diprothetic composition. Those prepositions hold their color 

 longest which play the most prominent role in diprothetics and 

 triprothetics. Thus, dvri appears as first element in 27. eVt in 39, 

 iin' in 50, TT/ao in 35, and Trpos in 17 diprothetics, while of tripro- 

 thetics, dvTi has 5, and '^vv, Trpd, Trpos and viro, have each one. The 

 absence of eVi in triprothetics would seem to militate against this 

 view, but coincident with this absence, it occurs as a second 

 element in S out of the g triprothetics in Thuc\'dides, reinforced by 

 dvTL in 5 out of the 8 cases and by -n-poi in one, thus indicating the 

 fading out of the color of iirl in diprothetics. 



This tendency to make that combination in which there will be 

 the most strength, shows itself also in another way. In the forma- 

 tion of a diprothetic, when there exists a choice between mono- 

 prothetics in €k or airo, or between ets and Trpos, or between Kara 

 and ai'Tt, the forms in ck, ei's .md Kira are chosen. The exceptions 

 can usually be explained. Thus, dyw (see Table II.) has ck 

 instead of aTro as second element in diprothetics; e?p.t, €k 3 times, 

 aTTo once; ep^ofXH, ck instead of aVd,- laTiyxt does not count, as other 

 considerations are involved, such as loss of color of kxto. and the 

 military character of a<^io-TrjixL, accounting for the preponderance of 

 these elements here. In this phenomenon we are limited to the 

 class of diprothetics which represent the plastic side. Naturally 

 enough, those simples predominate here in which the motion is 

 least obscured. Where modification is necessary, room and mo- 

 bility are needed. It follows that the second elements of dipro- 

 thetics represent two opposite conditions of things: ist, loss of 

 color of the preposition; 2nd, vividness of preposition. In the 

 first case, reinforcement was aimed at; in the second, modification 

 of the idea of the verb. Hence there is greater diprothetic feeling 

 in the latter class than in the former, and from this follows the 

 comparative ease with which diprothetics of the former class were 

 formed and their consequent preponderance over the latter class. 



In triprothetics, the principle of reinforcement again is chiefly 

 operative, and here naturally enough, the second element is the 

 least conscious. It is noticeable that ctti is second element in 8 of 

 the 9 triprothetics in Thucydides. 



i^iiniiiiary. 



In the foregoing discussion I have endeavored to prove the 

 theorem for Thucydides: 



In general the range of combinable prepositions of a verb is in direct 

 ratio to the nearness with which the verb expresses pure motion.
