an entry sur disseisin in the per, and upon 
an entry where the first disseisor has en- 
feoffed another, and he a third, it is an en- 
try sin' disseisin in le per et eni. An entry 
in le post states only that the tenant hath 
not entry bnt after (post) the disseisin of 
A. B. which is allowed in cases beyond the 
foregoing degrees. There are other writs 
adapted to particular cases, which we shall 
only mention by name, and refer to the 
larger dictionaries of the law for their pre- 
cise meaning : such are 
Entry ad communem legem, for the re- 
versioner of tenants in dower by courtesy 
for life, &c. 
Entry ad terminum qui prater lit, a writ 
for the reversioner after the end of a term 
or estate for life, against a stranger in pos- 
session. 
Entry in casu consimili. 
Entry in casu proviso. 
Entry causa matrimonii preelocuti. 
Several points of law occur, as to ,the ef- 
fect of an entry in the case of joint tenancy 
and coparcenary ; of entry by the heir ; of 
entry to divest an estate ; to take advan- 
tage of a condition which cannot be investi- 
gated here ; but in general it may be ob- 
served, that a bare entry, without expul- 
sion, makes only a seisin ; so that the law 
thereupon adjudges him in possession who 
has the right. 
ENVELOPE, in fortification, a work of 
earth, sometimes in form of a simple para- 
pet, and at others, like a small rampart 
with a parapet : it is raised sometimes on 
the ditch, and sometimes beyond it. 
ENVOY, a person deputed to negotiate 
some affair with any foreign prince or state. 
Those sent from the courts of France, Bri- 
tain, Spain, &c. to any petty prince or 
state, such as the princes of Germany, the 
republics of Venice, Genoa, &c. go in qua- 
lity of envoys, not embassadors ; and such 
a character only do those persons bear, 
who go from any of the principal courts of 
Europe to another, when the affair they go 
upon is not very solemn or important. 
There are envoys ordinary and extraordi- 
nary, as well as embassadors ; they are 
equally the same under the protection of 
the law of nations, and enjoy all the privi- 
leges of embassadors, only differing from 
them in this, that the same ceremonies are 
not performed to them. 
ENURE, in law, to take place or effect, 
or be available, as a release made to a te- 
nant for a term of life, shall enure to him in 
the reversion. 
EPA 
EPACRIS, in botany, a genus of the 
Pentandria Monogynia class and order. 
Calyx five-parted ; corolla funnel-form, vil- 
lous ; nectariferous scales growing to the 
germ ; capsule five-celled, five-valved ; the 
partitions front the middle of the valves; 
seeds minute and numerous. There are 
four species, natives of New Zealand. 
EPACT, a number arising from the ex- 
cess of the common solar year above the 
lunar, whereby the age of the moon may be 
found out every year. See Chronology. 
The excess of the solar year above the lunar 
is 11 days ; or the epact of any year expres- 
ses the number of days from the last new 
moon of the old year, which was the begin- 
ning of the present lunar year to the first of 
January. The first year of the cycle of the 
moon, the epact is 0, because the lunar 
year begins with the solar. On the second, 
the lunar year has begun 11 days before the 
solar year, therefore the epact is 11. On 
the third, it has begun twice 11 before the 
solar year, therefore the epact is 22. On 
the fourth, it begins three times 11 days 
sooner than the solar year, the epact would 
therefore be 33 ; but 30 days being a syno- 
dical month, must that year be intercalated ; 
or that year must be reckoned to consist of 
thirteen synodical months, and there re- 
mains three, which is the true epact of the 
year ; and so on to the end of the cycle, 
adding 11 to the epact of the last year, and 
always rejecting 30, gives the epact of the 
present year. Thus to adjust the lunar 
year to the solar through the whole of 19 
years, 12 of them must consist of 12 syno- 
dical months each, and 7 of 13, by adding a 
month of 30 days to every year when the 
epact would exceed 30, and a month of 29 
days to the last year of the cycle, which 
makes in all 209 days, i. e. 19 XU; so 
that the intercalary or embolimaean years 
in this cycle are 4, 7,10, 12, 15, 18,19. 
If the new moons returned exactly at the 
same time after the expiration of nineteen 
years, as the council of Nice supposed they 
would do (when they fixed the rule for the 
observation of Easter, and marked the new 
moons in the calendar for each year of the 
lunar cycle) then the golden number multi- 
plied by 11, would always give the epact. 
But in a Julian century, the new moons an- 
ticipate, or happen earlier than that council 
imagined they would by £ of a day. In 
a Gregorian common century, which is one 
day shorter than a Julian century, they 
happen ^ of a day later, (1 day — £ — \\).
