168 NOTES. 
pedition was to investigate the extinct vertebrate fauna of the Tertiary 
and Cretaceous deposits of the Rocky Mountain country, and the general 
plan adopted was to make several separate trips, of one or two hundred 
miles north or south of the Pacific r aliroa d, to regions that were unex- 
plored, or had never been carefully exam ned. 
The first of these was made early in ped from Fort McPherson in 
Nebraska to explore the Pliocene deposits along the Loup Fork river. 
Here rich collections of fossil vertebrates were obtained, and several new 
— of extinct mammals and birds discovered. The next expedition 
made in August, from Fort D. A. Russell in Wyoming, to €— 
ien geology of the country between the north and south Magie: of t 
Platte river. Onthistrip the Mauvaises Terres or ** Bad land " Paire 
with the true Titanotherium and Oredon beds was discovered in Colorado, 
remains obtained were also PM and included several species of 
extinct mammals and birds, new to science. 
he third expedition was made DEN Fort Bridger, Wyoming, in Sep- 
tember and October, to examine the geology of the Eastern Uintah 
Mountains, and the country between the Green and White rivers. In 
this region interesting geological discoveries were made, and many new 
Tertiary vertebrate remains secured, which will soon i described by 
Professor Marsh. On their return, the party went to California, and 
spent a month in visiting various points of scientific interest; after which 
they came east to Denver, and thence to Fort Wallace, Kansas. Abou t 
two weeks were spent in exploring the Cretaceous beds of this vicinity, 
where some interesting reptilian and fish remains were obtained, and the 
party then returne 
The expedition as a whole was very successful, and the large collec- 
tions made will be placed in the Peabody Museum of Yale College. The 
more important scientific results will soon be published. 
apt. Wheeler, who explored in Nevada last year, has an expedition 
nén started or about to start. Mr. H. A. Green, late of the Illinois 
Geological Survey, is Geologist and Mineralogist. d Bischoff, 
who was an indefatigable member of the Scientific Corps the Western 
Union Telegraph Expedition, is to make the zoological police Capt. 
Wheeler is to ascend the Colorado Cafion from below with a steamer. 
His party will have abundant facilities for transportation, and the Com- 
mander is much interested in the scientific part of the work. Mr. P owell 
got an appropriation of $12,000 to make a second descent of the Cañon 
of the Colorado, and will do so some time this winter. He has alread 
been on to that part of the country, and arranged his details. Alto- 
gether the Cañon is in a fair way of being thoroughly explored. 
The French Académie des Sciences has held its sittings regularly since 
the beginning of the siege, and the Comptes rendus has been published 
regularly every week. — Nature.
