were retained in the jaw: the right lateral lower incisor, the four 
canines, and the eight molars. 
“The permanent teeth (bicuspides) destined to succeed these 
had their crowns about half formed. Those of the large permanent 
canines were in the state of hollow cones, supported, like the fore- 
going, by large and highly vascular matrices, in the course of con- 
version into the dental substance. The crowns and fangs of the 
lateral permanent incisors were almost completed. ‘There was no 
trace of the matrix of the last true molar tooth in the lower jaw. 
«« The membranes of the brain were unusually injected, and there 
was much serum between the arachnoid and pia mater. An unusual 
quantity of serum had likewise been effused into the cavities of the 
thorax, pericardium and abdomen. 
«The principal and lethal morbid changes were found in the chest : 
the right lung adhered by nearly the whole of its superficies to the 
surrounding parietes. Its substance was disorganized throughout 
by numerous tubercles, some of which had begun to soften in the 
centre. The left lung had been the seat of more recent and active 
inflammation ; its cellular tissue was gorged with bloody serum, and 
its lower part hepatized. A small cyst, with firm parietes and clear 
fluid contents, adhered to its surface. The heart had an oval patch, 
two-thirds of an inch broad, of opake lymph upon its surface, as in 
a former Orang: a cyst like that on the left lung adhered to its 
surface. The mucous membrane of the trachea and bronchi was of 
a rose-tint, and the tubes loaded with frothy opake mucus. 
«The right lobe of the liver was enlarged and congested; there 
was a slight adhesion of the epiploon to the spleen, which organ pre- 
sented a slight anomaly sometimes observed in Man, viz. a small 
separate supplemental spleen, about half an inch in diameter, attached 
to the epiploon, just below the spleen proper. With the exception 
of a slight increase of vascularity at one or two parts, the whoie ali- 
mentary tract was in a sound state. 
«“The laryngeal sacs were expanded as far as the clavicles and 
shoulder-joint, but did not extend below the clavicles. 
«The ovaria were of a narrow elongated form, with a slightly 
tuberculated surface. I obtained ova from several of the graafian 
vesicles, and one of these contained two ova: they closely resemble 
those of the human subject, have a thick transparent vitelline tunic, 
containing the minutely granular contents and germinal vesicle : dia- 
meter 345th of an inch.” 
Prof. Owen exhibited one of these ova, and concluded by obser- 
vations on the brain of the Oran-utan. Its weight was 11 oz. 2 drs. 
12 grs. avoird., including the injected pia mater.
