undoubtedly infect the water with the specific germs of those diseases. 
Ordinary colds and sore throats following the plunge bath are frequently 
laid to the effects of the bath, while in most cases such results are un- 
doubtedly due to germ infection. One of the factors which lead the writer 
to take up this subject was an epidemic of colds among the users of the 
Purdue swimming pool this fall. 
Venereal diseases could be transmitted through the agency of the 
swimming pool. One case of gonorrhoea could infect many eyes in a 
crowded swimming pool. 
It is practically impossible to compel the bathers to submit to a com- 
plete medical inspection and physical examination before they are allowed 
to enter the pool, and yet from many points of view this would be a most 
desirable thing. 
The least that can be done for the protection of the bathers is to in-

All persons must take a soap shower before entering the 
pool. 
All persons using the pool musTr wear bathing suits or 
trunks. 
Of course facilities must be provided for the required showers, and 
each person should provide his own towel and soap. 
In the Central Baths, Bradford, England, special arrangements are 
provided for washing the feet.’ a most desirable thing as a prerequisite 
to the use of the pool. (See Fig. 7.) 
PRACTICAL PURIFICATION OF WATER IN SWIMMING POOLS. 
The amount and character of the pollution in swimming pool waters 
point very clearly to the need of some practical process of purification. In 
most cases it is too expensive to have a continuous change of water, and
