S28 Professor Miiller on the Life and Writings of 



prosector and his colleagues Rudolphi was on the most friendly 

 terms. Every one must have remarked his respectful conduct 

 towards Knape, the colleague next him in the department of 

 anatomy. In the faculty and in the senate Rudolphi was dis- 

 tinguished in a remarkable degree for his participation in busi- 

 ness, and for the correctness and decision of his strongly ex- 

 pressed opinions ; and his valuable labours rendered important 

 and influential his situation in the scientific deputation of me- 

 dical aff'airs. 



In the year 1812, Rudolphi published his contributions to 

 anthropology and general natural history. The biography 

 there given of Pallas, and the essays on the arrangement of 

 animals according to the nervous system, — on the distribution 

 of organic bodies, — and on the relations of beauty in the two 

 sexes, are among the most attractive of his writings. In the 

 arrangement of animals, Rudolphi proceeded from the anato- 

 mical-physiological principle, and from that system of organs 

 which has most to do with imparting form to all the others, 

 viz. from the nervous system. The vertebrate animals with 

 the spinal system he termed Notoneura, also Diploneura^ on 

 account of the simultaneous occurrence of the spinal nervous 

 system, and the Nervus sympathicus. He named a second di- 

 vision Gasironeura or Myeloneura ; in these the nervous cord 

 lies in the stomach. In the third system he includes the ani- 

 mals with scattered ganglise ; and in the fourth those v/hose 

 nervous system is still unknown, which he terms Cryptoneura, 

 Although many invertebrate animals possess the system of 

 nerves of motion and sensation, and that of the organic nerves, 

 and although both systems of nerves may extend through the 

 whole animal world, yet the principle of arrangement is never- 

 theless striking, and exhibits to us in clearly marked differences 

 the chief subdivisions of animals, although not of those that are 

 the lowest in the scale. 



Rudolphi acquired the greatest reputation by his labours on 

 the natural history of intestinal worms. If the history of tlie 

 natural sciences were to dwell only on the names of discoverers, 

 those who had ascertained important facts from which many 

 others were explained, — who have disclosed a multitude of 

 forms, and the structure of entire classes of natural bodies, —
