d'Oxford, les a change, & leur Nature, Origine, & Usage illustre selon rinten- 

 tion du dit Neper, La description est traduite du Latin en Frangois, la 

 premiere Table augmentee, & la seconde compose'e par Adriaen Vlacq. Dieu 

 nous a donne I'usage de la vie et d'entendement, plus qu'il n'a fait par le 

 temps passe. [Small typographical ornamentl. A Goude, Chez Pierre 

 llammasein. M.DC.XXVIII. Avee Privilege des Estats Generaux. fol.

 of the title is printed in red. § 4. 



[The radius is erroneously describedin the above two titles as 10,00000,00000 ; 

 it is really 1,00000,00000, viz. the logarithms are given to ten decimal places.] 



Vlacq, Adeian. Logarithmieall arithmetike. or tables of iogarithmes for 

 absolute numbers from an unite to 100000 ; as also for Sines, Taugentes 

 and Secantes for everj^ Minute of a Quadrant : with a plaine description of 

 their use in Arithmetike, Geometrie, Geographic, Astronomic, Navigation, 

 &c. These Numbers were first invented by the most excellent lohn Neper 

 Baron of Marcliiston, and the same were transformed, and the foundation 

 and use of them illustrated with his approbation by Henry Briggs Sir Henry 

 Savils Professor of Geometrie in the Universitie of Oxford. The uses 

 whereof were written in Latin by the Author himselfe, and since his death 

 published in English by diverse of his friends according to his mind, for the 

 benefit of such as understand not the Latin tongue. Deus nobis usuram 

 vitoe dedit, et ingenii, tanquam pecuniae, nuUa pi-aestituta die. [Printer's 

 device and motto, Anchora spei.] London, Printed by George Miller. 1G31. 

 fol. (54 pp. of trigonometry &c. followed by " a Table of Latitudes" (8 pp.), 

 and then the logarithmic tables, unpaged). § 4.
