Dr Duckworth, Report on the brain of a 
length measured from the frontal pole to the occipital extremity. 
The following notes were made. 
The first section (Fig. 8) passed just in front of the genu of 
the corpus callosum, and of the extreme tip of the temporal lobe. 
The sectional area is abnormally small. The lateral ventricle is 
not opened. The nucleus lenticularis is seen. The cortical grey 
matter varies in depth from 2 mm. to 1*4 mm., the thinner cortex 
being found on the orbital surface of the frontal lobe. Besides 
the small sectional extent and the attenuation of the cortical 
layer of grey matter, no abnormal appearances (such as heterotopia) 
are observed. 
Figs. 8, 9, 10 ( x £). The anterior surfaces of coronal sections of the right 
hemisphere. Fig. 8. The section passed just in front of the temporal pole. 
Fig. 9. The section is through the mid-point of the length of the brain 
measured from the frontal to the occipital pole. Fig. 10. Section at three- 
quarters of the distance between the frontal and occipital poles. 
The second section (Fig. 9) divided the hemisphere into anterior 
and posterior halves. The total sectional area is abnormally 
small. The anterior end of the descending cornu of the lateral 
ventricle is seen to be widely distended and it contains coagulated 
blood. Beneath this region the cortex is microgyrous. The 
cortical grey matter is thicker than in the preceding section 
and attains a depth of 3 - 7 mm. in the superior frontal gyrus. 
The grey matter of the optic thalamus, nucleus caudatus and 
nucleus lenticularis is quite distinct and these masses present 
the normal relations to each other and to the corpus callosum 
(here cut across transversely), except that the uppermost part 
of the lateral ventricle being dilated forms a space between the 
corpus callosum and the nucleus caudatus together with the optic 
thalamus. Further details could not be recorded owing to the 
imperfection of the central part of the section. 
The third section (Fig. 10) passes immediately in front of the 
depressed area of the cortex of the occipital lobe, and behind
