INTERNATIONAL HYGIENE EXHIBITION

one can scarcely turn aside an ever-increasing impression of the exist- 

 ence of a great variety of distinct and widely differing species of the 

 genus homo. Even if a common origin for all should finally be accepted, 

 it will have to be admitted that the genus man has shared in the tend- 

 ency of all life in general, namely, that of producing varieties, differing 

 almost as widely from each other in their habits and productions as do 

 the various organs in a single individual living animal organism in their 

 functions. The study of the comparative physiology and psychology of 

 races (ethnology), therefore, teaches us that their respective manners, 

 customs and achievements differ in accordance with their hereditary 

 composition and will continue to do so to the end of time. 



About 450 individuals and firms had sent contributions to the his- 

 torical group of the exhibition alone. 



The German Workingmen's Insurance 

 The handsomely bound catalogue by Dr. Klein for the special exhi- 

 bition, intended to inform the visitor of the work accomplished by the 

 German workingmen's insurance, covering 107 pages, and filled with 

 but the briefest mention of the objects exhibited, will give an idea of 

 the wealth of the material found in Hall 10, presided over by Dr. jur. et 

 med. Kaufmann and Geh. Eat. Weger. The workingmen's insurance, 

 instituted in 1885 by Emperor Wilhelm I., pursues the object of pro- 

 tecting the workingmen against the unavoidable dangers of their call- 

 ing. Every working man and woman within the boundaries of Imperial 

 Germany is, regardless of nationality, legally insured against disease, 

 accident, invalidity and old age. The sums of money thus contributed 

 to the various workingmen's societies reach the limits of the incompre- 



Hall foe the Hygiene of Teanspohtation.
