DESCRIPTION OF THE SHIPPEA MAN BY PROF. A. MACALISTER.

"The calvaria is large, dark coloured and much broken. The base, facial

bones and part of the left brow ridge and glabella are gone. The

sutures are coarsely toothed and visible superficially although

ankylosis has set in in the inner face. The bone is fairly thick (8·10

mm.), and on the inner face the pacchionian pits are large and deep on

each side of the middle line especially in the bregmatic part of the

frontal and the post-bregmatic part of the parietals. The superior

longitudinal groove is deep but narrow, and, as far as the broken

condition allows definite tracing, the cerebral convolution impressions

are of the typical pattern.

[Illustration: Fig. 7.]

"The striking feature is the prominent brow ridge due to the large

frontal sinus. The glabella was probably prominent and the margins on

each side are large and rough and extend outwards to the supraorbital

notches. The outer part of the supraorbital margin and the processus

jugalis are thick, coarse and prominent (Fig. 7).

"In norma verticalis the skull is ovoid-pentagonoid euryme-topic with

conspicuous rounded parietal eminences, slight flattening at the

obelion and a convex planum interparietale below it (Fig. 8).

[Illustration: Fig. 8.]

"In norma lateralis the brow ridges are conspicuous; above them is the

sulcus transversus from which the frontal ascends with a fairly uniform

curve to the bregma. The frontal sagittal arc above the ophryon

measures 112 mm. and its chord 116. Behind the bregma the parietals

along the front half of the sagittal suture have a fairly flat outline

to the medio-parietal region, behind which the flattened obelion is

continued downwards with a uniform slope to the middle of the planum

interparietale whence it probably descended by a much steeper curve to

the inion, which is lost. The parietal sagittal arc, including the

region where there was probably a supra-lambdoid ossicle, was about 140

mm. and its chord 121 but the curve is not uniform.

"In norma occipitalis the sagittal suture appears at the summit of a

ridge whose parietal sides slope outwards forming with each other an

angle of 138°, as far as the parietal eminences. From these the sides

drop vertically down to the large mastoid processes. The intermastoid

width at the tips of the processes is 115, but at the supramastoid

crest is 148 (Fig. 9).

[Illustration: Fig. 9.]

"In norma frontalis the conspicuous feature is the brow ridge. This

gives a kind of superficial suggestion of a Neanderthaloid shape, but

the broad and well arched frontal dispels the illusory likeness. The

jugal processes jut out giving a biorbital breadth of 115 mm. while the

least frontal width is 97 and the bistephanic expands to 125. There is

a slight median ridge on the frontal ascending from the ophryon, at

first narrow but expanding at the bregma to 50 mm. The surface of this

elevated area is a little smoother than that of the bone on each side

of it.

"The other long bones are mostly broken at their extremities. The

femora are strong and platymeric. The postero-lateral rounded edge,

which bears on its hinder face the insertion of the gluteus maximus,

taken in connexion with the projection of the thin medial margin of the

shaft below the tuberculum colli inferior causes the upper end of the

shaft to appear flattened. The index of platymeria is ·55. The femoral

length cannot have been less than 471 mm. The man was probably of

middle stature, not a giant as was the Gristhorpe man. The tibiæ are

also broken at their ends, they are eurycnemic (index ·80) with sharp

sinuous shin and flat back, the length may have been between 335 and

340 mm. The humeri are also bones with strong muscular crests, and the

ulnæ are smooth and long. The fibula was channelled. There is nothing

in the bone-features which is inconsistent with the reference of the

skull to the Brachycephalic Bronze Age race.

"In the following Table are recorded the measurements of the different

regions. The two crania which I have selected to compare with it are

(1) a Round-barrow skull from near Stonehenge (No. 179 in our

Collection) and (2) the Gristhorpe skull, to both of which it bears a

very strong family likeness.

"The resemblance to the two Round-barrow skulls of the Bronze Age is

too great to be accidental, so we may regard this as a representative

of that race, possibly at an earlier stage than the typical form of

which the two selected specimens are examples (Fig. 10).

"The mandible also resembles that of the Gristhorpe skull in general

shape of angle and prominence of chin.
