A Practical Treatise on Smallpox

A detailed early‑20th‑century guide to smallpox, this work walks listeners through the disease’s outward signs, how doctors of the time identified it, and the therapeutic options then available. Structured into clear sections on symptoms, diagnosis, treatment and vaccination, it blends practical advice with scientific observation, offering a window into medical practice before modern antivirals.

The book’s most striking feature is its collection of colored photographs taken by leading dermatologists, each captioned to show the day‑by‑day evolution of lesions on the skin, face and extremities. These images illustrate everything from the first faint eruptions to the later pustular and crusted stages, providing a vivid visual narrative that complements the written explanations. For anyone interested in the history of infectious‑disease medicine, the treatise offers both educational detail and a compelling, image‑rich portrait of a once‑devastating illness.
