1. Photograpli of the tongue taken frdni near Cam]) Station Ijy Hermann 

 W'oolley in igo2. Mt. Freshfield in distance. 





2. Tongue of glacier Irom nearly the same point as figure i. Photograph by 

 J. M. Thorington, 1922. 



Both photographs cover e-\actly the same field and are reproduced on exactly the 

 same scale. The greater apparent massiveness of the glacier in figure 1 is largely due 

 to the fact that it is upwards of 300 yards nearer to the camera. Its skyline therefore 

 conceals more of the distant mountains than does that of figure 2. The difference in 

 the aspect of the two is probably due as much to perspective as to the actual shrinkage 

 of the ice in the 20 years intervening.
