(After Leuckart.) also common to osseous cachexia and rachitis. Paralysis of the tongue and of the lower jaw is of greater importance. In exceptional cases, where the cysticerci are very numerous and penetrate the brain, signs of encephalitis, vertigo, and turning sickness (gid, sturdy) may be produced. These signs, however, disappear, and the cysticerci undergo atrophy. Interference with movement may give rise to suspicion when the toes of the fore and hind limbs are dragged along the ground, and thus become worn. This pecu- liarity is due to the presence of cysts in the muscles of the limbs, but it occurs in an al- most identical form in osseous cachexia. One symptom alone is pathognomonic, and it appears only at a very late stage—viz., the presence of cysts under the thin mucous membranes which are accessible to examination, such as those of the tongue and eye. Visual examination then reveals beneath these mucous membranes the presence of little greyish-white, semi-transparent grains the size of a grain of barley, or even larger. Unfortunately, in an animal so diffi- cult to handle as the pig, this visual examination is decidedly troublesome, and is usually replaced by palpa- tion. In many instances the disease does not attract attention during the patient's life, and is only discovered on slaughter in consequence of the lesions by which it is characterised. Diagnosis. As the characteristic lesions of cysticercus disease are to be found in the depths of the muscular and connective tissues, and.
