Remarkable for the venose and vesciculose frond, and for the very 
long and slender terrete jointless elaters. The veins of the frond 
anastomise and divide its substance up into large cavities. Rootlets 
numerous, long, granulose. Capsule about as large as in A. /aenis, 
slightly curved or straightish; the valves more or less twisted 
when dry, without stomata. Spores about half as large as in A. punc- 
tatus, and the elaters many times longer than in that species, and of 
a different structure. Involucre of a solid texture.

86. Dr. Torrey and Torrey’s Peak.—As some misapprehension 
_ exists as to Dr. Torrey’s ascent of the peak named in his honor, we 
made inquiry of Mr. John H. Redfield, whose reply we give belew. 
_A note from Miss M. Torrey is to the same effect. 
“Twas not with Dr. Torrey on the occasion of the ascent to 
which you refer, having parted company with him in California in 
the end of August [1872]. But soon after his return home I had 
from him, and from his daughter who accompanied him, the full 
_ particulars of the affair; and as I had myself ascended Gray’s Peak 
on the 30th July previous, the topography was sufficiently known 
to me to make their account quite intelligible. Their party, con- 
sisting of the Doctor and his daughter, and a Norwegian lady, 
related to Prof. Brock, of N orway, with a physician from Georgetown, 
whose name I have forgotten, and perhaps some others, started from 
Georgetown, for the purpose of ascending Gray’s Peak. It was late in 
the season for the ascent,* and some of their friends in Georgetown 
counselled them not to attempt it. They proceeded, however, with- 
out any difficulty until they reached the shanty near the Baker 
Mine—a height of nearly or quite 12,000 feet, and on a plantation in 
full view of the two rocky cones named by Dr. Parry, Zorrey’s Peak 
and Gray’s Peak. By this time the weather had become very 
cold, the wind also being keen and strong. The rarity of the alr, 
too, at that height, told so severel y upon the Doctor’s respiration, 
that he found it impracticable to proceed further. He accordingly 
entered the shanty, built a fire, and had a warm lunch ready tor 
the rest of the party, who, meanwhile, proceeded on horseback, 
and succeeded in reaching the summit of Gray’s Peak. By the 
_ time they had returned to the shanty rain set in, which soon 
_ became snow; and Jong before they reached Georgetown all the 
neighboring mountains were covered with a fleecy mantle. mA 
“So that though the Doctor did not literally ascend Torrey 8 
Peak, yet he saw both it and its fitly: named fellow-peak.t+ 
* Late in September. . weal. 
+ Gray’s expression in his Memoir is—“Stood upon the flank of the snowy 
_ peak to which his pupil had given his (Torrey’s) name;” which, in asense 
_ 38 true, since both peaks are culminating points of the same ridge on which, 
_ Baker’s Mine is situated.
