The dative of indirect object is used with most Latin verbs 

 compounded with ad, ante, con, in, inter, ob, post, pre pro, 

 sub, and super, and sometimes circum ; the elements essential

 and Hindu roots, from which we learn that the people of 

 India, of whom only one man in ten, and only one w*oman in a 

 hundred are able to read and write, — from which we learn 

 that these people are our own cousins ; that many words still 

 live in India and in America that have witnessed the first sepa- 

 ration of the northern and the southern Aryans ; and, in the 

 words of Max Muller, "these are witnesses not to be shaken 

 by any cross examination. The terms for God, for house, for 

 father, mother, son, daughter, for dog and cow. for heart and 

 tears, for axe and tree, identical in all the Indo-European 

 idioms, are like the watch words of soldiers. We challenge the
