Grand sympahetc nerve and their precise seat Is III
the nervous lanents which accompany the arteries;
their material phenomena consisting III tie dllataion

genuine attack Of intense headache, the patient suf-
fcrs everywhere the hands are swollen the muscles

studies on the subject, ~ dc Chfgan concludes that
any treatment for headache should be directed
against affections of the nervous system, especially
Of the great sympathetic, and against the arter a,
dataton which results, and constitutes the essential
feature of the malady and that IN this. there are
| three points to bs considered: tho intermlttence,
| the pain and the arterial dlataLion. Ills SPECIAL

circtIulsi ancos, stS iii the administration OF

TIE GREAT CouEr or lGsi-The investigation
of the great comet of 1854 forms the subject of the
| inanpural dissertation of Prof. Neugebauer of the
University of Br Sian. This comet belongs 10 those
| which on account Of the close approximation of
their orbits to the earhs orbit have attracted the
attention Of Prof. Schapare M worthy Of scrutiny
in connection with shooting stars. The only accu-
rate observations Of the comet OF 1854 that have
come down to were made during two weeks at
Rome by Bianclini; and in order to derive from
these the best possible results, Neugebaner has re-
dueed them all anew, by using the best materials
available he having access TO original letters and
drawings $, i'll in existence. The observations made
bV Bauciui of the simp IT kind for instance,
he would hold stretched thread III such position
that lille covered some knownone Of the fixed lars
it nearly covered the comet tselt, whose position
relatively TO tie ends Of TIE thread, was then esl-
mated by the eye Other and more exact obSer'a-
lions were made with the hep of rude Instruments.
Tie relative positions of the comet as dcduccd by
great labor to be-, in general, trns worthy 70
within "a few minutes of arc, and Neugcbaucr's ele-
nents of It's orbit not greatly different from those
gwen by Haley Ii follows, as the most interesting
result of the investigation that on the 18th of Jne,
1854, the distance of the comet from the earth was
only the hundrcth part of the distance of the earh
from the sun, being, in fact ONLY tie triieth part
of the distance of the earth from Coggias comet
the 2lst of last July, when it was nearest the earth.
Ii seems therefore, that the orbit of the comet Of
1851 approaches more nearly 10 the orbit of the
earth tIan almost any other known comet and that
under favorable circumstances We shall be iuste
in expecting some meteoric display yearly about The
IS.h of jane at which time tie earth annually
comes into the plane of this comets orbit.
| RELATION BETWEEN THE MODERN AND TERTIARY
! FLORAs-A communication was made to the Vienna
Academy by Ettingshausen, embodyng his extensive
researches tertiary plant-fossis and their study
in connection with modern Goras. Regarding the
present vegetable world as the result of a former
preparatory condition, he proceeds upon the fact
that the modern fioras already prciqrcd in the
tertiary fora, not confined. however, at present,
to different distinct regions, but that plants, Mt
present denizens of widely different portions of the
earth then ilourshcd in the same region The state
