 of Vitruvius's copiers. 



I shall conclude this discourse with this remark, that proportion, and a plain 

 uniformity, even in the minutest parts of building, is to be observed, as this 

 miserable ruin of Roman workmanship shows. In our Gothic buildings there is 

 a total neglect of the measure and proportion of the courses, as if that was not 

 much material to the beauty of the whole, whereas indeed in nature's works it 

 is from the symmetry of the very grain that much of the beauty arises.

On certain Conjunctions of the Planets Jupiter and Saturn. By J. F. [John 

 Flamsteed']y Astron. Reg. et R.S.S. N° 149, p. 244. 



Whilst common observers have wondered to see the two superior planets Sa- 

 turn and Jupiter continue so near each other this whole year, and our astrologers 

 have affrighted them with fearful predictions of direful events to succeed this 

 appearance, the more judicious are desirous to know how often and at what 

 time their conjunctions happen, that by comparing their tables of these planets' 

 motions with the observed appearance, they may be the better able to correct 

 them, and render them more agreeable to the heavens. Examining our ancient 

 ephemerides, I do not find that three conjunctions of Saturn and Jupiter have 

 ever happened in one year's space, since they were first in use, till this present. 

 Those of Moletius, calculated from the Alphonsine tables, indeed make three 

 in the space of 8 months, between August 1563, and April 1564 inclusive. But 

 the ephemerides of Stadius, calculated from the Prutenic, make only one, on the 

 26th of August, of which Junctinus gives us the following observation, in the 

 preface to his astronomical tables. Anno 1563, Aug. 24, 14h. 30 m. P. M. 

 Jupiter on the north-side as it were covered Saturn, which was on the south- 

 side, and both these planets were at the end of 28° of Cancer. Riccioli hence 

 concludes that the planet Jupiter covered some part of Saturn at this time. But 

 without reason, for the words quasi cooperiebat intimate not that the one did 

 corporally cover the other, but rather that there was some small interval between^ 

 them. The Caroline tables make the visible latitude of Saturn now 1 T 43'''', of 

 Jupiter 20' 10', both north, the conjunction being some few days past : but be-
