Early Logarithmic Tables. 373 



with the translation of Joannis Neperi Rabdologia, which he gave 

 in the volume just described. In the second volume he pur- 

 posed to give the translation of Henrici Briggii Arithmetica 

 Logarithmica and the Tables of Edmund Gunterus [Professor in 

 Astronomie tot Londen] ; but he cautions the reader to have 

 some patience till that second volume be printed [" verwachten 

 met patientie, tot dat het Tweede Deel voldruckt is "] . 



Now this second volume has never appeared; and by and by 

 I will give a conjecture why not. 



At the same time that the first volume appeared, at least with 

 the same date [4 September int Jaer 1626] he gave another 

 work with the title Nievwe || Telkonst, || inhovdende de || 

 Logarithmi voor de ghe- || tallen begiunende van 1 tot 10000, 

 ghemaeckt || van Henrico Briggio Professor || van de Geo-

Pages viii (not paged) ; A-D (pages 1-51), A-M (169 pages 

 not paged), A-F (91 pages not paged, in octavo). The first eight 

 pages contain the title, the privilege (again to the name of 

 Adriaen Vlack, as before) , the preface, and three sets of verses by 

 Andreas Junius (different from those in the first volume). In the 

 preface de Decker rejects the logarithms of Neper, and adheres 

 to those of Briggs [" om d'eerste Logarithmi te verwerpen, ende 

 dese aen te nemen "] ; and after speaking of his editing the second 

 volume, that will become greater than the first one ["ende nadien 

 dit grooter sal zijn als het Eerste Deel"], and therefore require 

 some time for printing, announces that he is willing to give a 

 Manual for some amateurs' sake that they may profit thereby 

 in the mean time [" Maer alsoo eenige Liefhebbers verlanghen 

 het gebruyck daer van te moghen sien, ende doch eenighe 

 Handtboeckxkens van doen hebben, soo hebben wy dit doen 

 Drucken"]. For this reason he gives the logarithms from 1 to 

 10,000, taken from the { Arithmetica Logarithmica Henrici 

 Briggij/ and a Table for Sines &c. of Edmund Gunter. The 

 first Table occupies the sheets A to M in 169 pages, and has the 

 Latin title : —
