17. Cradock.

18. Gr&iiff-Reinel. 



There is some cU)ubt as to the exact locahty o;f the Graaff- 

 Reinet s^)ring. In the Reix>rt of the (Government Analyst for 

 1906 it is described as being at Rynheath, but from enc|uiries it 

 would appear that the analytical data refer to a spring on the 

 adjoining estate Kruidfontein. According to local medical 

 opinion, these waters are anti-rheumatic and slightly laxative. 

 There is comfortable accommodation for patients, and a number 

 of bath-rooms have been erected in close proximity to the spring. 

 The spring issues from Lower or Middle Beaufort Beds. 



19. Lilani. 



These hot springs are about .seven miles south of Hermans- 

 burg, Natal, and the water issues from a fault line in crystalline 

 schists and metamorphic limestone There is a single spring, 

 and a gi"oup of four or five about 600 yards distant. At this 

 spot a well-a,ppointed sanatorium has been erected, at which a 

 ]:>hysician is in residence. Provision is made for open-air bath- 

 ing, and sand and mud baths are in the course of preparation. 

 The maximum temperature of the water is 39.5° C, the minimum 

 about 37°C. The water is re}X)rted to be radio-active, and is 

 claimed to be efificacious in cases of rheumatism, gout, sciatica, 

 cutaneous diseases, malaria and obesity. There is a feeble evolu- 

 tion of gas, containing a little sulphuretted hydrogen. Accord- 

 ing to the analysis the water contains sodium sulphite and 

 sodium thiosulphate.

20. Lochinvar. 



The water of the hot spring from the ranch L<jchinvar, 

 Magoye, Northern Rhodesia, contains a very considerable amount 

 both of sulphuretted hydrogen and of sodium sulphate. Accord- 

 ing to the report, it is likely to be of medicinal value, but I am 

 not aware of any tests having been made to establish its efficacy. 



21. Weltevreden. 

 The spring on the farm Weltevreden, Division Beaufort 

 West, rises from the Lower Beaufort Beds. It is suggested that
