Waddell was an orator of very exceptional power. His skill as a dialectician was displayed in a series of lectures on Ronan's ‘Life of Jesus,’ delivered in Glasgow City Hall before large audiences in 1863, and afterwards published. His profound admiration for Burns led to his issuing a new edition of the powers with an elaborate criticism (Glasgow, 1867—9, 4to). He presided at the meeting held in Burn’s cottage on 25 January 1859 in celebration of the poet’s birth, and then delivered an impassioned eulogy on Burns.
His chief historical work was a volume entitled
Ossian and the Clyde, in which he sought to confirm the authenticity of the Ossianic poems by the identification of topographical references that could not be know to Macpherson. He also contributed a remarkable series of letters to a Glasgow journal on Ptolemy’s map of Egypt, showing that the discoveries of Speke and Grant had been foreshadowed by the old geographer. He took a keen interest in educational matters, and was a member of the first two school boards in Glasgow. His most original contribution to literature was a translation of the Psalms of David from Hebrew into the Scottish language, under the title
The Psalms: frae Hebrew intil Scottis, in which he showed his profound linguistic knowledge. This work was followed in 1870 by a similar translation of Isaiah. In the early part of his career he attracted much notice by lectures which he delivered in London and the principal Scottish towns. Between 1882 and 1885 he edited the Waverley novels with notes and an introduction.
