= Copy of the trade edition, in "P. Noordhoff - Groningen" binding, of the orig. thesis (publ. in the same year). DSB II, p.512: "(...) Brouwer reacted vigorously to the debate between Russell and Poincaré on the logical foundations of mathematics. These reactions were expressed in his doctoral thesis, Over de Grondslagen der Wiskunde (...). In general he sided with Poincaré in his opposition to Russell's and Hilbert's ideas about the foundations of mathematics. He strongly disagreed with Poincaré however, in his opinion on mathematical existence. To Brouwer, mathematical existence did not mean freedom from contradiction, as Poincaré maintained, but intuitive constructibility."

= Hoogendoorn, Ceu 05, 1.1. Bierens de Haan 839; Simoni C85; DSB III, p.181. The second of the two major works by Van Ceulen, published 5 years after his death by his widow. Probably written only in part with an educational purpose for use at the university of Leyden at which Van Ceulen taught, it should primarily be seen as a theoretical work on the fundamentals of arithmetics and geometry (see C. Vlek, Ludolf van Ceulens Arithmetische en Geometrische Fondamenten, master's thesis available online). SEE ILLUSTRATION PLATE LIII.

His epochal 1872 publication, Stetigkeit und irrationale Zahlen, gave the first rigorous definition of the system of real numbers, laying the foundation for much of modern day real analysis and point-set topology. Was sind und was sollen die Zahlen, his follow-up work, elaborates on his attempts "to derive a purely logical foundation for arithmetic, and devised a number of axioms that formally and exactly represented the logical concept of whole numbers" (DSB). Extremely rare, even in the 2nd edition. Poggendorf I, p.534; DSB IV, p.1-5.

= First Dutch translation of "Entwicklung der Gall'schen Theorie über das Gehirn" (1803). Franz Joseph Gall (1758-1828) was a German anatomist, physiologist, pioneer in ascribing cerebral functions to various areas of the brain (localization), and creator of phrenology, or the practice of divining individual intellect and personality from an examination of skull shape. According to Gall the surface of the skull faithfully reflects the relative development of the various regions of the brain. Hirsch III, 758/9; BMN I, 108.
