 water rapidly evaporated, leaving all its salts 

 behind, and rendering the remaining water much 

 too dense. In the correction of this evil the fresh 

 water was added too rapidly, and inflicted on 

 the nervous system of my poor crass a shock 

 from which it never recovered.

 ingly small. Whenever the creature is in this 

 state it is not easily restored to health and
