It has been said "that foals and yearlings suffer more from parasites in the paddocks, than they do on adjoining farms where only a few animals are ;' "This is explained," says Dr. Cobbold, "by the relatively greater amount of Qgg dispersion proceeding from the infected brood mares. It is quite evident that the lives of many valuable animals arc annually sacrificed by the neglect of hygienic arrangements. The palisade A\orm, as this parasite is commonly called, is chiefly destructive to young animals, and, as Mr. Percivall has remarked, is commonly the cause of lingering and hidden disease terminating in death, without any suspicion on the part of the practitioner as to the nature of the ;' Treatment for these worms fs not of much value. We have lastly to speak of the common hydatid of the horse. It is well known that after death hydatids (Echinococci vctci'iHonnn) are sometimes found in the various organs and glands of the horse, more especially in the lungs, liver, and kidneys, and sometimes in the brain.
