THE POPULAR SCIENCE MONTHLY 



Hall for Army, Navy and Colonial Hygiene. 



ancient framers of the laws already knew the great value to the state of 

 strong and healthy people as shown by the laws they promulgated. 

 Food adulterations also received their due share of attention. But the 

 most significant hygienic characteristic of ancient Eome and Greece 

 centers undoubtedly in the methods of street construction, water supply 

 systems and sewerage systems. 



Another special room is devoted to showing the efforts of the phy- 

 sicians of those ancient times as being not alone those of restoring the 

 sick to health, but also those of preventing the well from becoming sick. 

 A plan of the sanatorium in Kos shows its sanitary situation on the 

 south side of a hill covered with trees. Mothers were made to nurse

 year of their lives. 



The last room of classical antiquity is devoted to burial customs. 

 It is here shown that cremation was not the exclusive method of dis-

We shall have to pass over the different epochs that mark the prog-

 ingly emphasized by a great variety of exhibits, collected from all parts 

 of the world and contributed at great expense, distributed through 22 

 rooms, both large and small, and in which that gradual but steady pro- 

 gress was shown by graphic, plastic and pictorial exhibits from the time 

 when physicians diagnosed disease by simply looking at the urine-bottle 

 of their patients, up to the period when hygiene began to be taken more 

 seriously and entered into the dignified domain of an experimental 

 science. 



We must, likewise, pass over the ethnological portions of the exhibi- 

 tion, although most interesting and highly instructive in showing the 

 customs and habits of the different races peopling our globe and their 

 common desire for a long, happy and healthy life. 



In leaving the historical and ethnological groups of the exhibition,
