It is likewise to be remark'd, That a City situated upon the Sea, must needs have an unwholsom Air, if it be towards the South or the West; for generally the Heat weakens Bodies, and the Cold strengthens them; and so we see by Experience, that those who go out of a Cold Country into an Hot, have great difficulty to keep themselves in Health; whereas on the contrary, the Inhabitants of Hot Countries who go into Colder, have generally good Health. The Ancients were accustomed to judge of the Quality of the Air, Water and Fruits, which might render a place wholsome by the Constitution of the Bodies of those Beasts which were nourished there, and to this End they consulted their Entrails; for if the Liver was Corrupted, they conjectured that the same thing must happen to Men that should Inhabit in that place. ART. II. _Of the Form and Situation of the Building._ [Sidenote: _Lib. 1. Chap. 6._] After having chosen a wholsome place, the Streets must be laid out according to the most Advantageous Aspect of the Heavens, and the best way will be to lay the Streets out so, that the Wind may not come directly into them, especially where the Winds are great and cold. The Prospect of Private Mens Houses is made more or less Commodious, by the Openings which are differently made, to receive the Air and the Light according to the Quality of the Parts that are in the Fabrick. [Sidenote: _Lib. 6. Chap. 9._] For the Cellars, Granaries, and generally all places that we wou'd Lock up, or keep any thing in, should be exposed to the North, and receive very few Rays of the Sun. [Sidenote: _Lib. 6. Chap. 7._] The different Use of the Parts which Compose the Buildings, do likewise require different Situations; for the Dining-Rooms in Winter, and the Baths among the Ancients, were always turned to the West, for that Situation made them warmer, because the Sun then shone upon them, about the time they were wont to make use of those Apartments. The Libraries ought to be turned to the rising Sun, because they are generally made use of in the Morning; besides, the Books are not so much damnified in Libraries so situated, as in those which are turned to the South and West, which are subject to Worms and a certain Humidity which engenders Moldiness, and consequently destroys the Books. The Dining-Rooms for the Spring and Autumn, should be turned towards the East, to the end, that being covered from the great force the Sun hath when it is near Setting, they may be cooler about the time they are to be made use of. The Summer Apartments must be turned to the North, that they may be fresher and cooler. This Situation is likewise very proper for Closets, which are adorn'd with Pictures for the Light which is always equal, represents the Colours always alike.
