Reserve University. 
Harrington’s most elaborate paper on ‘The 
Calciferous Glands of the Earthworm, with 
Appendix on the Circulation ’ was in press at 
the time of his death, and had been accepted 
asa thesis for the degree of Doctor in Philos- 
ophy, which he had hoped soon to receive 
from Columbia University. An important 
paper on Amceba and its reaction to the 
stimulus of light waves of different inten- 
sities, written in collaboration with Mr. 
Leaming, was published during the past 
summer. The following briefer articles 
testify to his energy and enthusiasm as a 
field naturalist; ‘Observations on the 
Plankton of Puget Sound’ with the col- 
laboration of his ever devoted friend, the 
late Professor Peck ; ‘ Notes on the distri- 
bution and habits of some Puget Sound 
Invertebrates,’ and on ‘ Nereids commen- 
sal with Hermit Crabs.’ 
All who knew Harrington will agree 
that his character, courage and earnestness 
in the pursuit of knowledge, which led to 
the sacrifice of his life are well worthy of 
permanent record. His sympathetic and 
generous mind, his capacity for friendship, 
his industry and zeal are endowments 
which any young man would be fortunate 
to possess. He has left an honorable name 
in zoology, more lasting than the simple 
cross which now casts its shadow on his 
grave.

Part I. of this volume, by Professor Haworth, 
is a general description of the Kansas Coal 
Measures, which the author divides into Upper 
and Lower, embracing seven formations with 
twenty-five subordinate divisions. Some of the

latter will be subdivided in turn when further 
studies have been made. The total thickness. 
is not far from 3,000 feet. 
The Lower Coal Measures include the Chero- 
kee and Marmaton formations. The Cherokee, 
400 to 500 feet thick, consists mostly of shales 
but contains some irregular limestones and some 
sandstone beds of economic interest. The coal 
beds are important, being those mined at Pitts- 
burg, Fort Scott and Columbus, and are avail- 
able in an area of about 12,000 square miles. 
The Cherokee covers a wide space in Indian 
Territory, extends into Iowa to form part of 
the Des Moines formation, and Professor Ha- 
worth is inclined to think that the important 
coal fields of Arkansas may belong to the same- 
horizon. 
The Marmaton consists of alternating lime- 
stones and shales. The lower and middle lime- 
stones, Oswego and Pawnee, are persistent, but 
the intervening Labette shales are irregular in: 
distribution. The upper limestone, the Alta- 
ment, is thin and not persistent, so that the 
Pleasanton shales, divided at some localities by 
the limestone, are unbroken over a large area. 
The lower division of the Oswego limestone is. 
the well-known Fort Scott cement rock <A 
few coal beds occur in the Marmaton, but thus 
far they seem to be unimportant. 
The remaining five formations belong to the 
Upper Coal Measures as grouped by Professor 
Haworth. 
The Pottawatomie consists of three lime- 
stones, Erie, Iola and Garnett, separated by 
the Thayer and Lane shales. The Erie lime- 
stones, having a maximum thickness of 225. 
feet, are usually triple with intervening shales, 
which thicken southwardly at the expense of 
the limestones until the latter become insignifi- 
cant. The upper limestone is cherty and all 
are very fossiliferous. The Thayer shales have 
an extreme thickness of 200 feet but thin north- 
ward, so that the Iola limestone, which thickens. 
in that direction to 200 feet, is at length prac- 
tically continuous with the upper Erie. The 
Lane shales and Garnett limestones are some- 
what irregular in their variations, but the lat- 
ter, owing to erosion of the overlying shales, is 
exposed over a great area. This formation 
contains no coal of economic importance.
