"The idea Of increasing the adhesiveness Of the wheels Of
locomotives without Increasing their weight has Tor num-
Der Of past occupied the attention Of mechanicans In
the researches OF which have the honor TO present the re
suits to the Academy, have employed purely physical
agent (eecto to produce the adhesiveness The
idea Of this application originated with M Nicklss II was
ELECTED by MN. Ambergcr and Cassal, who consulted MI
Nckes the aid which the physical sciences might be
able to furnish for the solution Of this problem Of adhesion
The first experiment which made with this view mmedi-
aely demonstrated the possibility Of his application, and soon

competent 10 whatever connected with railways en-

have in these experiments established results to which

WHILE tho contrary magnetic sdhesveness Is always the

pertubaions figs &C., which considerably impair adhe-
produced by weight, do sensby affect magnetic adhe-

require greater force of traction than one OF which the wheels

The galvanic battery which serves to magnetize the
wheels may be utilized in any other ways while the train IS
moving For instance, it may be made to work break or
stop, (ectroein,) vetabe electromagnetic which has
the break stop in the advantage Of setting
exclusively apsn the rails while the others direct their whole
power upon the wheels essenng the apdiy OF their rola
ton, and sometimes entirely stopping them From this re-

immediate consequence the disadvantage Of rendering them

The memo from which the above is taken concludes with
an indication Of the manner in which electro magnetism may
be employed as motive power.

The Legislative Assembly enters on the 2sth
linstant next Wednesday, upon its third year.
From that day, by the terms Of the Constitution,
propositions for its total or partial amendment may
be legally made. The political Parliamentary Clubs,
which are nothing more or less than permanent
caucuses held by Representatives in the Assembly,
members of the various parties, have had numer-
GUS meetings Of late, and have determined to make
of revision test question, not between the more or
less LIBERAL the more or less honest, the more or
less monarchcal mode of administering the Republic,
but radically expressly, and calling things by their
proper names, between Monarchy and the Rep,tb.

des Pyramides, (Orleano- Bonapartists,) the most
numerous, that Of the rue de RiUoi, (pure Legiti.
MIST and that Of the rue de rUniUersifie, Mole.

ing general terms the revision Of the Constitution
They are to make separate but similar propositions
which each party for itself will support by argu-
ments based upon its particular view of the exi-
gencies OF the situation, the direction of its own
reactonist tendency. The Bonapartsts or Impe-
rialists con6ne themselves for the present to ask
ing the legal partial revision. Of the Constitution,
trusting, no doubt to good luck, good management,
and the aid afforded BY partial revision, to enable
them, when the time and place shall arrive, to put
