projection in the middle of the upper lip was absent. The ears 
were also well formed. The forehead was somewhat high and 
narrow, and sloped somewhat rapidly backwards. When looked 
at from the side the head appeared unduly elevated in the frontal 
region, while the part of the occiput which lay immediately behind 
the lambdoidal suture was inclined almost at a right angle to the 
posterior or vertical part of the bone. 
On removing the scalp the anterior fontanelle was found to be 
almost entirely closed, while there was a narrow oval gap between 
the posterior halves of the two parietal bones which was closed by 
membrane. The dura mater was of normal thickness at the vertex, 
but the falx cerebri was somewhat defective, presenting less than 
half the normal depth of that structure. The tentorium cerehelli., 
especially in the part ivhich projects in the middle line above the 
vermiform lobe of the cerebellum, was considerably thickened, and 
was somewhat difficult to detach from the brain. 
The cerebrum was found imperfectly divided into two hemi- 
spheres (fig. 3), while the cerebellum, pons, and medulla presented 
an almost normal appearance, the only abnormality in the latter 
being the nearly complete absence of the anterior pyramids, so 
that the two olivary bodies almost met in the middle line (fig. 2). 
Similarly the pons seemed smaller than usual. The cerebellum 
was completely uncovered by the cerebrum (figs. 3, 4). The two 
corpora quadrigemina could be seen in the small gap between the 
cerebrum and cerebellum. The cerebrum had the shape represented 
in figs. 2, 3. When seen from above it somewhat resembled that 
of a pigeon. The great longitudinal fissure was very shallow, being 
about a quarter of an inch deep at its posterior part. Two extremely 
shallow sulci ran from before backwards (as shown in fig. 3) 
almost parallel to the great longitudinal fissure. When seen from 
below the cerebral hemispheres were folded posteriorly over the 
corpora quadrigemina somewhat as a mushroom is over its stalk 
(fig. 2). They had a rounded edge and an undermined surface. 
Between the pons and the cerebrum was a large globular mass 
imperfectly divided into two lateral halves by a shallow groove 
extending forwards from the upper margin of the pons. There 
were no crura cerebri, and no distinct interpeduncular space. 
Above the globular mass was a small spherical projection whiclp
