But though his life was thus spent in 
close and severe studies, more for the 
benefit of mankind than his own private 
interest, yet they do not seem to have 
affected, or had any bad influence on, his — 
temper ; for his letters not only disco- 
ver an ease and sedateness of mind, but 
likewise an agreeable cheerfulness and 
pleasantry. Among the Poemata Greca 
et Latina, written by Mr. Henry Jacob, 
who was then much celebrated for his 
_skillin philology, there is this epigram 
upon Mr. Briggs:

This edition, soon after his death, was 
translated into English, with the follow 
ing title: 
Logarithmical Arithmeticke, or Tables 
of Logarithms, for absolute numbers 
from an unit to 1,000,000, as also for 
signs, tangents, and secantes, for every 
minute of a quadrant, with a plain de- 
scription of their use in Arithmeticke, 
Geometry, Navigation, &c. These num- 
bers were first invented by the most ex- 
cellent John Neper; Baron of Marchis- 
ton, and the same were transformed, and 
the foundation and use of them iiluse 
trated with his approbation, by Henry 
Brigges, Sir Henry Savile’s Professor of 
Geometry, in the University of Oxford : 
the uses whereof were written in Latin by. 
- the author himself; and since his death 
published in English by diverse of his 
triends, according to his mind, for the 
benefit of such’ as understand not the
