90 STONE 1 iN THE II R I N A R V PASSAGES. 



Stone in the bladder mnj' be suspected, wlien tlipre is much feve 

 aeromj);\Mied by a frecnuMit turning of the head, and earnest gaze i,^ 

 the tl, inks; when th<^ hind linihs trenihU', and thi^ro are incirrotu^i 

 endeavours to paf^s urine, or it is evacuated in small quantities, and 

 niiii<2led with hhjod. 



'I'he suspicion may very easily be reduced to certainty, by examin- 

 ing the bladder with the hand introduced into the rectum, or last jjut. 

 The l)l-.ulder of tlie ox, as has already been described, lying so much 

 more in the pelvis than the bladder of the horse does, the stone cannot 

 lail of being felt if there is one. 



The presence of stone in the bladder having been thus proved, tha' 

 faviner will pursue the most judicious course who sends the beast 

 immediately to the butcher; (or no medicine will dissolve it, and t' 

 animal will lose condition ev(>ry day. 



A skilful veterinarian is able, indeed, to remove the stone by ne 

 operation of lithotomy: but he must well understand theanatonr> o' 

 cattle; and, after all, the operation would be attended with son.e 

 danoer and considerable expense. 



The retention of a small calculus in some part of the urethra occurs 

 much oftener than is generally suspected. The symptoms would be 

 nearly the same as those of stone in the bladder, except that the stop- 

 page of urine would he more complete. On examination, the stone 

 \\ ill be easily felt, and generally in the double curvature of the penis 

 An incision may be made upon it, and it may be thus easily extracted. 

 Two or three s\iiures, according to the size of the calculus, having 

 been passed through the edges of the wound, it will usually heal in 

 a few days.

DISEASES OF THE EYE. 



Oxen are very apt to receive injuries about the eye, as wounds 

 penetrating into the orbit of the eye, or even fractures of the orbit. 

 The principal thing is to prevent or abate inflammation, by fomenta- 

 tii ns or poultices, and a little physic, and to leave nature pretty 

 nearly to herself. Either from injury, or from a disposition in the 

 bullock to throw out tumours of every kind, there are frequently bony 

 enlargements about the eyes of Dxen. It will be easily seen how far 

 they are a nuisance to the animal, or impede the sioht; and if it is 

 necessary to remove them, the aid of a professed practitioner on cat- 

 tle should be obtained, as an important vessel may be divided, or a 

 sad blemish left. 



Soft fungous tumours sometimes grow out of the orbit, or from the 

 bonis around, 'i'hese can only be got rid of by the use of the knife, 

 und iliat -iho'ild be placed in a skilful hand : but even in the most
