The tubes of the cortex are complete, though the lumen of the tubes is often 
closed. Under a high power the individual cells are not recognisable (Plate X. Fig. 3). 
The whole tube forms strands staining faintly with haemntoxylin. The connective tissue 
between the tubuli contorti is often very prominent, standing out in .sliarp contrast to 
the faintly staining and sometimes yellow-coloured epithelium cells (Plate IV. Fig. 4). 
In other cases, the epithelium layer is conspicuous and the connective tissue 
almost invisible. If such sections be floated through alcohol into water, the currents set 
up wash out the epithelium cells and the connective tissue becomes apparent (Plate IV. 
Fig. 5). The reason why the connective tissue is hidden until the epithelium cells have 
been washed out is that both, having lost their specific chemical properties, stain 
almost exactly alike. 
The large and mediumsize bloodvessels persist and in some cases they can be 
recognised by their general charateristics only ; the details of their microscopical struc- 
ture have disappeared (Plate VII. Fig. 1). The arteries, but not the veins, are contracted, 
and their coats are converted into homogeneous tissue, showing no differentiation. In 
other kidneys, however, the bloodvessels are almost perfect, even as regards the details 
of their histological structure. 
I have already pointed out in another paper (Remarks on the histology and patho- 
logical anatomy of Egyptian Mummies, Cairo Scientific Journal n°40 volume 4; January 
1910) how often one finds evidence of disease in these organs. 
INTESTINES. 
I have examined two parcels of intestines given me by the authorities of the Mummies of 
Medical School in Cairo. The interstices between the intestines were filled with earth XXlstdijnasty. 
and sawdust, and I had great difficulty in removing this foreign matter. In spite of 
every possible care, I never succeeded in unfolding the coils of the intestines, and I 
am still unable to say whether the whole or only part of the intestines was placed in the 
abdomen. I should feel inclined to think, however, that neither of these parcels cont- 
ained more than half the length of the intestines. The difficulty was increased by the 
fact that a large part of the guts in one case had been transformed into that peculiar 
substance for which I have provisionally used the name of adipocere. 
Prof. Elliot Smith kindly gave me some small pieces of intestine. In Cairo these 
fragments were hard, dry and brittle, but after being kept a few weeks in the moist 
heat of my laboratory at Alexandria during the summer, they became somewhat softer, 
more pliable, and gave off a distinctly musty odour.
