BIBLIOGRAPHY, A STUDY OF RESOURCES. l6l 



M tiller remained the editor from 1833 to 1858. He was one 

 of the greatest scientific men Germany has produced, and ranks 

 as pioneer and founder of three sciences : of comparative anat- 

 omy and embryology, or, as we now prefer to say, morphol- 

 ogy, of experimental physiology, and of scientific pathology. 

 He was endowed with that genius for observation and induction 

 which alone enables a man to become a great leader in natural 

 science. In the first volume of his Archiv he gives a " Jahres- 

 bericht ueber die Fortschritte der Anatomischen-physiolo- 

 gischen Wissenschaften im Jahre 1833." Since that time, 

 Germany has supplied us our most important annual records 

 or summaries. The Jahresberichte of Johannes Muller are 

 most interesting reading, even to-day ; they are remarkable for 

 the clearness with which the important points are brought to 

 notice. In later years he engaged various collaborators in this 

 work, among whom we find Siebold, Keferstein, Reichert, and 

 others. With Mtiller's death, in 1858, these reports closed. 



Their place was taken by two series of Reports, one issued 

 in connection with the Archiv fur Naturgeschichte, the other in 

 connection with the Zeitschrift filr Rationelle Medizin. The 

 former journal was founded in 1835 by Professor Wiegmann, 

 of Berlin, and originally published with each Heft a report of 

 progress in some field of zoology or botany ; with its second 

 year it began the system followed up to the present time, of 

 issuing two volumes a year, the second made up entirely of 

 reports for various branches of biology. Of late years the 

 Archiv fur Naturgeschichte has shown a predominant entomo- 

 logical tendency, both in its original articles and reports, 

 although it still continues to cover a wide range, except that 

 botany has entirely dropped out. Its reports are often very 

 late in appearing, and are irregularly issued ; thus the part 

 published in November, 1894, gives the reports on entomology 

 for 1893, on carcinology for 1891, 1892, and 1893. In spite of 

 all these peculiarities you will find these Berichte often valuable. 



The Zeitschrift filr Rationelle Medizin was a first-class scien- 

 tific serial. It entered upon its third series in 1857, and then 

 began issuing, as an annual volume, a "besondere Abtheilung" 

 the first of which bears this title : " Berichtiiber die Fortschrittc
