Among the important items of his business, and according to popular repute one of the most profitable, was the issue of weekly papers, which, the outer pages being left blank for local news, were circulated under various titles throughout the United Kingdom. But the greatest venture of the firm was undoubtedly the _Family Bible_, which was commenced in 1859. The cost of production is said to have amounted to £100,000; in six years upwards of 350,000 copies were sold, and it is at present calculated that half a million have been disposed of. Of the influence of this and other kindred works in displacing the infamous prints and penny serial horrors, the _Bookseller_ says--“We recently took a survey of the shop-windows in the notorious locality known as the Seven Dials. Here in one street, were three shops, the windows of which were filled with really respectable publications. In one shop scarcely anything was displayed but _Cassell’s Family Bible_. In every one, of at least twenty-four, figured some event of sacred history. On making inquiries we found that a very large number in the very poorest neighbourhood was taking in the work every week, and expressed their delight to possess a long coveted article of furniture in the shape of a _family Bible_.” Up to his death Cassell was true to his early resolutions of fostering the progress of temperance and education, and on these subjects he was a frequent and popular lecturer. He took also a lively interest in the business of the firm, but latterly the management was virtually in the hands of his partners. The “History of Julius Cæsar,” by the ex-emperor, was, however, entrusted to his care, and was the last publication in which he took an active interest. On the 1st of April, 1865, he died at his residence in Regent’s Park. He is described as having “a fine, massive, muscular frame, active and temperate habits of life, a cheerful disposition, a well-regulated mind, and troops of friends.” Rising from the ranks, he was by his industry able to leave his wife a shareholder in one of our largest book-manufacturing firms to the extent of, it is said, forty-two thousand pounds. The main interest of his life must, however, be considered to lie in the earnestness with which he laboured in causes he felt worthy of all labour, rather than in his career as a publisher, for the books he issued were little other than reprints of books whose popularity had been previously tested.
