Plaintiff was was the owner of a certain roan mare of the value of $200; that, on or about the 21st day of April, 1888, the said mare became and was sick with some disease then unknown to plaintiff in kind and character; that, at said date last aforesaid, and long prior thereto, the defendant claimed to be, and advertised and held himself out to the public to be, a veterinary surgeon, and asked to be employed as such in the treatment of sick and diseased horses. The court held that a veterinary surgeon, in the absence of a special contract, engages to use such reasonable skill, diligence, and attention as may be ordinarily expected of persons in that profession. He does not undertake to use the highest degree of skill, nor an extraordinary amount of diligence. In other words, the care and diligence required are such as a careful and trustworthy man would be expected to exercise. The case was remanded for determination of further proofs.
