A slip by Anthony Wood, pasted here, shows that Aubrey recalled the MS., probably to make additions to it:—

'Mr. Aubrey,

I beseech you as you have been civill in giving this book to me at Oxon in Sept. 1681, so I hope when you have done with it you'l returne every part of it againe to your servant,

Ant. Wood.'

As originally made up, this 'Auctarium' contained four leaves at the beginning (for an index[30]), and leaves foliated 1-38 (of which 12 and 13 are now[31] missing).

The second part[32] of the MS. extends over foll. 69-103 in the present marking.

Aubrey, on fol. 69, writes the title:—

'An Apparatus for the lives
of our English mathematical writers
by
Mr. John Aubrey, R.S.S.
March 25, 1690.'

As originally made up, this treatise consisted of one leaf (for an index[33]) and pages marked [1]-46 (of which pp. [31]-38 are now missing).

The history of this treatise is fully set out by Aubrey in some notes in it and in the other MSS.:—
