 hitherto been very slow to avail itself. 



The Museum of Hygiene 



The practical lessons thus given in the laboratory 

 are supplemented in an even more tangible manner, 

 because in a way more accessible to the public, in an- 

 other department of the institution which occupies a 

 contiguous building, and is known as the Museum of 

 Hygiene. This, unlike the other departments of the 

 institute, is open to the general public on certain days 

 of each week, and it offers a variety of exhibits of dis- 

 tinctly novel character and of high educational value. 

 The general character of the exhibits may be inferred 

 from the name, but perhaps the scope is even wider 

 than might be expected. In a word, it may be said 

 that scarcely anything having to do with practical 

 hygiene has been overlooked. Thus one finds here 

 numberless models of dwelling-houses, showing details 

 of lighting, heating, and ventilation ; models not merely 

 of individual dwellings, but also of school - buildings, 

 hospitals, asylums, and even prisons. Sometimes the 

 models represent merely ideal buildings, but more gen- 

 erally they reproduce in miniature actual habitations. 

 In the case of the public buildings, the model usually 

 includes not merely the structures themselves but the 

 surroundings lawns, drives, trees, out-buildings so 

 that one can get a very good idea of the more important 

 hospitals, asylums, and prisons of Germany by making 

 a tour of the Museum of Hygiene. Regarding the de- 

 tails of structure, one can actually gain a fuller knowl-
