remaining kinds have been perhaps rather recklessly used by vivisectors, whose ardour in the noble cause of science has caused them to experiment, on an average, on about 14,000 dogs apiece (an example originally set by the sainted Maurizio Schiff), and the result has been that we only find at present twelve animals surviving, of whom nine belong to the class Mongrel. One noble old Newfoundland, who would have greatly graced the collection, was, it is said, drowned by his owner last year under interesting circumstances. The dog was much devoted to his master (a celebrated physiologist), and especially to his boy, a child of six years old. One day the little fellow fell out of a boat, and sank for the last time, when the dog arrived, and with immense difficulty (the water being very deep and stormy) dived for him and brought him safe to shore. The animal itself was so nearly exhausted that its stertorous breathing and other symptoms suggested to the physiologist the scientific interest which would attach to watching it slowly drowning in a suitable vessel, where all the conditions of that death could be accurately investigated on so large a scale as that of a full sized dog. The learned gentleman accordingly, in obedience to these fine and fleeting suggestions of the intellect, drowned the animal in a tub in his physiological laboratory as soon as his son was sufficiently recovered to witness the instructive and entertaining spectacle. The dog, when withdrawn half dead for a moment from the water, having attempted to lick the boy’s face, the child was weak enough to implore his father to spare it; but the learned gentleman of course pointed out to the boy the folly of such a request, and the experiment was completed. We trust to see this young gentleman hereafter as sound and eminent a physiologist as his distinguished father. After some five columns more of similar _Intelligence_, the _Age of Science_ proceeds to give its readers a few Reviews of Books. The brevity of the remarks vouchsafed to these productions seems to indicate that no great importance is attached to Literature properly so called, but only to treatises on Physical Science. The Notices run as follow:— _REVIEWS._
