Showing a few thick crusts remaining upon the face with numerous dull red spots from which the crusts have fallen. [F.] XIV. VARIOLA DESICCATA ET SQUAMOSA. (Twentieth Day.) Figs. 1 and 3 show the dried pustules remaining in the thickened skin of palm and sole after the crusts have fallen elsewhere. [F., P.] Fig. 2 shows the superficial desquamation which follows the falling of the crusts, producing rings of partly detached epidermis. [F.] XV. Fig. 1 shows a peculiar pigmentation sometimes left after the eruption. The central portion, being darker, produces a “bull’s-eye” appearance. [F.] Fig. 2 shows the hypertrophic condition of the scars which occurs in certain cases in place of the usual pitting, and which tends to disappear in time. [H.] Fig. 3 shows severe pitting, a partial loss of hair and eyebrows, and destruction of one eye. [H.] XVI. Fig. 1 shows the typical appearance of a successful revaccination. (Fourth day.) [F.] Fig. 4 shows a small, well-formed vaccination pustule at its height. (Eighth day.) [F.] Fig. 2 shows a large, irregular pustule resulting from scarification of an area of unnecessary extent. (Eighth day.) [F.] Fig. 5 shows an ulcer resulting from infection of the vaccination lesion. [F.] Fig. 3 shows a primary vaccination at its height (eighth day) with a characteristic areola. [F.] Fig. 6, a case of Varicella on the third day. [F.] PREFACE. Whenever a physician is called to a case of suspected smallpox, he confronts a grave responsibility. If young or without special experience, he is apt to feel a sore need of assistance, and, although a book can never take the place of an experienced consultant, it is the object of the present work to render him as much aid as possible. The text aims to be practical rather than elaborate. The plates are reproductions of photographs from life, some of which have been obtained under great difficulty. While many articles on variola have been illustrated by a few photographs of cases, mostly of the pustular type, this work is believed to be the first which has presented illustrations of the smallpox eruption in each of its successive stages. It is sincerely hoped that the reader will find it of service in familiarizing him with the peculiar features of the disease. GEORGE HENRY FOX. SMALLPOX. CHAPTER I. SYMPTOMS AND COURSE.
