VOL. VI.] PHILOSOPHICAL TRANSACTIONS. (531 



So that now we have had three demonstrations of this quadrature, in his 

 Rosetum, in his first paper, and in his third, and this common fault in all of 

 them, that they equally prove the proportion by him proposed, or any other 

 what you please. But such his demonstrations use to be. 



And this is what I thought fit to say to Mr. Hobbes's four papers, rather to 

 satisfy the importunity of others, than because I thought them worth answer- 

 ing : And submit the whole, with all respects, to the Royal Society, to whom 

 Mr. Hobbes makes his appeal. 



His Fourth Part, 



Which came out since the three former were answered, containing some faint 

 endeavours to re-assert some things in them, is but mere trifling, or worse. 



What he would therein insinuate concerning God, that we may as well prove 

 Him to have had a beginning, as that the world had, smells too rank of Mr. 

 Hobbes. We are not to measure God's permanent duration of eternity, by 

 our successive duration of time: nor His entire ubiquity, by corporeal ex- 

 tension. 



What in it concerns mathematics, whether his own or others, is so weak and 

 trivial, and said only, that he may seem to say something, though nothing to 

 the purpose, that I shall trust it with those to whom he makes his appeal, without 

 thinking it to need any reply ; the view of what he writes against, being a 

 sufficient answer to all he says. 



New Observations of Spots in the Sun; made at the Royal Academy of 

 Paris, the Wth, 12th and 1 3th of August I67I; and translated from 

 the French, as follows. N" 75, p. 2250. 



It is now about twenty* years since astronomers have seen any considerable 

 spots in the sun, though before that time, since the invention of telescopes, 

 they have from time to time observed them. The sun appeared all that while 

 with an entire brightness, and Signor Cassini saw him so the ninth of this 

 month of August. 



But the nth of the same, about six o'clock at night, being furnished only 

 with a three feet glass, he remarked in the sun's disk two spots very dark, dis- 

 tant from his apparent centre about the third part of his semidiameter. And 

 that he might the more exactly note their situation, in respect of the several 

 parts of the world, he made use of two very fine threads, cutting one another 



• See number 74, p. 6 15, whence it will appear, that some such spots were seen here in London, 

 A. US60. And M. Picard affirmed to Dr. Fogelius at Hamburgh, that he had seen some in Octo- 

 ber l66l J witness the said Doctor's own letter, written to the editor, August 1 1th last.
