All this came from the study of a man who had an enormous experience, and if he had not gone on any further it would have been better. Lamarck’s views already stated may be accepted by everybody, and the grand changes in living forms under law are doubtless true. But he introduced the notion that “wants” exercised an influence and produced new organs, and wrote about effects of internal sentiment, and the influence of subtle fluids. Thus he argued that otters, beavers, waterfowl, turtles, and frogs, were not made web-footed in order that they might swim; but their wants having attracted them to the water in search of prey, they stretched out the toes of their feet to strike the water and move more rapidly along its surface. By the repeated stretching of their toes, the skin that united them at the base acquired the habit of extension, until, in the course of time, the broad membranes which now connect their extremities were formed. Lamarck taught that the first animals and plants which appeared on the globe were the simplest, and that the more complex are of comparatively late date. He insisted that nature was an order of things constituted by the Supreme Being, and subject to laws which are the expressions of His will. There is no doubt that these views of Lamarck were the result of many a pleasant hour of thought when things were dark enough around him. He was always poor, he married four times, had a large family, and a very small income. His genius led him to investigate other branches of natural science for which his education had not very well prepared him, and he got into disgrace with Napoleon for paying attention to meteorology. His patrimony and savings were lost in some wild speculation, and his thorough independence of thought and behaviour did not make him friends with the great and wealthy. His sight failed, and age grew apace, and he may be said to have simply existed for some years. Strangers and scientific men saw his state and poverty with surprise and regret; and their sympathy with Lamarck was redoubled when they observed the fortitude with which the illustrious old man supported the vicissitudes of fortune, and the failing of his natural powers. They also admired the devotion with which he had been able to inspire those of his children who remained under his roof. His eldest daughter consecrated her time to the duties of filial love for many years, never quitting her father for an instant, lending herself to every study which could in any way supply the defect of his vision, writing under his dictation part of his last works, accompanying him, and supporting him when he was able to take any exercise, and enduring sacrifices greater than could be expressed for his sake. When the father could no longer leave his chamber, the daughter no longer quitted the house. So long was she deprived of fresh air, that when she again faced the open breeze it was more than she could bear.
