Interesting rs WIS tho main part OF Prof.
benjamin Pcirces lecture at the Lowott lpst!-
tute Last evening, there was ono part which will
command nt once the attention Of the scicnt!Rc
world, both from the h.gh reputation Of tho
lecturer unll from the facts he enyo to support
Ills views. lIe broaehed tho theory that around
tho cptlre solar system is a spllcticai she'll of
tnntter, from Which fall the nlctepFs which sun-
ply tho heat Of the sun, mud 10 which return the
comets anl metcors which bass around the sun.
Th!s theory, Prof, relrct stated, has not set
been propounied to tho scientific world but
wilt be soon, Below will be found the chief
points Of the lecture:
The final stage OF the nebular history Is the
planet It, may be- considered under th. hea,1s
Of conEcalc1 star, Inorganic pcrtotl, organic pe-
riod, planet. satellite, comet, meteor, iiud cha
ottc mass. Through tho process Of conIensu-

The perfect comet combines nucleus anil train.
The beauty belongs to the train, wlch Ia unsub-

density reside in the almost Invisible but per-
mnnent nucleus. The solid nucleus moves about
the sun In nearly paraboIic orbit, obetlicnt to
the same law Of attraction which governs The
motions Of either Of thc planets; whereas pnch
