The republic. [volume] (Washington [D.C.]) 1849-1853, 1850-05-10


not many years since, constituted the whole science
Of Geology. professor Of a college said, some
| thirty years ago, that when he took his place in
the institution teacher, he did not know that
there more than one kind of rock in the world,
and he did not know the name of that few years
after, this same professor wrote volume of some
six hundred pages ON rocks, and the various mine
raj treasures connected with them. This work was
translated into the German and French languages,
and was used a textbook by students in both
those nations. 1t also pronounced, by Eng
sh reviewers, as the best work extant on the sub
| ject.
Those attending the lectures of Professor Rogers
on Geology have heard described great variety
OF rocks, and each rock composed Of various mate
rails. Take granite as an example. The elements
OF granite quartz, felspar, and mica; but each
OF these is again composed Of several different ee-
ments, or ultimate principles Quartz is composed
of oxygen and silicium, commonly with portion
OF oxide of iron; that is, of two oxides of metals
The felspar is composed of three oxides Of metals
viz; scium, aluminium, and potassium, or slick,
alumina and potash; these combinations again
combined, in definite proportions, to form fespar.
Mica is still more complex in its combinations.
These three chemical compounds, of course in de-
finite proportions, by indefinite mechanical
able rock, widely used in all countries, for pur-
poses Of agriculture, architecture and many of the
useful arts. Two other rocks nearly allied 10 this
indeed formed by sediments of the same materials,
are gneiss and mica slate; both found in the form
of strata, while granite bears marks of crystaiza-
ton. Hence, ii appears that one rock takes three
distinctive forms, differing not much in the ma
terias of which they composed the arrange
ment of their materials These materials traced to
their chemical elements ultimate principles, are
found each to be exceedingly complex, though de-
] finite in its character
| Hence, a person, when once he finds that the
whole science of Geology is not embodied in the
| short sentence, 81 rock is rock finds
himself in the regions of chemistry; and to under
| stand one science he must learn another, and the
| two require various others. Yet, he advances,
each renders all the rest more simple, more rich,
and more intimately connected with all the wants
and all the comforts of human life.
Surely no who has the ability should fail to
attend the Smithsonian Lectures The fourth of the
course will be delivered might, at o'clock, and
will be repeated to- afternoon, at 81 O'Clock.
| Mrs. MApIsoN's Wilton Monday last, in the
circuit court the issue from the orphans court, in
the case OF Causten ct ux. Todd, was called to
the notice of the court by General Jones and j. b.
III. Smith, esq.,, counsel for the WILL and the court
was asked to proceed with the trial, as witnesses
were in attendance Mr. Carlisle, for the cavcator,
stated that his side there witnesses in
attendance; and suggested that Thursday be fixed
for the trial, which assented TO.
The accordingly called up yesterday,
when, after some consultation between coun-
sell Mr.. Carlisle addressed the court, and stated
that il had been agreed, should the court approve
thereof, to submit the points of law upon which is
sue had been joined to two members of the bar,
whose award will be rendered on before the 10th
instant. 1t was further requested that a jury
should. be retained pro lorna, in order that the de-
cison may be contaminated with full legal
ton and authority. The arrangement was acqui-
csccd in. James Nj. Carlisle, for plaintiff j. b.
/ II. Smith and p. r. Fendall, for defendants.
The TRAvERsE WILL CASE AGAIN.--At one
O'Clock, yesterday, the jury in this case after pass
ing three days and three nights in deberation,
4 came into court and announced that they un-
able to agree upon verdict; whereupon they were
discharged, and new trial ordered for the
next term. We understand there were six for set
ting aside the WILL and six opposed thereto; but
that nine of the jurors in favor of a compro-
mise, upon terms very liberal toward the plaintiffs
ADELPHI IHEATRE.-1he new comedy oil "Iht
Serious Family has been played nightly during
the past week, TO the manifest qualification Of large
audiences The play is keen satire upon the cant
and hypocrisy of the times and, though written
for the meridian Of London, its telling points are
equally applicable TO much that il visible at our
own doors. The piece introduced Mr.. Bradshaw
again upon the Adelphi boards, and he was re-
ceived with hearty welcome, as were also Mr..
and Mrs. Sloan their first appearance here.
Mrs. Sloan is an accomplished actress, and has
played several characters during the week with
marked success We learn that the new piece will
be Withdrawn for a time 10 give place 70 other
eties. Miss Julia Dean will appear during the en-
suing week.
