ing to the character and direction of the energies employed. 
The pLanet, on which we live, is a spheroid, whose shortest 
diameter is at the same time its axis of rotation and the direc- 
tion of greatest attraction. As far as we have been able to as- 
certain, the same conditions prevail on all the planetary bodies 
of our system. The analogy between planets and molecules 
is not a mere superficial one/ and reasoning from all the data 
in our possession, we cannot be far wrong if we look upon a 
free molecule as a rotating spheroid, with a north and south 
pole, and an equatorial region where gravity is, in some meas- 
ure, counterbalanced by centrifugal force.

THE BRENHAM, KIOWA COUNTY, KANSAS, METEORITES 
By N. H. Winchell and Jajies A. Dodge, Minneapolis.

We are indebted to Prof. Robert Hay for information re- 
specting the finding of this group of meteorites, and for assis- 
tance in procuring two of them. The entire group, so far as 
ascertained, numbered at least fifteen. They were dis- 
covered some years ago (1885) when the prairie of that part of 
the state was first plowed for cultivation, but the ranchmen 
and farmers simply regarded them with idle curiosity as 
"heavy stones." The high prairie and a sand-hill region, are 
totally destitute of stones of every kind. Only in the ravines 
is there a show of transported gravel. Some eff'ort was made 
by some parties to attract the attention of scientists to them, 
but without success. Only lately has their true character 
been discovered. Several of them were at once purchased by 
Prof. F. W. Cragin, of Washburn College, Topeka, and by Prof. 
F. H. Snow of the Kansas State University, Lawrence. Two 
were purchased, at second hand, and are now at the Universi- 
ty of Minnesota ; four of the specimens of Prof. Cragin have 
subsequently been purchased by Mr. George F. Kunz, of New 
York, his collection weighing over nine hundred pounds. They 
vary in size from four pomnds to four hundred and sixty-six 
pounds. The largest specimen is owned by Mr. Kunz, one of the 
smallest weighing six pounds, being one of those examined by
