Note 24 — Chapter IV · (continued 2)

A more detailed account of the processes connected with the construction of this telescope, will be found in a paper presented to the Royal Society, in 1827, and published in the Philosophical Transactions of that Society, for 1828, and likewise another paper, published in the Transactions for 1829. From these documents, chiefly, the preceding account has been abridged. See also the ‘Edinburgh New Philosophical Journal’ for Jan.,—April, 1828, and Brewster’s ‘Edinburgh Journal of Science,’ for October, 1829.
