Edward Moorhouse, Dictionary of National Biography… (1912)
“ Of medium height, and possessed of an iron will, Day was a model man of business. Like his father, who, on Sunday evenings, used to read Blair's sermons to the stable lads until they fell asleep, he was most punctilious in the discharge of his religious duties. For his patrons he won stakes to the value of over 200,000l. At one time a comparatively rich man, he lost the bulk of his fortune by speculating in poor land. ”
