THE NEANDERTHAL SKULL 583 
put greatly inclined, none (except perhaps one of the Borreby skulls) 
has been shown to exhibit that peculiarity in so marked a degree as it 
does. 
Professor Schaafhausen continues :— 
“Lastly, Mr. Huxley's remark, that the two lateral sinuses, that Is 
to say, the inferior limits of the posterior cerebral lobes are perfectly 
visible, is quite as erroneous : this observation is based on photographs : 
but in the specimen there exists only the commencement of the right 
sinus, where it takes its origin from the superior longitudinal sinus.” 
I greatly regret to differ from so competent an anatomist, who has 
further had the advantage from which I have been debarred, of ex- 
amining the original specimen: but, after a re-examination of the 
photographs, and a careful study of the cast of the interior of the skull, 
which Dr. Fihlrott has been good enough to send me, I must stand 
by my original view, that the inferior limits of the posterior lobes of 
the brain are accurately deducible from the markings in the interior of 
the skull. 
Professor Schaafhausen states that there exists* only the commence- 
ment of the right sinus where it takes its origin from the superior 
longitudinal sinus.” On the contrary, both cast and photograph plainly 
show, not merely the commencement of the right lateral sinus, but fully 
an inch and a half of it, passing not only downwards but outwards. 
The outer end of this segment of the lateral sinus certainly indicates 
the line of attachment of the tentorium; which again denotes the 
boundary of the right posterior lobe: and as both lobes are approxi- 
matively of equal extent, I do not think that my statement is other 
than well founded, supposing only the right sinus to exist. 
However, it still appears to me that I can discern clear indications 
of the left, as well as of the right, sinus upon the materials at my dis- 
posal ; and, in any case, the posterior aspect of the cast of the interior 
conclusively shows the lower boundaries of both the right and the left 
posterior lobes. 
Professor Schaafhausen further observes :— 
“Tt is not less singular that Mr. Huxley should have found an 
Australian cranium comparable to that of the Neanderthal. For, ac- 
cording to the opinion of all naturalists (Becker, Martin, Luca, Ecker), 
the cranium of the Australian is narrow, elevated, and declining like a 
roof rapidly from the summit to the temples, whilst that of the Nean- 
derthal is very much flattened, wide behind, and without any trace of 
the conformation indicated.” 
To this I can only reply that, however singular and opposed to 
ordinary opinion it may be, the Australian skulls to which I have
