mania, by Prof. Gregoire Stefanescu, of Bucharest, Roumania; The El:eo- 
lite-Syenite of Beemerville, New Jersey, by James F. Kemp; Notes on 
the Texas-New Mexican region, by Robt. T. Hill, an admirable paper 
describing: (1) the Lafayette formation of gravel, sand and silt, rang- 
‘ing in altitude up to 5,500 feet and averaging 200 feet in thickness, on 
‘the Llano Estacado, the Edwards Plateau, and the Washington Prairies, 
(2) Lafayette and Columbia fluvial and lacustrine beds, ranging together 
to thicknesses of 500 to 1,000 feet, in basins of western Texas and New 
Mexico, surrounded by faulted and tilted mountain blocks, and (3) vol- 
canic areas of eastern New Mexico, having lavas which overlie these late 
‘Tertiary and Pleistocene formations; The Relations of the American and 
European Echinoid Faunas, by J. W. Gregory, of the British Museum of 
Natural History, concluding that these continents have been so united at 
times during the Miocene and Pliocene periods as to permit their echin- 
-oid faunas, before widely different, to become closely related, in a man- 
ner “wholly incompatible with the theory of the permanence of the great 
ocean basins;” The Missouri Coal Measures and the Conditions of their 
Deposition (with a map and seven ideal sections in the text), by Arthur 
Winslow; The Pelvis of a Megalonyx and other bones from Big Bone 
Cave, Tennessee, by James M. Safford (see the Grouoaist, Oct., 1891, p. 
232); The Cienegas of southern California, by Eugene W. Hilgard, de- 
scribing alluvial fans of gravel, sand, and silt, which become reservoirs, 
with springs issuing on their lower portions and producing spots of ver- 
dure (cienegas) in otherwise arid tracts; The Chattahoochee Embayment, 
by Lawrence CU. Johnson, d-scribing Tertiary and Quaternary formations 
in western Florida; Peculiar geologic processes on the Channel Islands 
of California, by Lorenzo G. Yates; Inequality of Distribution of the 
Englacial Drift, by Warren Upham (see the GEoLoerst, Oct., 1891, p. 239); 
Effects of Drought and Winds on Alluvial Deposits in New England, by 
Homer T. Fuller (1. c., p. 239); and A Deep Boring in the Pleistocene 
near Akron, Ohio, by E. W. Claypole (1. c., p. 259). 
Three papers read at this meeting are printed in separate brochures, 
namely, Preliminary Notes on the discovery of a Vertebrate Fauna in 
Silurian (Ordovician) strata (pp. 153-172, with three plates, issued March 
15, 1892), by Charles D. Walcott, describing remains of placoderm fishes 
in Lower Trenton strata at Canyon City, Colorado; Certain extra-morainic 
Drift Phenomena of New Jersey (pp. 173-182), and On the northward and 
eastward extension of pre-Pleistocene Gravels of the Mississippi Basin 
(pp. 183-186), both by R. D. Salisbury, issued March 31, 1892 (see the 
GEOLOGIST, Oct., 1891, p. 238). 
The Labrador Coast: A journal of two suminer cruises to that region, with 
notes on its early discovery, on the Eskimo, on its Physical Geography, Geol- 
ogy, and Natural History. By ALeuEus SPRING PacKARD. pp. 513; with 
many maps and illustrations. (New York: N. D. C. Hodges, publisher, 
1891). This volume well presents nearly all that is known concerning 
‘the geography, geology, fauna (both of land and sea), and flora of Labra- 
‘dor. The author’s observations and discussion of the glacial phenom-
