But all these Precautions are to be compleated in the _Lazarettos_, so called from the original Intention of them for the Recovery of Persons sick of the Plague, but worthy now a better Name, as they are the Deposits of the Publick Safety, which therein exercises its Precautions. These are of a double Use; for the Purification of Persons and Merchandize, separately, in Times of Health; and for the Recovery of sick infected Persons, and the Purification of dangerous Household Furniture, in Times of the Plague; to which Use are also converted other Insular Places which are scattered among the Marshes round us. The first Thing to be considered in these _Lazarettos_ is their Situation. They should not be so near the Town as to cause any Danger, nor so far distant as not to be under the Eye of the Magistrate, and within Reach of all proper Provision and Assistance. There are two _Lazarettos_ at _Venice_, the Old and the New; the first distant two Miles and more, the other a little above Three from the City. Each forms a separate Island, which has nothing contiguous to it, and cut off from all Communication. Each takes up a large Space of Ground, shut in all round by Buildings washed by the Waters, which serve for a Wall and Guard: They have no Openings outward for any Thing to go out at, for every Thing must go out at the same Gate at which it entred. The Length of the Ground the first stands on is one hundred and five Geometrical Paces of five Feet each; the Breadth eighty-five; the whole Circumference three hundred and eighty. The second is somewhat larger, _viz._ one hundred and twelve long, ninety-two broad, and four hundred and fourteen in Circumference. The Structure of each is remarkable for its Capaciousness, but much more so for the Contrivances of Convenience and Security. At the Entrance is the _Prior’s_ House, which is always free, disjoined from every Place belonging to the Quarantine, but so contrived, as to command the greater Part of them. All the rest of the Ground is taken up, either by Buildings to lodge Passengers, or in large Courts all surrounded with open Sheds, under which the Merchandizes are exposed to the Air, and preserved from the Weather; or else with great Sheds all round walled in, but with Holes in the Top to let in the Air; which serve for the same Use. What is most to be admired in the Contrivance of them is, that they are divided and subdivided into many Offices for Quarantines, and of different Kinds, in such a Manner, that each has its peculiar Ingress, without giving or receiving any Inconvenience from the other, in order to prevent the Danger of any Communications; in which the very Essence of the Regulations consists. As to the Places destined for the Reception of Persons; in the first Place, they are separated from every other, which serves for the Purification of Goods; and with great Reason; for if the Proprietor had Leave to visit his Cargo, whilst
