Inhydrocephalics who attain adult life the skull may becomecompletely covered in with bone. The brain presents great changes. The lateral ventriclesare widely distended, and the crura cerebri, corpora striata, EYDBOGEPHAL US 631 optic tlialami, and other structures in the base of the brainare flattened. The cerebral hemispheres form thin boundariesto the ventricles, often less than 10 mm. in thickness; theconvokitions become obhterated. In nearly all the speci-mens the distension is limited to the lateral and third ven-tricles ; occasionally the fourth ventricle also is distended(Fig. 333). In some specimens each lateral ventricle has been.

When the ventricles are very distended and the skullis proportionally thin, a wave of fluctuation may be trans-mitted from side to side. In exceptional cases the head istranslucent. In an account of hydrocephalus it is difficult to avoidreference to the classical case of James Cardinal, especially asa cast of his head is to be found in many pathologicalmuseums (Fig. 334). James Cardinal died at the age of 29 years in Guys 632 P8EUD0-CY8T8 Hospital, under the care of Sir Astley Cooper, in 1824. Hewas born at Coggeshall, Essex, in 1795. At birth his headwas very little larger than natural. A fortnight later itbegan to increase, and gradually grew until he was five yearsold, and then appeared to remain stat
