States that the males not only never assume the plumage of the female after having once at 

 tained the masculine livery, but that young birds molt directly into a plumage approaching 

 that of the adult males.

Henry G. Beyer. The influence of variation of temperature upon the rate and 

 work of the heart of the Slider Terrapin, Pseudemys rugosa. 



Proc. U. S. Nat. Mus.,xui, July 13, 1885, pp. 225-229. Plates xv-xvi. 



In this paper, which is but a preliminary account of the subject, it is conclusively shown by 

 experiment that, although the rate of the heart moves with the temperature of the blood 

 which circulates through this organ, the work done increases with that temperature only up 

 to a certain limit, and then rapidly goes down. Tliis limit may be found different for the dif- 

 ferent animals. Heat being, no doubt, a musculo-motor stimulant, the decrease in the work 

 done by the heart consequent upon passing blood of an abnormally high temperature through 

 it, must be conceived as due to exhaustion from over stimulation of the musculo-motor ap- 

 paratus. 



It was found in these experiments that, when blood of comparatively high temperature was 

 allowed to circulate through the heart, that the latter is moreover considerably reduced in 

 volume, and both systole and diastole are shortened. Blood of a lower temperature, on the 

 contrary, caused a very marked prolongation of the diastole and systole, and also a very decided 

 increase in the volume of the heart. 



Blood of low temperature, therefore, though reducing the rate and the work done in a given 

 time, by prolonging the diastolic excursions and giving rise to considerable enlargement of 

 the oro^aa, causes the heart to pump more blood around with each systolic contraction than 

 blood of a high temperature does. In respect to its influence upon the heart, therefore, heat 

 resembles atropine used in -small doses, and cold resembles it as when it is used in large doses.

In this paper the action of the so-called antipyretics on the heart and blood vessels istreated 

 quite exhaustively. The paper itself is but a summary of the results which wore obtained 

 from a large number of experiments, and all that need be said here is that antipyrin was found 

 to be the only real remedy among them.
