small scars of a keloid character. The papillomatous growth over 
the toes varies from 3 to 9 mm. in thickness. 
The shading of the growth is most striking. It resembles, both 
in appearance and colour, the old dry moss found growing on rocks 
which are exposed to very little moisture, the colour varying from 
yellow to slate grey. 
On the left leg (Plate VIII, fig. 1) are two patches, measuring 
1-3 by 17 cm. and r8 by 27 cm. They are indurated, warty growths 
which are beginning to ulcerate. On the lower third of the leg a large 
ulcer, 4’3 by 4'0 cm. is seen. The induration of the sides is extensive, 
and the centre of the ulcer is slightly excavated. All three ulcers are 
covered with a thin watery discharge, containing pus cells, granular 
debris, numerous staphylococcus aureus and citreus, also many bacilli 
of varying sizes, negative and positive to Gram. 
The patient states that these three ulcers had originated as small 
nodular growths, resembling the one on the right leg just below the 
knee, and that traumatism caused these nodules to swell. Then litt e 
vesicles appeared and an ulcer resulted. He believes that the nodules 
appeared some three months before his visit to the hospital. 
Some of the verrucoid growths over the toes were burnt with the 
thermo-cautery before being excised. A small portion, with aseptic 
precautions, was inserted under the skin of the nose of a rabbity 
The incision was closed with collodion. The wound healed, and 
six weeks later a small vesicular eruption appeared The vesicle 
burst and clear watery fluid exuded. From the middle of the clu , 
minute hard nodules developed. The tissue around the base of 
nodules gradually became more infiltrated. Ten days la er 
nodules commenced to resemble minute warts, which weregently 
itchy, as the rabbit was continually scratching t e spo 
them to bleed. The papillae became encrusted withfried mmdate 
the patch measuring r 3 by n o cm. above the surface of the ^ Tte 
hind paws became infected from the scratching, and final y 
warty condition was noted on the ears. ^—nhles the
