very accurate, after a minute examination, while preparing materials for his large map of Scotland.
On his return to Edinburgh in 1743, Mr Bryce gave very efficient aid, with, his friend the reverend Mr Wallace of Haddo's Hole church, in verifying the necessary calculations submitted to them by doctor Webster, previous to the institution, by act of parliament, of the fund for a provision for the widows of the Scottish clergy; the regular increase of which since, and its present flourishing state, form the best encomium of those who laboured for its establishment.
In June, 1744, he was licensed to preach, by the reverend Presbytery of Dunblane; and having received a presentation by James, earl of Morton, to the church and parish of Kirknewton, within the Presbytery of Edinburgh, he was ordained to serve that cure, in August, 1745. From his knowledge of the inland geography of Scotland, and line of the roads, he was enabled, this year, to furnish the quarter-master general of the army of the Duke of Cumberland with important information regarding the march of the forces, in subduing the rebellion. In the winter of 1745, and spring of 1746, he taught the mathematical classes in the university of Edinburgh, at the desire, and during the last illness of Professor Maclaurin, who died in June following. Mr Bryce expressed his sorrow for the loss of his friend in verse, of which the following is a specimen:—
Yon angel guards that wait his soul,
Amaz'd at aught from earth so bright,
Find nothing new from pole to pole;
To show him in a clearer light.
Joyful he bears glad news[1] on high,
And tells them through celestial space;
See Newton hastens down the sky,
To meet him with a warm embrace!
The list'ning choirs around them throng,
Their love and wonder fond to show;
On golden harps they tune the song,
Of Nature's laws in worlds below.
O Forbes, Foulks, loved Morton, mourn;
Edina, London, Paris, sigh;
With tears bedew his costly urn,
And pray Earth light upon him lie.
In the year 1750, having occasion to visit Stirling, and knowing that, by an act of the Scottish parliament, this borough had the keeping of the Pint Jug, the standard, by special statute, for weight and for liquid and dry measure in Scotland, he requested a sight of it from the magistrates. Having been referred to the council house, a pewter pint jug, which had been kept suspended from the roof of the apartment, was taken down and given to him; after minutely examining it, he was convinced that it could not be the standard. The discovery was in vain communicated to the magistrates, who were ill able to appreciate their loss. It excited very different feelings in the mind of an antiquary and a mathematician; and resolved, if possible, to recover this valuable antique, he immediately instituted a search; which, though conducted with much patient industry during part of this and the following year, proved un-
- ↑ A few days before his friend's death, he saw him institute a calculation for ascertaining the proportion that existed between the axis of the earth and the diameter of its equator. It proceeded on data sent him by the Earl of Morton, president of the Royal Society, consisting of observations made in Peru by the French mathematicians, and communicated at London by Don Antonio, who was taken prisoner at Cape Breton. The proportion ascertained was very nearly that which Sir Isaac Newton had predicted; being as 221: 222, and afforded particular gratification. These are the news he is supposed to bear.
