54^ THE MEDICINAL SPRINGS OF SOUTH AFRICA. 



water and the air in contact with it are strongly radio-active, and 

 the water is said to retain its radio-activity for a considera])le 

 period after botthng. The total yield of all the springs is 

 180.000 gallons per day. There is a well-appointed hotel and 

 sanatorium. Provision is made for ordinary and electric mas- 

 sage and for electric baths. The visiting physician is in atten- 

 dance at the sanatorium daily. In addition to the ordinary bath- 

 rooms a large swimming-bath has been erected. In 1897 Dr. 

 C. W. B. Daniell wrote a brochure dealing with the therapeutic 

 ])roperties of the Caledon waters, and in 1908 Dr. W. Darley 

 Hartley contributed a paper to the South African Medical Con- 

 gress* containing, iiifcr alia, a discussion of the effects produced 

 bv the treatment with the water. All information about the 

 history of the springs, the equipment of the sanatorium, etc., is 

 contained in an illustrated pamphlet issued by the company own- 

 ing the baths, and obtainable on api)lication.
