Contributions

Wagner's activity as a writer and worker was enormous, and his range extensive, most of his hard work having been done at Erlangen while his health was good. His graduation thesis was on the progress of the working classes. The ambitious title of The historical development of epidemic and contagious diseases all over the world, with the laws of their diffusion showed the influence of Schönlein.

His first treatise was Die Naturgeschichte des Menschen (in 2 vols, Kempten, 1831). Frequent journeys to the Mediterranean, the Adriatic, and the North Sea gave him abundant materials for research on invertebrate anatomy and physiology, which he communicated first to the Munich academy of sciences, and republished in his Beiträge zur vergleichenden Physiologie des Elutes (Leipzig, 1832–1833, with additions in 1838). In 1834-1835 he brought out a text-book on the subject he chaired (Lehrbuch der vergleichenden Anatomie, Leipzig), which recommended itself to students by its clear and concise style. A new edition of it appeared in 1843 under the title of Lehrbuch der Zootontie, of which only the vertebrate section was corrected by himself.

The precision of his earlier work is evidenced by his Micrometric Measurements of the Elementary Parts of Man and Animals (Leipzig, 1834). His zoological labours may be said to conclude with the atlas Icones zootomicae (Leipzig, 1841). In 1835 he communicated to the Munich academy of sciences his researches on the physiology of generation and development, including the famous discovery of the germinal vesicle of the human ovum
Ovum

.

These were republished under the title Prodromus historiae generationis hominis atque animalium (Leipzig, 1836). As in zoology, his original researches in physiology were followed by a students' text-book, Lehrbuch der speciellen Physiologie (Leipzig, 1838), which soon reached a third edition, and was translated into French

In 1843, after his removal to Göttingen, he began his great Handwörterbuch der Physiologie mit Rücksicht auf physiologische Pathologie123.13.24, and brought out the fifth (supplementary) volume in 1852. His only original contributions to this work were on the sympathetic nerve, nerve-ganglia and nerve-endings, and he modestly disclaimed all merit except as being the organizer. While resident in Italy for his health from 1845 to 1847, he occupied himself with research on the electrical organ of the torpedo genus of electric eels

 believer. This lost him the respect of a number of his old friends and pupils, and was unfeelingly told that he was "suffering from an atrophy of the brain." His quarrel with Carl Vogt and other materialists began with his oration at the Göttingen meeting of the Naturforscher-Versammlung in 1854, on "Menschenschöpfung und Seelensubstanz." This was followed by a series of "Physiological Letters" in the Allgemeine Zeitung, by an essay on "Glauben and Wissen," and by the most important piece of this series, "Der Kampf um die Seele vom Standpunkt der Wissenschaft" (Göttingen, 1857).

Having come to the consideration of these philosophical problems late in life, he was at some disadvantage; but he endeavoured to join as he best could in the current of contemporary German thought. He had an exact knowledge of classical German writings, especially of Goethe
