prevails. Cold icings and other fixings are called into requisi- 

 tion to smother the fire of thirst which rages within. Every body 

 partakes freely — the young and the aged, the exhausted and vigor- 

 ous, the laborer wearied by a hard day's work, and the rich man 

 of no work — each and all are doing their best to see the bottom 

 of the pitcher, and to pitch their bodies into the watery element. 

 Yet, after all, how few persons complain of any bad effect from it 



Inquire into the history of some of the acute maladies that are 

 supposed to arise from water-drinking, and it will be found thai

 abraded part should be lubricated two or three times daily with 

 common tar and olive oil, equal parts, and this will soon restore 

 the parts to soundness. Should there be no abrasion, yet tume- 

 faction, heat, and tenderness, a cold-water pledget, renewed as 

 occasion seems to require, will improve the condition of the parts, 

 when recourse must be had to the tar and oil lotion. Sometimes, 

 in consequence of neglect, the integument becomes callous or indu-

 The treatment for this consists in smearing the callous with the
