Pièce 118 - Letter from Thomas Perronet Thompson

1 p.

Gives WW a copy of a second edition of his book on Parallels ['Geometry without Axioms. Or the First Books of Euclid's Elements', 1830, in which he tries to establish the theory of parallel lines without recourse to any principle not founded on previous demonstration]: 'It contains some corrections, and alterations meant for improvements; of which the only one worth specifying, is the alteration in the lemma in the notes, in which perhaps after all, the stress of the argument resides'.
