    Drawing 6 was taken. The epithelial structures are more numerous than in the last case, and the branching and anastomosis of the cell-nests more general. The central cell-nests are fairly repre- sented in Drawing 6. The peripheral nests resem- ble in shape Drawing 3, though here the develop- ment has not reached a sufficiently advanced stage to show many epithelial cells. Here we see the central thread of fibres, dividing the alveolus in its long diameter. A still earlier stage is represented in D rawing 4, at a point situated on the extreme borders of the growth. Here the cells resemble the connective tissue cells, and the axis of the alve- olus is represented by a delicate blood-vessel. The different stages of development observed in this specimen are well shown in the sections from which the above drawings were taken. Case III. — Male, ret. 42. Disease began as a pimple on the right ala nasi, eleven years ago. In consequence of scratching it, an ulcer formed which steadily increased in size ; was twice removed by a plaster.
