From this the reader will be able to judge what extraordinary difficulty there was in the Scotch to an English reader of those days. The use of z instead of y, of y instead of th, are matters very easily mastered; and it is surely the utmost folly to suppose that Queen Elizabeth could have found the slightest difficulty in deciphering this northern version of the common tongue. The document quoted above is a very powerful and no doubt also violent assault upon the Hamiltons, especially called forth by the murder of the Regent Murray, the slackness of the succeeding Government in the punishment of his assassin, and the powerful reasons there were for destroying--a measure which Buchanan thought imperative both for the safety of the realm and the child-king--that powerful family, the head of which was next in succession to the Scotch Crown, and had been popularly believed to be ready for any crime to obtain it. Now that there was nothing but the life of a child between the Hamiltons and this elevation, Buchanan lifted up his testimony against the supineness which left the race undisturbed to carry out its evil designs. Murray had been murdered in the beginning of 1570, and the _Admonition_ was printed at Stirling a few months later. In the same year Buchanan wrote that curious tract called the _Chameleon_, a satirical attack upon Lethington, which is not very brilliant either in language or conception, and fails altogether in the incisive bitterness which characterises most of Buchanan's other political papers. "It is at least equal in vigour and elegance to that of most compositions in the ancient Scottish language," says Buchanan's biographer, but few modern readers will agree in this verdict. Buchanan's hand had not the lightness necessary for such a performance. The guilt of Mary and the death of Murray furnished him with more emphatic motives than the iniquities of Maitland, and he was evidently stronger in assault and invective than in the lighter methods of composition.
