Descriptive Sociology. He tells me, to my surprise, that 

 all my books have now been translated into Russian with

 soon be added to the list. Further he tells me that he has 

 proposed to the Historical Society of Kiev to make a like 

 classification and tabulation of Russian history. The name 

 of this Russian is Lontchitzice.

MY DEAR SPENCER : Your father's little work on In- 

 ventional Geometry is now in the hands of the printers, 

 and we shall bring out a neat edition of it in the form of 

 Macmillan's Science Primers, of which Hooker furnished 

 the last, on Botany. I propose to include the Inventional

 effect, or saying whatever you wish about it, I shall be very 

 glad, as they will be valuable in drawing the attention of 

 teachers to the book and to the method it illustrates.

 Dr. Vetter as soon as the Biology is out of hand, and he
