(1912)
“ With wide reading in all branches of standard literature, but especially historical and political, and with a retentive memory, Watson combined a rare power of coordinating what he knew. The characteristics of decision and determination which his features suggested were quite overborne by his gentleness and benevolence. Reserved and retiring to an unusual degree, he yet in social converse put his stores of wit and learning at the free disposal of his guests. Throughout his life he was a convinced liberal, and a considerable force in Oxford politics. ”
