OLD BOOK HUNTER

OLD BOOKS REVIEWED. MARKET INFORMATION.

Issue No. 3 — September 11, 2026

Old Book Hunter is an informational publication, not a solicitation to buy, sell, or invest.

This issue's five: a 1689 mathematics treatise from a member of Malebranche's philosophical circle — reunited here as a complete two-volume set after turning up as two separate, unmatched listings from the same seller — a genuine 18th-century treatise devoted entirely to the design of chimneys, Thomas Bewick's landmark achievement in wood-engraved natural history illustration, an eccentric naturalist's own strange, occasionally alarming account of the South American jungle, and a complete 19-volume set of Voltaire's collected philosophical writings surviving intact after 250 years. If any of it catches your eye, the full write-up — including why it matters and what to watch for — is one click away.

Nouveaux Éléments des Mathématiques — Complete 2-Volume Set (Tome I & II), 1689

Jean Prestet · 1689

$527

Jean Prestet moved in Nicolas Malebranche's philosophical circle and was among the first to write mathematics in French rather than Latin, helping bring algebra to a wider audience — Abraham de Moivre reportedly taught himself the subject from an earlier edition of this same work. But this particular edition carries a more specific, citable distinction: scholars writing in the peer-reviewed journal Historia Mathematica have identified pages 140–150 of Volume I as containing Prestet's early precursor work toward the Fundamental Theorem of Arithmetic — the principle that every integer has a unique prime factorization, not rigorously proven until Gauss in 1801. The scholarship is careful here: Prestet never states the theorem outright, and it's genuinely debated whether he grasped its full implications. But the fact that mathematicians are still parsing his 336-year-old corollaries to answer that question is itself a real mark of the book's significance.

Caminologie, ou Traité des cheminées, contenant des observations sur les différentes causes qui font fumer les cheminées, avec des moyens pour corriger ce défaut

Pierre Hébrard · 1756

$324

An entire 18th-century treatise on chimneys and smoke control, published at Dijon by F. Desventes in 1756 and attributed in library catalogues to Pierre Hébrard — a genuinely odd corner of the technical literature that sits at the junction of architecture, domestic comfort, and early applied physics of draught and combustion. Institutional interest is real rather than notional: the Metropolitan Museum holds a copy in its Drawings and Prints department (Harris Brisbane Dick Fund, 1937), and the ETH-Bibliothek copy has been digitised in e-rara.

[ THE BEAUTIFUL ONE ]
A General History of Quadrupeds. The Figures Engraved on Wood by T. Bewick

A General History of Quadrupeds. The Figures Engraved on Wood by T. Bewick

Thomas Bewick (with Ralph Beilby) · 1790

$750

Bewick's first major book put his wood engraving in front of a wide audience and made the medium a serious vehicle for natural history illustration, with the animal figures cut by Bewick and the descriptive text drafted by his partner Ralph Beilby and revised by Bewick. It was commercially successful on a scale unusual for a provincial Newcastle imprint, running to seven editions and some 14,000 copies, which is why the 1790 first is the edition collectors chase.

[ THE WEIRD ONE ]
Wanderings in South America, the North-West of the United States, and the Antilles, in the Years 1812, 1816, 1820, and 1824

Wanderings in South America, the North-West of the United States, and the Antilles, in the Years 1812, 1816, 1820, and 1824

Waterton, Charles · 1825

$400

Waterton's Wanderings is one of the best-known first-hand British accounts of the Guiana interior and the Antilles, mixing field observation of tropical birds and animals with the notorious set-pieces (the ride on the cayman, the search for curare) that made it a durable classic of travel writing. The 1825 quarto is also the first appearance of his "Nondescript" frontispiece, the taxidermied composite creature that fed his reputation as a naturalist-eccentric. Waterton rode on the backs of caimans to study them up close, reportedly kept preserved human remains in his home, and the book's "Nondescript Man" is a bizarre composite creature he fabricated from animal parts that nearly caused a public uproar when unveiled.

[ SOMEBODY SHOULD BUY THIS ]
Nouveaux Mélanges Philosophiques, Historiques, Critiques, &c. &c.

Nouveaux Mélanges Philosophiques, Historiques, Critiques, &c. &c.

Voltaire (François-Marie Arouet) · 1765-1776

$1,361

The Nouveaux Mélanges are the vehicle Gabriel Cramer built in Geneva from 1765 onward to carry Voltaire's short pieces on religion, politics, history and literature, and several of those texts appear here in their first printing. The series grew well past its originally planned three volumes into a long collection that Bengesco treats as running to nineteen volumes — making a complete run a substantial slice of late-Voltaire publishing in one place.

Hunter's lesson

Reuniting Orphans

This issue's Bargain is only half the story on the page — Jean Prestet's Nouveaux Éléments des Mathématiques, Tome I and Tome II, 1689. Neither listing said the word "set." Neither mentioned the other. They turned up separately, from the same seller, at different prices, with nothing in the metadata linking them — just two old books that happened to share a title, a publisher, and a year. It took actually looking — reading both descriptions side by side, checking that Tome I ended where Tome II began, confirming the bindings matched in style and condition — to recognize that these weren't two random books. For reasons unknown, perhaps perceived value, the seller saw it fit to sell the volumes individually. But almost always the set is worth more than the sum of the parts. That's the part worth sitting with. A listing tells you what a seller decided to type. It doesn't tell you what a book actually is. The only way to catch two orphaned volumes finding their way back to the same shelf is to look past the text and actually study the object — the physical details a database field can't capture, and a keyword search will never surface. Finding a pair like this isn't quick, and it isn't guaranteed. Most of the time, a volume's other half is genuinely gone — sold decades ago to a different buyer, on a different continent, and never coming back. But every so often, patience turns up a real reunion. That moment — two halves of the same book, separated for centuries, found again in the same place at the same time — is one of the quiet, specific pleasures of using human judgment.
