"For... part of the first tractate, the examples are all (or most of them) the same as are Mr. Wells in his Sciographia... The second tractate was, partly a translation out of Magnon, by Mr. Thomas Gibson: and the third is partly Mr. Samuel Foster's... The seventh tractate came to my hands in a Latine manuscript of Mr. Samuel Foster's written with his own hand in anno 1640... The ninth tractate is wholly Mr. Samuel Foster's... The tenth tractate also, is wholly his, and was... transcribed from a manuscript of his, which he... entituled Gold... The eleventh tractate... is Mr. Foster's also"-Pref
