Geology and Paleontology. 635 
upon the summit of the Guadalupe mountains occur masses of 
shell-rock (masses lavignes) impregnated with siliceous lime- 
stone, which demonstrates their contemporary origin. What hin- 
ders me from believing that the existing hydrothermal springs at 
the foot of the Pefion can be the origin of the formation which 
surrounds the mountain is that these springs form only isolated 
and insignificant deposits, which cannot spread out uniformly 
like those of which Professor Newherry speaks, and which are 
characteristic of geysers. The above-mentioned springs were 
probably the last traces of the abundant eruptions of calcareo- 
siliceous waters which formerly shot forth at the same time with 
veins, or of the alteration of the basalts of the mountain. We 
must, therefore, believe in the importance of the discovery of the 
man of the Peñon. 
No-one can be more anxious than I to base these discoveries | 
Upon clear and well-determined facts, as I stated in my arti- 
cle in the Naturauist. Professor Castillo and myself 
have assiduously studied the Pefion formations, and with the 
sincerity which scientific truth exacts we will inform the learned 
World of later discoveries. If it should happen that in the rocky . 
omb of the man of the Peñon the remains of his primitive 
Weapons or the iron of his conqueror should be found, we shall 
doubtless be the first to announce it—Mariano Barcena. 
< JON THE Fossir FLORA OF THE LARAMIE SERIES OF WESTERN 
Canana. — The Laramie series, formerly known as the Lignite Ter- 
tiary or Lignitic group, occurs-in Canada, principally in two large 
areas west of the tooth meridian and east of the Rocky moun- © 
tains, and stretching northward from the United States boundary. . 
c “se areas are separated from each other by a low anticlinal of | 
retaceous beds, over which the Laramie may have extended 
Previously to the later denudation of the region. 
Ri areas may be designated—(1) The Eastern or Souris 
al ver and Wood Mountain area ; (2) the Western area, extending 
“ong the eastern side of the Rocky mountains and across the 
pper „Waters of the Bow, Red Deer, Battle and North Saskatche- 
wan rivers, 
In the southern part of the district of Alberta it has been 
been _ Possible to divide the Laramie into three parts, which have
