reftraint is laid upon, what I may call per- 

 fpiration in the tender extremities of the head 

 of an Oak ; when at the fame time, it is 

 falutary to the Vv^hole to have the natural ef- 

 fluvia thereof uninterrupted, or in other 

 words, it's atmofphere not abridged. From 

 whence why may it not be concluded, that 

 the fap after feveral flattering invitations up 

 into the bodies and boughs of Oaks in the 

 winter, by ftarts of warm intervals, becomes 

 greatly infpifTated, and thereby unapt to re- 

 turn to the Jiatu quo of it's prior liquidity ? 

 Becaufe the moft vifcous, or ligneous parts 

 of it, muft thereby be much condenfed, and 

 not inchnable to be fluxible any more. And 

 that furely muft be the cafe, if piercing winds 

 can dry, and as parching heat contract. If 

 10, what can thofe fuffering patients do? 

 when fettled, fhining feafons come — Able 

 even to nourilh the orange and the citron 

 grove ? And inilead of oriental blafts, the 

 foft vegetating breath of heaven ; perhaps 

 feconded by a vernal ardour little inferior to 

 a fummer's fun. What ? but difcharge the 

 tenuious plethora, that happens to be fo, qua 

 data port the natural paflages being /ro hdc 

 vice, infufficicnt voidures.
