134 PHYSICAL INVESTIGATION. [PART I. 



August to the whites. 1 Brehm however denies the different 

 effects of seasons upon different races in East Sudan. 2 



Though, according to the above statements, it is scarcely 

 probable, as asserted by Werne, 3 that Negro soldiers are less 

 able to bear the fatigue of a campaign in hot countries than the 

 white, it is not less certain that Negroes cannot without diffi- 

 culty support a cold climate. The Negro is sensitive to even 

 moderate changes of temperature. 4 Callie and other travellers 

 relate that on such occasions they complain bitterly of cold ; 

 we must, however, bear in mind the scanty covering which they 

 use. This must also be taken into consideration when Richard- 

 son 5 mentions that the Negroes seem not so well to support the 

 hot winds in Sahara as the Arabs and the Moors, in addition to 

 the fact, that in North Africa the change of temperature is 

 sometimes very great, being on some occasions so low, that 

 French soldiers have been frozen to death. The Kaffirs, who 

 were some years since exhibited in Europe, did not show any of 

 that sensitiveness to cold which the real Negro is said to possess. 

 This sensitiveness is, however, not exclusively peculiar to the 

 Negro ; the Bisharis have the same peculiarity, 6 and the in- 

 habitants of Fezzan, habituated to a high temperature, are 

 accustomed, in inquiring about each other's health, to say, 

 ' ' I trust you don't feel cold/' 7 A great susceptibility of change 

 of temperature is a usual consequence of residence under the 

 tropics, and is not confined to the Negro. 8 The Negro is said to 

 become insane in cold climates; this, however, is not unfrequently 

 the result of his being transported to other countries. Selberg 9 

 found among the Ashantee Negroes imported into Java, several 

 suffering from insanity. In the New England states of North 

 America, the Negroes, it is said, would become extinct were it
