The e of the genitive is long after a vowel, as faciei, and common after a consonant, as fidei or fidei.

The genitive is sometimes contracted, as fidē.

ON THE PERFECT TENSES of the INDICATIVE MOOD.

67. The Perfect-Present represents an action as completed at the present time. Thus the Perfect-Present of Video, I see, which is Vidi, means I saw, or I have seen; and the words Romam vidi, may mean I saw Rome, on some occasion in time past, or I have seen Rome, which may mean, "at the time of speaking I have seen and still see Rome."

Here observe one of the defects of Latin, that it has but one tense to express the simple momentary act in time past—I came, and the completed act, of which the effects continue to the present time, I have come, both of which are expressed by Vēni.

68. The Perfect-Present of Active Verbs is formed in various ways, but always ends in i

1. By adding the syllable vi to the stem of the verb; which may be regarded as the regular formation in the First and Fourth Conjugations, as Amāvi, Audīvi.

2. By adding ui to the stem, as Colui, from Colo, I till;

or to the stem after the removal of a final vowel, as Secui, from Sěco, I cut; Monui, from Moneo, I advise. 3. By adding si to the stem, as Carpsi, from Carpo, I pluck. 4. By reduplication, that is, prefixing a syllable like that of the first syllable of the stem, as Cucurri, from Curro, I run- -the first vowel being often changed to e, as Fefelli, from Fallo, I deceive.

5. By modifying the stem without adding a syllable, as Egi, from Ago, I drive; Volvi, from Volvo, I roll. NOTE.-When, by the addition of si to the verb-stem, s is brought into contact with a consonant, changes are made of which the following are examples :

scribo has for its Perfect-Present scripsi.

69. The following is a list of some verbs in common use, to illustrate the various formations of the Perfect-Present.

The verbs to which D is prefixed take a dative to express the object favoured, hurt, etc.; thus, Faveo tibi, Noceo tibi.

70. Removing the suffix i we get the Perfect Stem, as amav-,

monu-, scrips-, vid-.

By adding to this stem the suffixes -ĕram, and -ěro, we form the Perfect-Past and Perfect-Future; thus

amaveram, I had loved (at some specified past time);

amavero, I shall have loved (at some specified future time). 71. These three Perfect Tenses are conjugated in the same way in all the conjugations; thus

NOTE 1.-In and Sub with the Accusative are much used with verbs of motion.

In and Sub with the Ablative are much used with verbs of rest.

NOTE 2.-The Preposition is often inserted between the noun and the adjective

Magno cum periculo, at great risk.
Multis de causis, for many reasons.

NOTE 3.-A genitive depending on a noun is often placed between the noun and the preposition that governs it; thusPompeium in amicorum numero habeo, I regard Pompeius as a friend.

73. The following are examples of the use of the Perfect in simple sentences:—

Hostium clamor milites terruit.
Caesar in Gallia bellum gessit.

Librum de Amicitia scripsit Cicero.
