The fact that seolian calcareous rocks are not more frequently 

 recorded from the sedimentary rocks is easily explained. In the 

 first place, like all terrestrial deposits, they are not favourably 

 situated for preservation. If the land is sinking, they are liable to 

 be destroyed by wave-action as the sea advances ; while, if the land 

 is rising or stationary, they are exposed to the destructive action of 

 subaerial agents, to which they are especially susceptible. The 

 almost complete absence in temperate regions of recent deposits of 

 this description, and consequent want of familiarity among geologists 

 with their characteristics, may, in some cases, have prevented their 

 recognition. A careful examination of the limestone-rocks in the 

 light of the eeolian deposits that have been described from so many 

 parts of the world, may lead to the identification of still further 

 examples dating from a more or less remote past.
