also those of two or three of his next neighbours; and some ancient mulberry 

 trees, planted in a line towards the north, seem to confirm this conjecture. 



When the death of John Tradescant happened. Dr. D. has not been able to 

 discover, no mention being made of it in the register book of Lambeth church. 

 A singular monument was erected in the south-east part of Lambeth church- 

 yard, in 1662, by Hester, the relict of John Tradescant the son, for himself 

 and the rest of this family, which is long since extinct.* This once beautiful 

 monument has suffered so much by the weather, that no just idea can now, on 

 inspection, be formed of the north and south sides. But this defect is happily 

 supplied from 1 fine drawings, preserved in Mr. Pepys's library at Cambridge. 

 We see on the east side, Tradescant's arms; on the west, a hydra, and under it 

 a skull ; on the south, broken columns, Corinthian capitals, &c. supposed to be 

 ruins in Greece, or some other eastern countries; on the north, a crocodile, 

 shells, &c. and a view of some Egyptian buildings. Various figures of trees, 

 &c. in relievo adorn the four corners of this monument. 



XIII. Of the Intense Cold in the Months of Jan. 1767, and 1768, and Nov. 



1770, observed at Franeher. By J. H. Van Swinden, Prof. P kilos, in the 



Acad, of that place, and Fellow of the Harlem Soc. From the Latin, p. 89. 



In Jan. 1767, Fahrenheit's thermometer showed degrees as follow: Jan. Q^Q^ 

 a. m. 16°; at lO'' p. m. 2°.— Jan. 7^ 1\^ a. m. — 1°; at noon -f 12°; at 7'' p. m. 

 5°; at g^ p.m. 7°- — Jan. 8'^ T\^ a. in. 12°. — Here the lowest was — 2° or 2 

 below O, the mercury being all sunk down into the bulb. But M. Vander Bild 

 observed it as low as — 5. 



In 1768, Jan. 3 it was as low as — 3\. 



In 1770, the lowest in Nov. was -f 9, viz. on the 20th, at 7t*'« 



XIF. An Inquiry into the Quantity and Direction of the Proper Motion of Arc- 

 turus; with some Remarks on the Diminution of the Obliquity of the Ecliptic, 

 By Tho. Hornsby, M.A., Savilian Prof, of Astron. Oxford, and F.R.S. p. 93. 

 By comparing ancient with the best modem observations, it appears that some 

 of the fixed stars have a proper motion, independent of any motion hitherto 

 known in our own system; or that, in other words, the angular distances of the 

 fixed stars have not always continued the same, and in some of them the altera- 

 tion is so very considerable, as to be easily perceived in the course of a few years, 

 with instruments accurately made, and nicely adjusted. Of all the stars visible
