 of dolomite rhombs had first been suspected, as a result of analyses 

 made of that portion of the marly sediments which was soluble in 

 dilute acid. The rhombs were isolated by methods indicated by 

 Dr. Cullis, and compared with his specimens ; but the method of 

 identification now described by him was not adopted. He was 

 glad to hear of the distances to which salt was carried by the 

 wind in Iiajputana, since there was some indication of much the 

 same phenomenon in the part of Egypt now described. Eoraminifera 

 were also carried to great distances, as in India ; and the Author 

 was surprised to find unbroken foraminifera in sands filling the 

 gullies high up in the mountains. He agreed with Dr. Evans as 

 to the important part played by wind in erosion. The planing-down 

 effect of the wind was especially well seen on the islands in the 

 Red Sea.
