the middle of the basis of the heart, had the blood flowing 

 from these vessels of 106, 106-J-, and 107°; the atmospheric 

 temperature being at 31". 



An ox, killed in a similar manner, the blood 103"; at- 

 mosphere 50°. 



Three sheep, killed by dividing the carotid arteries, and 

 internal jugular veins : their blood 105, 105, 105i°; atmo- 

 sphere 41°. 



Three frogs, kept for many days in an equable atmo- 

 sphere at 54° ; their stomachs 62°. 



The uatery fluid issuing from a person tapped for dropsy 

 of the bellv ior^; the atmosphere being 43°, and the tem- 

 perature of the superficies of the body at 96°. 



These temperatures are considerably higher than the com-' 

 mon estimation. 



A man's arm being introduced within a glass cylinder, it 

 was duly closed at the end which embraced the head of the 

 humerus ; the vessel being inverted, water at 97° was poured 

 in, so as to fill it. A ground brass plate closed the lower 

 aperture, and a barometer tube communicated with the 

 water at the bottom of the cylinder. This apparatus, in- 

 cluding the arm, was again inverted, so that the barometer 

 tube became a gage, and no air was suffered to remain in 

 the apparatus. On the slightest action with the muscles of 

 the hand, or fore-arm, the water ascended rapidly in the 

 gage, making librations of six and eight inches length m 

 the barometer tube on each contraction and relaxation of 

 the muscles. 



The remarkable effects of crimping fish by immersion in 

 water, after the usual signs of life have disappeared, are 

 worthy of attention ; and whenever the rigid contractions 

 of death have not taken place, this process may be prac- 

 tised with success. The sea fish destined for crimping are 

 usually struck on the head when caught, which, it is said, 

 protracts the term of this capability; and the muscles 

 which retain this property longest are those about the 

 head. Manv transverse sections of the muscles beinar 

 made, and the fish immersed in cold water, the contrac- 

 tions called crimping take, place in about five minutes; 

 but, if the mass be large, it often requires thirty minutes to 

 complete the process. 



Two flounders, erxh weighing I926 grains, the one being 

 in a Slate for crimping, the other dead and rigid, were put 

 into water at 48", each being equally scored with a knife. 

 After half an hour the crimped fish had gained in weight 



53 grains^
