On The Trigonometric Developments Of Certain Doubly Periodic Functions Of The Second Kind, M. A. Basoco Aug 1932

On The Trigonometric Developments Of Certain Doubly Periodic Functions Of The Second Kind, M. A. Basoco

Department of Mathematics: Faculty Publications

The class of meromorphic functions which satisfy periodicity relations of the form (1) ƒ(z + 2ωl) = c1f(z), f(z + 2ω2) = c2f{z), where the multipliers c1 and c2 are independent of z, and ωl2 is a complex number with non-vanishing imaginary part, has been named by Hermite doubly periodic of the second kind. It is possible to make the study of these functions depend on others of the same type, but such that one of the multipliers, say cl, is unity. In what follows …


The Practical Evaluation Of Resultants, T. A. Pierce Mar 1932

The Practical Evaluation Of Resultants, T. A. Pierce

Department of Mathematics: Faculty Publications

The purpose of the present note is to give a practical method of evaluating the resultant of two equations. The method is particularly effective when the degree of one of the equations is high while that of the other is low. Use will be made of certain results in the theory of matrices.


The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour Jan 1932

The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Platybelodon barnumbrowni was described originally as Torynobelodon barnumbrowni.1 The Nebraska State Museum was visited and this unique specimen studied by Dr. Henry Fairfield Osborn and Dr. Walter Granger, August seventeenth and eighteenth, nineteen hundred and thirty-two. It is the opinion of both that this specimen belongs properly to their Mongolian genus Platybelodon. With certain reservations the writer wishes to defer instantly to their judgment, which is based on unequalled experience. It is perfectly apparent that this form makes a close approach to the remarkable Platybelodons found by Granger and Andrews in the Gobi Desert of Mongolia, later figured and …


A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

A slab of pale, reddish-brown sandstone, exhibiting the articulated skeletons of two oreodonts, has been placed on display in the west corridor on the first floor of Morrill Hall. Apparently, a female and well-grown young one lay down together and perished, perhaps from disease, or from chilling winds. They must have been buried quickly, for all of the bones are present, are in perfect condition, and are in articulation, especially in the old one. In the adult the articulation is complete from the ungual phalanges of the two forefeet to the terminal caudal, even though in the figure the skeleton …


The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

A composite skeleton of Bison occidentalis was mounted and installed in its case on the lower floor of Morrill Hall, on April 22, 1932. The skeleton in itself is attractive because of its size and excellent preservation, and is rendered additionally interesting by two dart-points, one found under the scapula, and the other under the ribs.


The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The association of artifacts with extinct bison bones in a quarry near Grand Island, Hall County Nebraska,1 and from one in Custer County, Nebraska, have already been reported.2 In the meantime, continued search has been rewarded, and a large bed of fossil bison with associated flint implements found. The discovery, if not of actual consequence, at least adds something to the accumulating evidence that Pleistocene man in America may have been a reality.


Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz Jan 1932

Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz

Bulletin of the University of Nebraska State Museum

During the past four years the Nebraska State Museum, under the directorship of Dr. Erwin Hinckley Barbour, has been making even more extensive palaeontological collections throughout Nebraska than heretofore. As work progresses, especially with fossil bison and mammoth, there is increasing evidence that man appeared in Nebraska much earlier than is generally believed. Two occurrences of artifacts associated with fossil bones will constitute the main theme of this paper.


The Skull And Mandible Of Mastodon Moodiei, Erwin Hinckley Barbour Jan 1932

The Skull And Mandible Of Mastodon Moodiei, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The mandible of the Milford mastodon, Mastodon moodiei, was figured and described in Bulletin 24, December, 1931. In the meantime, the fragments of both skull and mandible have been properly cleaned, put together, and mounted for exhibition. No essential parts of the skull or mandible are wanting or are seriously damaged.


The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour Jan 1932

The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The mounted sketleton of Eubelodon morrilli was installed in the west wall case of Elephant Hall December 31, 1931, and has attracted the attention and favorable comments of citizens and other guests. It should be explained that the case in which it is displayed is ten feet deep, sixteen feet high, and extends the length of the hall. Altogether it is a large and impressive mount which reflects credit upon its preparators, and is an important and instructive addition to the Morrill Palaeontological Collections. The pose is spirited and interesting, and the action is all that can be expected of …


Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour Jan 1932

Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Of late, anthropological literature relative to the association of man and extinct mammals, especially bison and mammoth, has received many contributions from various and widely separated sources. Naturally the question has arisen whether man's advent in America is somewhat earlier than has been generally admitted, or whether certain extinct animals have persisted longer than has been realized. The issue is one of such importance and interest that even minor contributions seem desirable. It is well understood by all that the evidence, when submitted, will be properly weighed, and that conservative judges may rule out much or all of the testimony. …
