G. GENERAL NATURAL HISTORY AND ZOOLOGY. 273 



With an external temperature of 97 to 104, the temperature 

 of the animal rises rapidly to 112 or 113; the phenomena 

 already referred to are more decided, the pupil of the eye is 

 dilated, the muscles are relaxed, and death intervenes in a 

 very short time. 



On removing the animal in season, and exposing it to the 

 ordinary heat of the apartment, its temperature falls to 97 or 

 below, and remains low for several days. When it has come 

 back to its average temperature, however, the experiment 

 may be repeated upon the animal, which will be found to re- 

 sist these agencies much better than before. It is true that 

 it loses much water, but in dry air, as well as in that satura- 

 ted with moisture, the animal becomes heated much less than 

 when first exposed to the action of a high temperature. At 

 the same time, however, it shows signs of indisposition, loses 

 its appetite, and becomes sluggish, producing less caloric than 

 in a state of health. 8 J5, December 21, 1872,592. 



INOCULATING HEALTHY ANIMALS ^VITH TUBERCULOUS MATTER. 



From a series of experiments by Chauveau upon the possi- 

 bility of transmitting pulmonary diseases to healthy animals, 

 he concludes that with cows, lambs, horses, etc., the only 

 thing that will reproduce tuberculosis is the granulation, or 

 the cheesy tuberculous substance from the human being af- 

 fected with phthisis. The other products of lung decompo- 

 sition only develop a transitory inflammation of the spot af- 

 fected ; but when the tuberculous products themselves are 

 introduced, the point of contact soon exhibits an inflamed 

 tissue, and still later there is a generalization of the tubercu- 

 lous modules in the lungs and in other organs. 8 -S, March

"sea-serpent" in the bay of PANAMA. 



The Panama Star and Herald of February 16 contains an 

 account of a marine animal, resembling in many respects the 

 celebrated "sea-serpent" of the Northern Atlantic, which was 

 seen from the deck of the steamer Guayaquil a few days be- 

 fore, when off" the Pearl Islands, in the Bay of Panama. Its 

 head was like that of a sea-horse {Hippocampus)^ and its 

 length, estimated from the undulations of its body as they 

 appeared above the water, was about twenty-five feet. A
