Rest and a cooling diet are the best remedies 

 for this apparent affliction. Should tenderness of 

 the kidneys be evinced upon the touch, or other 

 symptoms of augmented pain appear, give the Tonic 

 Ball, No. 2, page 201, occasionally employing 

 No. 1 instead : the alternation will be found bene- 

 ficial. If these symptoms increase, (which we 

 should not apprehend), then, of course, the attack 

 must be met with strong appropriate remedies. 

 But we have never known one case of bloody urine 

 out of several score, wherein the appearance thereof 

 having ceased with the day of rest, but comes on 

 again with hard labour, that did ever terminate in 

 genuine inflammation of the kidneys : it will return 

 at intervals (upon hard work) during the animal's 

 whole life, probably, without any further ailment at-

 their way even into the blood, our astonishment 

 ought to cease at discovering earthy particles, often 

 hardened into stone, in some one or other of those 

 parts.
