Cardan lived an abstemious life. He broke his fast on bread-and-water and a few grapes. He sometimes dined off bread, the yolk of an egg, and a little wine, and would take for supper a mess of beetroot and rice and a chicory salad. The catalogue of his favourite dishes seems to exhaust every known edible, and it will suffice to remark that he was specially inclined to sound and well-stewed wild boar, the wings of young cockerels and the livers of pullets, oysters, mussels, fresh-water crayfish because his mother ate greedily thereof when she was pregnant with him; but of all dishes he rates the best a carp from three pounds weight to seven, taken from a good feeding-ground. He praises all sweet fruit, oil, olives, and finds in rue an antidote to poison. Ten o'clock was his hour for going to bed, and he allowed himself eight hours' sleep. When wakeful he would walk about the room and repeat the multiplication table. As a further remedy for sleeplessness he would reduce his food by half, and would anoint his thighs, the soles of his feet, the neck, the elbows, the carpal bones, the temples, the jugulars, the region of the heart and of the liver, and the upper lip with ointment of poplars, or the fat of bear, or the oil of water-lilies. These few extracts will show that an intelligible narrative could scarcely be produced by the methods Cardan used. The book is a collection of facts, classified as a scientific writer would arrange the sections and subsections of his subject. In gathering together and grouping the leading points of his life, a method somewhat similar to his own will suffice, but there will be no need to descend to a subdivision so minute as his own. A task of this sort is never an easy one, and in this instance the difficulties are increased by the diffuse and complicated nature of the subject matter; and because, owing to Cardan's wayward mental habit, there is no saying in what corner of the ten large folios which contain his writings some pregnant and characteristic sentence, picturing effectively some aspect of his nature or perhaps exhibiting the man at a glance, may not be hidden away.
