muscle is warmed to room temperature, pres-sure once more causes an increase in the developmentof tension corresponding closely with the result ob-tained before the muscle was chilled.

MIeasurements of the duration of the phases of con-traction and relaxation of cardiac muscle show that

moderate pressures result in only a slight prolonga-tion of these periods, and the same appears to holdfor striated muscle at room temperature. On the otherhand, at the lower temperatures pressure causes, alongwith the depression in tension development, a strikingprolongation in the duration of the phases of contrac-tion and relaxation which, for the higher pressures,may reach 100 per cent.

Certain interesting differences of behavior betweencardiac and striated muscle are indicated by theseresults. In the first place, it appears impossible tofatigue cardiac muscle in such a manner as to pro-duce a reversal of the pressure effect such as occursin striated muscle, and in the second place the criticaltemperature, in which reversal of the pressure effectoccurs, is about 80 C. lower in cardiac muscle.The significance of these results in relation to the

mechanism of muscular contraction will be discussedat a later date in connection with the publication ofthe complete data.

SUMMARY

The usual augmenting action of pressure on thetension developed by striated muscle in response toa single stimulus changes to depression on fatiguingthe muscle. On release of the pressure the tensionof the single twitch again reaches the control value.A similar reversal may be brought about by cooling

the muscle, the change usually occurring at about13° C. Below this temperature the depression isroughly proportional to the pressure. At about 1V C.the tension development may be completely inhibitedby high pressure. The muscle responds normallyupon release of the pressure, and upon warming pres-sure again causes augmentation of contraction.

CCURATE measurement of refractiveindices and dispersions of fluids, solid andplastic bodies can readily be determinedwith the Bausch & Lomb Abbe Refractome-ter. Because of its simplicity, ease ofoperation and the importance of its find-ings it is widely used in chemical and phys-ical laboratories.

This instrument measuresrefractive indices rangingfrom nD 1.3 to 1.7. An ac-curacy of one or two units inthe fourth decimal place can

be obtained. Charts supplied with each in-strument enable dispersion readings to betaken with the same accuracy. The index isread directly on a sector scale, the intervalsof which have been calculated for the con-stants of the glass used in the Abbe prisms.

Refractive index is a valuablefactor in the determination ofthe strength and purity of so-lutions, the proportion of mix-tures of two liquids, the per-centage of foreign matter ina liquid or solid, etc.
