272 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



haled from the kings. Making proper allowance for the 

 head, in addition, the entire quantity may be reckoned at 

 about 60 grains per diem. During the same time, however, 

 the quantity thrown out by the lungs amounted to 13,500 

 grains ; so that the percentage exhaled by the skin is very 

 trifling. The quantity of acid eliminated increased with the 

 increase of the temperature to which the subject was ex- 

 posed. 13 A^ January 1, 1873, 12. 



RESULT OF SUPPEESSING EXCEETIONS OP THE SKIN^. 



Experiments have been tried by Socoloft" as to the effect 

 of suppressing the excretions of the skin, by shaving rabbits 

 and painting the skin over with some material impervious to 

 the passage of vapor. It was found that this always, sooner 

 or later, produced fatal results, the animals a few hours before 

 death exhibiting intermittent cramps and convulsions, while 

 the temperature in the rectum fell to a considerable extent. 

 Even wrapping the animal in cotton failed to produce any 

 material increase of the temperature of the intestines or to 

 delay death. The inhalation of oxygen was equally power- 

 less in preserving life. Ulcers, arising from deep-seated ex- 

 travasations, were found in the stomach. Albumen made 

 its appearance in the urine shortly after the animal had been 

 varnished. Whatever the substance used for coating the 

 animal, whether simply a gelatine, gum, or regular varnish, 

 inflammation of the kidneys was the result, sometimes ac- 

 companied by enlargement of the cell elements, and some- 

 times by their fatty degeneration. 13 A^ March 1, 1873, 93. 



EFFECT OF HEAT ON THE TEMPEKATURE OF ANIMALS. 



An investigation of the effect of a high temperature upon 

 animals has lately been published by Professor Rosenthal, of 

 Erlangen. As the result, he found that if rabbits be intro- 

 duced into inclosures the atmosphere of which is 52 to 90 

 Fahr., the temperature of the animal under treatment does 

 not vary, excepting for some slight transitory oscillations 

 between 79 and 90. From 90 to 97, the temperature of 

 the animal rises to 106 or 107, and then is stationary; the 

 animal becomes prostrated, and pants for breath, with its 

 limbs stretched out and wide-spread, the pulsations of the 

 heart very frequent, and the cutaneous vessels much dilated.
