base, containing pns/^ They are distinguishable by being 
more prominent and convex, with a yellow centre, the skin 
being reddened all around. Pressure will cause them to 
discharge their contents, which appear to be degenerated or 
imperfect pus-corpuscles with epithelial scales. 
Vitiligo. 
Epithelial masses of scales held together by a watery exu- 
dation, with a few black or brownish masses. 
Lupus. Lupus exedens {Lupus with phagedenic ulceration) . 
Case 1. — Altered epithelium, serum and pus-corpuscles. 
Fungoid growth, old, and of so dark and marked a cha- 
racter, as to lead to the belief that it must have been an 
accidental deposit of recent date. 
Case 2. — Large epithelial scales, with many highly refract- 
ing irregular granules of fat. 
Case 3. — First examination. — Epithelial scales ; small 
cells ; fat-globules, refracting light, principally egg-shaped ; 
and accidental starch-grains. 
Second examination. — Aggregated mass of epithelial scales, 
held together by some pale yellowish-brown fluid; oil- 
globules, slightly tinged with the yellow discharge ; minute 
ovoid bodies ; fungoid sporules. 
Third examination. — Fatty matter, with a little fibro- 
cellular tissue. 
Case 4. — Submaxillary region. Epithelial scales aggluti- 
nated together by pus- and blood-corpuscles ; the pus recent, 
and showing the characteristic nuclei upon the addition of 
acetic acid. Also fat- and nest- cells. 
Case 5.— Epithelium large and misshapen, apparently 
covered with fungoid filaments ; fat-corpuscles in con- 
siderable quantities, and granular matter. 
Case 6. — Epithelium ovoid and broken up; struma or 
scrofulous pus, with fibro-plastic tissue and large masses of 
fatty matter ; hypertrophy of the epithelial scales. 
Case 7. — Pus exuding, small fat-globules, scrofulous pus- 
corpuscles, and epithelial scales. 
Case 8. — Fat-globules, well marked, and in large quan- 
tities; scrofulous pus-corpuscles with larger cells, having 
smaller enclosed ; epithelium large and hypertrophied. 
Lupus non exedens (Lupus without ulceration). 
Case 1.- — Fat-globules, irregular in form, with epithelial 
scales very large, and pus-corpuscles.
