under Purification, his Coming might put a Constraint upon, or interrupt the Course of Management, through his Concern for preventing any Injury to the Merchandize. _2dly_, They are also separated from each other, though there are a greater or less Number of Rooms contiguous, for the Convenience of a greater or less Number of Passengers, who may arrive at one Time from the same Parts, all having different Ingresses, different Stairs, and no Communication. The Sheds, which inclose the Court Yards, are so disposed, that you cannot pass from one Court to another, all the Gates being kept shut. Each of these Sheds is terminated by a particular Building for the Abode of the Guardian and of the _Bastazi_, who have the Care of the Merchandize exposed under it. The great Sheds have also their Convenience, their Use, and Security. Ample Room is to be given to the Merchandizes, that they may, without being damaged by Weather, be penetrated by the Air; and become at, to be handled; and the Persons are also to be lodged, at Large, conveniently, without occasioning Mixture in the great Numbers of them, or in the Variety of their Quarantines: An Idea of which may perhaps best be had, by considering that the old _Lazaretto_, with only Eight Places for the Purification of Goods (each of them subdivisible into many more) can give Reception to 6730 Bales of Merchandize at once, coming from various Parts. And if one confines only to six different Quarantines, the Quarters appointed for Persons (each of which is subdivided into 13 Rooms) above 294 Persons may be easily and commodiously lodged there at once. The New one, is more capacious; takes in an equal Number of Bales, but has somewhat under 200 Rooms for Passengers, and has sometimes furnished Accommodations for the Quarantine of 4000 Soldiers and 200 Horse, at Times when it was not incumbered with Merchandize. As I need not be more diffuse upon the Description of them, I come now to the Forms observed in them. An Officer called a _Prior_ superintends in each. Great Care is taken in Choice of him, always taking Subjects of the Order of Citizens, and changing him every Fourth Year; and no one can be ever qualified for this Officer, who has either Consanguinity or Connexion with any of the Magistrate’s Officers, or that is interested in any Vessel, or has any Concern in Trade of any Sort. He has a House within the Inclosure of the _Lazaretto_, as has been said, in which he is obliged to reside constantly; never being to leave it, except in the sole Case of attending the Magistrate’s Orders; then leaving a Subaltern in his Room, called the _Sub-Prior_, who is also his Assistant.
