nation of one of these, with four other lambs which had been at the 

 Station for the five previous uiontlis, revealed numbers of IStrongylus 

 contortus in all stages of growth, and o( Dochmius cernuus^ Trichoceph- 

 ahis affinis and Twnia expaiisa. These Uimbs were sui)i)lied with well wa- 

 ter, and were allowed to run in a small, dry, grassy yard connected with 

 a stable. The presence of these species of all sizes in the former group 

 of lambs showed that they acquired them on the place, and that their 

 development was direct; that is, they did not pass through a secondary 

 host in passing between the sheep and thelambs, for all of the conditions 

 were under inspection. The grass in the yard became very short, and 

 probably it was because the sheep ate it so close to i he ground that they 

 became more infested with worms than sheep ordinarily do. The his- 

 tory, therefore, is probably as follows : The eggs fall to the ground ; 

 they are eaten by other sheep along with their feed, and they then ar- 

 rive at the stomach and develop there. 



The disease they cause can not easily be distinguished from that pro- 

 duced by other intestinal parasites. In the worst cases, besides a gen- 

 eral lack of tone and good health, there is weakness, paleness, some 

 fever, diarrhea, etc. In fatal cases death is said to occur within a very, 

 few days after the illness is observed; but, as the parasites develop 

 slowly, it is probable that no symptoms of illness are apparent until 

 after the lambs have been ailing for some time. A positive diaguobis 

 is to be made ouly by 'd, post-mortem examination. The little worms, if 

 present in large numbers, will api)ear like masses of threads lying in 

 the stomach. If the shee[) has beeu killed for examination, the worms 

 will be seen wriggling and squirming m all directions. 



Treatment. — Various remedies are proposed, but of those available 

 an emulsion of milk and turpentine, prepared by shaking the mass well, 

 seems most practicable. Add 1 part of spirits of turpentine to IC parts 

 of milk, and give from 2 to 4 ounces of it to each aniuial, according to age 

 of patient. One dose should be sufticient ; if not, repeat it in three or 

 four days. Or, take of linseed oil, 1 ounce; turpentine, one-half ounce, 

 shake well and give as one dose. Quantities sufficient for any number 

 of sheep may be made up in these proportions. 



The foUowiug recipe is from Finlay Dun's Veterinary Medicine: 

 Common salt, 3 pounds ; powdered ginger and niter, half a pound each ; 

 dissolved in 3 gallons of warm water ; add 24 ounces of turpentine 

 Avhen nearly cold. The dose for iambs between four and six months' 

 old is 2 ounces. The entirequantity is sufficient for one hundred and sixty 

 lambs. For delicate Iambs, which are coughing and purging, the same 

 writer recoiumends oil of turpentine, powdered gentian, and laudanum, 

 2 ounces each, all to be dissolved and stirred in 1 quart of linseed tea 

 or lime water. This quantity is sufficient for ten or twelve doses. 



Ziiru recommends (after Rabe) the picrate of potash, because it is 

 less irritating to the patients. The dose for. a laiub is from 2i to 5 

 grains; for an adult up to 20 grains. It cau be given dissolved ill; 

 water.
