This book is planned for those who are neither doctors nor naturalists. It is, in other words, a popular life of the famous discoverer of vaccination. Few people realize that Jenner was an accomplished musician, a good amateur poet, a fairly good surgeon and an exceedingly proficient naturalist. Many of his essays on birds and animals have a classic quality. The little volume by Dr. Drewitt will be read by many persons who will not care to read the more extensive study in two volumes that was published long ago.
