CORRESPONDENCE 285 



think that your readers have a right to expect such contributors 

 not only to say that they disagree, but also to give the reasons 

 for their point of view. I take it that all your readers are deeply 

 immersed in some field or other of scientific work, and that 

 Science Progress usefully and successfully enables us all to 

 obtain a reasonably broad knowledge of the general trend of 

 scientific work. As regards the Ice Age, it is clear that there 

 we have a subject of very considerable interest to all of us, and 

 my friends and myself look forward with much interest to the 

 matter being further discussed. 



Yours faithfully, 



W. H. Hatfield.
