FISSURES OF THE TEMPORAL LOBE (LATERO-VENTRAL SURFACE).—The super- 
temporal fissure sweeps caudad in bold curves, until, near the region of 
the marginal gyre, it bifureates, its dorsal limb joining the intermedial, 
the ventral limb passing on to join a meditemporal segment. Thus the 
course of fissural confluence may be followed from the tip of the tem- 
poral lobe as far as the exoccipital, and dorsad, by means of the inter- 
medial and parietal to the postcentral. 
There are at least three distinct meditemporal segments, the caudal 
one anastomosing with the exoccipital, supertemporal and the subtem- 
poral. 
The subtemporal is of good length (10 em.) anastomosing caudad with 
the meditemporal, where the fissure sweeps well upon the lateral aspect 
of the lobe. 
The collateral attains a length of 13.3 cm. and presents many flexuosi- 
ties. In its caudal part it is particularly ramified. Cephalad it anasto- 
moses with the postrhinal (amygdaline) fissure. 
GYRES OF THE TEMPORAL LOBE (LATERO-VENTRAL SURFACE).—The super- 
temporal gyre is broad in its caudal portion, narrow cephalad. The medi- 
temporal and subtemporal are of gocd width, and each is fairly well de- 
mareated. The subcollateral and subealearine gyres are very wide in 
their caudal portions, and grow narrower toward the temporal tip. The 
subealearine is notable for its rich fissuration. 
The transtemporal fissures and gyres present nothing unusual. 
InsuLa.—The insula seems a trifle better developed—so far as fissuration 
is concerned—than that on the left side, but it is on the whole less mass- 
ive. There is the usual long postinsular gyre, and five preinsular gyres. 
2. Brain oF “ NoOKTAH.” 
(See Figures 7 to 12.) 
The second specimen is that of an adult male, “ Nooktah,” husband 
of “ Atana.” His age is likewise in the neighborhood of fifty-five years. 
“Nooktah” died on May 14, 1898. The brain was removed on May 
16, and weighed, while fresh, 1470 grammes. It was placed in a mix- 
ture of formal and alcohol. Its weight on May 25, 1901, was as follows: 
Left hemicerebrum (plus a piece of callosum belonging to the right 
half), 474 grammes; right hemicerebrum, 470 grammes; cerebellum, pons 
and oblongata, 142 grammes; total 1086 grammes. 
The loss in weight during a period of over three years amounts to 
384 grammes, or 26 per cent of the original weight. 
THE CEREBRUM. 
The cerebrum is well preserved and quite firm, so that it is difficult 
to study in detail the depths of the fissures. In general, the fissura- 
tion is fully equal in complexity to that exhibited by “ Kishu’s” cere-
