 salis. 



Fish. Bee-hive, 88. John Hunter.

ter in which they live. Air, 55 .4. 



Two carps, 53 '042 * Oyster, 82 on the sea- shore Cey- 



Two tenches, . 52'772f Ion. 



Water in which these fish Leech, same as that of the me- 



lived, . 51-494J dium. 



Within these few years very delicate experiments have been 

 made by Becquerel, Breschet, &c. upon the temperature of dif- 

 ferent internal parts of the body by means of thermo-electricity. 

 Two wires of different metals are soldered together and con- 

 nected with a magneto-electric multiplier. The extremities of 

 these wires are plunged into the part of the body whose tempe- 

 rature is wanted, the deviation of the needle marked, and water 

 heated till it produce the same deviation. It is obvious that the 

 internal part of the body experimented upon has in this case the 

 same temperature as that of the water. The following tables 

 exhibit the result of a set of experiments made by MM, Becque- 

 rel and Breschet upon three individuals distinguished by the let- 

 ters A, B, and C. A and B were 20 years of age each, while C 

 was 25. ||
