34 PHILOSOPHICAL TRANSACTIONS. [aNNO 1672, 



jin Extract from Mr. FlamsteecTs Letter, written to the Editor from Derby, Nov. l6, 

 1672, concerning the j^ppulses, calculated by hiin for An. 1673 of the Moon, 



and the other Planets, to Fixed Stars, with an Observation of the Planet Mars, 



N°89, p. 5118. 



September last I was at Townley. The first week that I intended to have 

 observed (^ there with Mr. Townley, I twice observed him, but could not 

 make two observations, as I intended, in one night. The first night after my 

 return, I had the good fortune to measure his distances from two stars the same 

 night : whereby I find, that his parallax was very small ; certainly not 30 se- 

 conds: so that I believe the sun's parallax is not more than 10 seconds. 



Having observed the distances and positions of the three stars, by which ^ 

 made his transit, I find, that Tycho errs five minutes at least both in the places 

 and latitudes compared one with another. And certainly he errs as much in 

 many others; so that the labour of M. Hevelius to rectify their places is very 

 needful. Not that I find fault with Tycho ; it is a wonder, considering how 

 difficult it is to set plain sights to a small star, that ever he performed so much, 

 and so well: but if M. Hevelius use not glasses in their room, I fear we shall 

 be but where we were ; and yet without this restitution we cannot expect any 

 thing certain, much less accurate, in astronomy.

 Puebla de los Angelos; the other a Relation of the Voyages of N. N. into the

A Further Account of Veins in Plants, &c. by Mr. Lister, in a Letter of Jan. 8, 



1672-73. N°90, p. 5132. 



We have formerly given you certain reasons for the existence of veins, analo- 

 gous to those in animals, in all plants whatsoever, mushrooms not excepted. — 

 To which we might add, that the skin of a plant may be cut sheer off^ with
