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 
nf xo 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 ints the history of some of the acute maladics that are 
supposed to arise from water-drinking, and it will be found that 
many of the sufferers have a peculiarity of constitution which ren- 
ders them amenable to the laws of primogenital disease, which, 
although latent under ordinary circumstances, can, by disturbing 
the life forces, through neglect, cruelty, and overwork, be developed 
at almost any time of life. 
Animals should never be allowed to drink pond-water. They 
should either have access to a running stream or a clean water-

GALLED Back. 
Galled back, u. sore back, is usually occasioned by had-fitting 
saddle or harness. If that be the case, the shape of the same must

back which comes in contact with it. ‘This can be done by pad- 
ding the concavities with lamb’s wool, and in chambering the con- 
vexities so tnat there shall be no unequal pressure nor causes for 
irritation. ‘et, after all, it may be more economical to procure a 
new article and a better fit; and this may also be the most humane 
policy. 
Treatment.—So soon as an abrasion is discovered on the back, 
te animal should be excused from duty for a few days. The 
abraded part should be lubricated two or three times daily witb 
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. Sometin:es, 
in conseqnence or neglect, the integument becomes callous or irndu- 
rated. This condition was termed by ancient farriers “ sit-fast.” 
The treatment for this consists in smearing the callous with the
