 William Wallace, LL.D., late Professor of Mathematics in the 

 University of Edinburgh, was descended from a family in humble 

 circumstances, which had been settled, for some generations, at 

 the village of Kilconquhar in Fifeshire. His grandfather inherited 

 a small property, the greater part of which he lost through injudi- 

 cious management. His father established himself at Dysart, a sea- 

 coast burgh in Fife, as a manufacturer of leather and shoes for ex- 

 portation, and for some years carried on a considerable trade, which, 

 however, was ruined by the breaking out of the American war. The 

 subject of this memoir was born at Dysart on the 23rd of September, 

 1768, and was the eldest of a numerous family. 



In adverting to the circumstances of his early life, he used to re- 

 late that the first rudiments of his education were received from an 

 aged widow in the town, who kept a school for children, and retailed 

 small wares. About the age of seven he was removed to a school 

 of a better class, in which the principal branch of instruction was 

 arithmetic. In this science, however, he had already been grounded 

 by his father, and had made considerable proficiency in it before he 

 was advanced to that department in the routine of his school pro- 

 gress. His attendance at school — for instruction it can scarcely be 

 called — was discontinued when he had reached the age of ten or 

 eleven years ; and, according to his own statement, all he owed to 

 the schoolmaster was the power of reading, and of forming, in a very 

 indifferent way, characters by writing. His knowledge of arith- 

 metic he owed to his father, and to his own strong liking for the 

 subject.
