An interesting instance of this uncommon disease is described in the "Veterinary Record," Vol. III., page 148. The dog was a French poodle, three months old. He was found lying on his side, making unsuccessful efforts to get on his feet, and in his attempts striking his head against the ground. When placed on his legs he ran about with his head down, his legs crossed, and his gait unsteady until he dropped down. These symptoms were ascertained to have existed since birth, and they had gradually increased in severity. Three other puppies of the same mother were affected in the same way, but in a less severe degree. The dog ground his teeth, and had a voracious appetite. Subsequently he became worse, but the senses of smell, sight, hearing, and feeling were not affected. No unusual heat of head, nor enlargement, nor yielding of the bones on pressure, could be detected; but the pulse was slow, the bowels costive, the head drooped, and the eyes rolled upwards when the head was raised.

The symptoms and history indicated a con-genital inherited disease, affecting the cerebellum more than the cerebrum.

The description of the post-mortem appearances is highly unsatisfactory. There were in the "cranial cavity" about two ounces of straw-coloured serum, "general inflammation of the meninges of the brain, and a peculiar state of the inner surface of the brain" - whatever this "peculiar state" may mean. A more careful and minute account of what was seen would have given additional value to a case of great pathological interest.
