300 Union Scientific Meeting at Dresden. 



concerning antelopes. Besides some beautiful notices by 

 Otto concerning several new facts in comparative anatomy, 

 Counsellor Seiler described his recent anatomical investiga- 

 tions ; Professor Munz of Landshut described the splanch- 

 nology composed by himself and illustrated with his own 

 lithographic drawings. Professor Husche of Jena, and in 

 particular the great master of comparative anatomy, Carus, 

 delivered an account of his grand discovery of the circulation 

 of the blood in insects : and many other anatomical and obste- 

 trical practitioners made communications which even the un- 

 initiated might listen to with profit and delight. 



Above all, the modern queen of sciences, chemistry, had 

 her fullest rights ; not only in the twofold essay delivered by 

 Professor Lampadius of Freiberg on the medicinal application 

 of carburet of sulphur; in the interesting information given by 

 Dr. Struve, on the composition of his mineral waters; in 

 Dr. Geitner's paper on the application of niccoliferous silver, 

 which is of such great importance to the manufacture of 

 pottery ; but also in important communications from Profes- 

 sors Munke, Purkinge, Scheigger, and Itunge, on the manner 

 in which quicksilver with brine and sulphate of copper stir- 

 red with a small iron rod, forms rotatory crystals and hastens 

 solution ; and in the interchange of ideas which was freely 

 indulged in by many other able men in their separate depart- 

 ments. 



A learned controversy arose respecting a dissertation by 

 Professor Wilbrand, of the first importance in regard to prac- 

 tical medicine, in which Professor Reich of Berlin with many 

 others expressed their doubts. Professor Rheum's lively 

 essay on the abuse and use of animal magnetism would have 

 called forth similar discussions if time had permitted. Dr. 

 Froxiess of Weimar made some important communications 

 respecting the situation of the fcetus. Many new productions 

 also, which yet were scarcely to be had at the booksellers', were 

 announced and distributed. Professor Weber's essay on the 

 production of the turf leech (blutegel uber torfboden: — hiru- 

 do stagnalis ?), which now fetches so great a price, had also its 

 turn. Many other Professors abridged their communications, 

 from the pressure of time. It is impossible here to do justice 

 to the various merits which were displayed on this occasion. 

 One disquisition in particular produced an effect on the au- 

 dience as extraordinary as it was agreeable, through the per- 

 spicuity of its style, and the singular felicity with which the 

 subject was illustrated by means only of a few simple lines 

 drawn on the table : this was by Dr. Oken, on the form of 

 the fcetus from the time of conception and the first germ of 



life,
