fouud at Keokuk above the geode bed, aud represented by No. V6 ol' the 
section. This conclusion had been announced previously in a paper be- 
fore the Iowa Academy of Scien«e (Mar. 10, 1890).* Mr. Beachler has ar- 
rived at the same results independently from a study of the Indiana 
area. 
Those studies tfnd to aseparation of beds iiitherto considered identical 
though much additional work is needed to set at rest obvious (pies- 
tions. 
The disposition of the chert or transition bed below and the Magnesian 
or Warsaw above is still an open question, though recent writers seem to 
favor Owen and Hall in including them with the Keokuk. The evidence 
seems to sustain the following arrangement, here given tentatively: 
Keokik. Indiana. 
f Magnesian or 
I Wartsaw beds. - - Spurgeon Hill lieds. 
I Blue Sandy bed. - Craw fordsville beds.

Chert bed. - - New Hoss beds. 
This follows very closely Owen's division, made in 1852. In a paper 
on the Mississippian Section (Lower Carboniferous) before the G. S. A., 
('. R. Keyes has given a brief descri tion of the Keokuk group, in 
which he ignores the work of previous observers, and gives but an im- 
perfect exposition of this important group of rocks.

W. M. Harvey. — Another quiet aud earnest worker in the tield has 
been called to rest. Mr. W. M. Harvey, of Glen Rose, Texas, was buried 
on the 12th iust. To most of the readers of this journal his name was 
unknown. He belonged to none of the scientific societies, aud held no 
scientific position, yet he lived a life devoted to nature, and through liis 
e.xploralions, made in the intervals of leisure he was able to take from 
his occupation as a house carpenter, discovered important material, now 
in the hands of Prof. L. F. Ward, of the U. S. Geological Survey, and 
Prof. E. D. Cope, of most signal value in completing the determination 
of the great lower Cretaceous system of this country. Throiigli his 
patience as a collector, many important results were secured, in the 
vicinity of Glen Rose, including a locality where marine mollusca of the 
Trinity formation, as figured in th°i Arkansas reports, were associated 
with the Potomac flora of the north Atlantic states, and above all, with 
tlie first determinable fossil vertebrates from those beds, including croc- 
odile and fish remains. This discovery is important because, with the 
three fold evidence it affords, the age of the lowest fossil bearing beds 
of the Comanche series can now be fix«»d with certainty. Professor
