SMALL POX AND VACCINATION HOSPITAL. Every poor person, if five years old or upwards, labouring under the casual small-pox, may become an in- patient; and all such patients, being children under that age, are admitted, with their mothers or nurses, on the payment of 1s. 6d. per day for their board. Patients are admitted every day, and at every hour, upon the recommendation of a governor. Vaccination is given daily, from 10 till 1 o'clock, and vaccine lymph gratuitously distributed to all physicians and surgeons who may apply for the same. The Hospital is open for the instruction of medical pupils. A donation of 10 guineas constitutes a governor for life, and 1 guinea yearly an annual governor.

SMALL-POX AND VACCINATION HOSPITAL, instituted 1746, for those attacked with natural small-pox, and for preventing it by vaccination, was first opened at Battle Bridge, St. Pancras, 1767; but this Hospital and site being required for the terminus of the Great Northern Railway Company, the Hospital was rebuilt in a healthy and picturesque situation at the foot of Highgate-hill, at a cost of 20,000l., paid out of the Railway Company's compensation.
