Further, meclninical trac-tors do not allow us to take cognizance of rotation movements. For thesereasons, chiefly, we are in favor of relegating mechanical tractors to thearmamentarium of the veterinary surgeon, never forgetting that the livesei^trusted to our care are far more valuable than those of the cow and hercalf, with both of whom we may, if we please, in full conscience, experi-ment with any curious contrivance.
