A Plague Bubo developed in the left groin * * * 25 August: Further vomiting of dark green matter. The tongue is dry and has a slightly brackish appearance. The pulse is light and quick. Respiration is jerky, the features are distorted. In the night death occurs.
On 7 August at 8 o’clock in the evening, Mohammed Ben Ali who has been condemned to death was dressed in the shirt, underwear, and jacket of a person seriously ill with the plague. Immediately thereafter he was placed in the patient’s bed. Until the 22d no symptoms of disease. On the morning of the 23d severe outbreak of the disease. Tottering gait, then walking impossible. Extreme loss of energy, appearance of being seriously ill * * *
On 18 August we inoculated a person condemned to death with blood through 4 vaccinational cuts in the fold of the right arm. This blood was taken from a head vein of a plague patient who had been ill for 2 days * * *
On 22 and 30 August a second person, condemned to death, with a plethoric constitution and of strong build was inoculated with blood. The first time in a fold of the left arm and in the right groin area, the second time in the opposite positions. On the area of the vaccination only the natural reddening and infections caused by the vaccination instrument appeared, nothing else.
“A third person condemned to death was inoculated with the fluid taken from a Plague Bubo in the groin and in the shoulder. This same person had dressed in the clothes of a plague patient 20 days previously and had contracted the plague with all its severe symptoms. The skin and tissue of this experimental subject remained refractory towards any absorption of the poison. Even when the inoculation with blood was repeated 8 days later, no disease resulted.”

In 1791, the teacher Plett of Holstein successfully vaccinated three of his landlord’s children in Starkendorf near Kiel. Later on when an epidemic occurred they did not contract the disease, while their brothers and sisters which had not been vaccinated fell sick.
