the scope of his culture, pursued philosophical studies, and finally settled upon the organic sciences. His interest was gradually diverted from mathematics, and he took up zoölogy with enthusiasm. Johann Müller—whose portrait, his son Erich Schmidt says, in the memorial address from which we draw most of the facts of his life, always adorned his room—permitted him, in 1845, after a summer term in comparative anatomy at Heligoland, to take part in a research upon sea animals, and impressed a stamp on the young investigator's view of Nature that lasted till the Darwinian revolution. Christian Gottfried Ehrenberg interested him in the investigation of the minute life of the infusoria, and, besides being his teacher, had a fatherly affection for him.
In 1846 Schmidt obtained a promotion to Doctor of Philosophy at Halle, the subject of his still unpriuted dissertation being the sacred Scarabæus. He passed the higher teachers' examination in Berlin, and thereby avoided a year of probation at a realgymnasium. In August, 1847, he habilitated himself at Jena. He presented, on the occasion, a paper entitled Morphological Fragments, in which, while the name of Oken was mentioned appreciatively in the introduction, the gap between his philosophy and the current zoölogy was insisted upon. He became Professor Extraordinary of Natural History in this university in 1849, and Director of the Grand Ducal Zoölogical Museum in 1854. While at Jena he published the Handbook of Comparative Anatomy (1849), the Hand Atlas of Comparative Anatomy (1852), and a historical study on the Development of Comparative Anatomy (1855). Some results of a journey to the North in the course of his studies of the Turbellaria were embodied in a lecture on the Faroe Islands (1848), and Pictures from the North, collected during a Journey to the North Cape (1854), a versatile work, in which his sharp powers of observation were well illustrated. A work of somewhat different character was a lecture on Goethe's Relation to the Organic Natural Sciences, which was delivered in the Berlin Singakademie and was printed in 1853.
Having occupied the professorship at Jena for seven years on a salary never exceeding one hundred thalers, and after declining an invitation to Prague, Schmidt in 1855 accepted the appointment of Professor of Zoölogy in the University of Cracow. The conditions at this institution were quite different from those which had surrounded him at Jena. He received more liberal allowances than had been granted him there; but political affairs were disturbed, and he withdrew in 1857 to become Professor of Zoölogy and Comparative Anatomy, and eventually rector, at Grätz. Here he spent the fifteen most enjoyable and most fruitful years of his
