Handling. The indications in hydrocephalus are the destruc-tion of the tumor by opening the sac and permitting the liquidto escape and then diminishing the size of the osseous portionby dividing the bone with the obstetric chisel. The incisioninto the tumor is easily made with the scalpel or ring knife, andthe cranial bones are so thin and weak that they are easilybroken down by means of the chisel, as described on page one case, in the mare, where the anterior limbs had not yetadvanced into the canal, we opened the sac and allowed its con-.

Calf, (.?\fter photograph). tents to escape, broke down the bones, drew the head throughthe birth canal and amputated it, after which we repelled theneck, secured the two anterior limbs and extracted the headlessfetus. When the fetus presents posteriorly, and hydrocephalus hasbeen diagnosed, the handling is analogous to that for the an-terior presentation. As a general rule, it is not essential to decrease the size of thehead very greatly, or, in some cases, to decrease it at all by arti-ficial means. Fig. 124 represents a hydrocephahc calf, whichwas expelled without aid, the head-sac of which had a capacityof about 5 gallons. We had been called because of the dys-tokia, but, pending our arrival, the calf had been examination, it appeared that the expulsive efforts hadcompressed the sac to such a degree that it ruptured through the Ascites of the Fehis 739 crib
