528 LETTERS TO DARWIN AND OTHERS. [1865, 



Nearly all the little I possess is cheerfully put into

 that, in a quiet way, make the French emperor very 

 uncomfortable in Mexico ; but we hope that country 

 may yet be a strong power, but not a French power. 



Enough of politics ! And believe me to be, with 

 affectionate regard, Ever yours, As A GRAY.

 evening read over Heer's address. It is, as you say, 

 capital. It interests me in its proof of the antiquity 

 of the present flora ; and I admit that he very neatly 

 puts the case between his view of the production of 

 our species out of the older ones, and that of Darwin. 

 Here it still rests : Darwin has the great advantage of
