due to crystals, which have lodged in the barrel of the penis, being 

 transmitted along with the semen at the time of service, interfering 

 with fruitful conception. I have frequently gathered these concretions 

 from the hairs surrounding the sheath of animals which have been fed 

 on the above-named foods. In the ram, the passage and vermifovm 

 process or worm, on the end of the penis is often entirely blocked 

 with these concretions. When thus affected, the animal suffers 

 great pain, it strains and presses very much, the hind parts swell 

 up, and the urine, if not liberated, gets into the body, producing 

 uraemic poisoning, and causing death. Treatment. — Cutting in at 

 the base of the worm, or removing it entirely, sometimes gives relief; 

 the latter I have done on many occasions, both in the ram and 

 wether, and it in no way affected the former as a stock-getter. 

 When wethers folded on turnips suffer from this complaint, the best 

 preventive is to place over the field branches of the common fir tree — 

 the sheep will eat the bark off them readily, and by its action the 

 formation of the crystals is avoided. 



722. Incontinence of Urine. — This may arise from a common 

 cold — catarrh — attacking and causing irritation of the lining 

 membrane of the urinary organs, or from loss of nervous energy 

 in the bladder alone. Both conditions give rise to a continuous 

 dribble of urine, which must be treated according to the cause. 



723. Paralysis of the Bladder arises from want of nerve power 

 in the organ. It may be the result of local or general paralysis, milk 

 fever, injury, or over-distension with urine. In the last case, the 

 muscles of the body of the bladder become so stretched that they lose 

 their tone, and are unable to contract and assist in expelling the fluid 

 in the usual way. Although the urine is constantly dribbling away, on 

 examination (by the rectum), the bladder is found to be full of water, 

 which must be drawn off with the catheter. If the complaint is 

 simply due to loss of nerve power without other complications, a tonic, 

 such as one drachm each of sulphate of iron, and nux-vomica, should 

 be given daily, along with 'a liberal and nutritious diet ; should it, 

 however, occur as the result of some other disease or injury, special 

 treatment is required.
