MIR. Jacob Ennis of Philadelphia has recently
preseI:ed discussion oftle ncbuar theory
lie first attacks the problem Of thecauoe OF tue revelation
Of nebula II is admitted that 10 ali portions OF nebuia
were OF equal density. its condensation would SIMPLY re-
suit in a spherical mass without rotation Ga the "hef
hand II there were inequality in tic density OF tic
masses composing il, and in their distances from the
common center these In their fall toward that center
gond have their motion translated INTO cpticu paths
like those Of comets. Manifestly ths would give
speed Of rotation to the outer portions OF the
nebula taken 5 Al whole. which would only De par
TALLY and 10y slow degrees communicated to the central
mass Some the results Obtained IN WORKING OUT 'lo
mathematics involved in this theory may prove OF inter
est fan the orbit OF Neptune to that Of Uranus
should add "a speed the nebuous ring from which the
latter was formed OF d miles per second THIS amount
added To the actual velocity Of Neptune. should give
Uranus a velocity of nearly 4A miles per second The
sctual velocity OF Uranus 1863 The difference in this
and similar cases Mr. nus aScrbes to the loss Of speed
caused by the friction between The sio"-mO'mS
interior and the switmoying exterior masses
o the whole solar Hcbula. This retardauon
would be greater with approach to the center oil the
