Copied from the original letter in the possession of Mrs. Giles. No. 123.) Letter from Mr. Flamsteed to Sir Isaac Newton. The Observatory, Sep. 14, 1706. Sir, I have consulted Tycho's Mcchanica, where he says that at that time, when he wrote it, he was 50 years of age complete, and that his volumes contained the accurate observations of 21 years; which shews they commenced in the year 1575.

The second part is concerning the comet of 1577; so that we have the observations of but 3 of his 7 comets: and of those, only such as he thought fit to employ. This makes me think that his observations of the comets is made a book by themselves, and that probably it is still to be found in Denmark, with the 7 or 8 years' observations that are missing. Whatever his Royal Highness determines concerning the rest of Tycho's works, it may be much for his honor to bestow these on the world, with the errata of the German edition, if he can procure the originals, as I doubt not but...
