Meteorological Observations. 71 



Impregnation is accomplished through the medium of water, and 

 not by actual contact. The growth and development of the triton 

 are materially influenced by temperature, and but little by the action 

 of light. The triton possesses the power of reproducing its lost 

 limbs, provided the temperature be within the limits of 58° and 75° 

 Fahrenheit; but at lower temperatures, and during the winter, it 

 has no such power.
