The following Communications were read :• — 
1. Account of the Extension of the Seven-Place Logar- 
ithmic Tables, from 100,000 to 200,000. By Edward

A bstract. 
In this paper the details were given of the computations made 
for extending the Table of Seven-Place Logarithms to 200,000

100,000 to 200,000.

Professor Blackie.

of Accent in Language.” On the subject of accent and quantity, 
he remarked, especially in relation to the learned languages, the 
greatest confusion had prevailed, and the existing practice was 
altogether unreasonable and anomalous. In articulate sound four 
things had to be distinguished — volume or bulk, force or emphasis, 
elevation and depression, and prolongation or duration. English 
scholars had shown an unhappy incapacity of not being able to 
distinguish between stress and prolongation, and thus had been led 
to introduce the general practice of pronouncing G-reek with Latin 
accents. In laying down the principles by which syllabic accentua- 
tion is guided, four points are to be attended to — significance, 
euphony, variety, and convenience. Fashion, of course, and cus- 
tom have wide sway in this domain; but in the original structure
