Lum Woodruff, An Early Meteorologist In Michigan And Texas, S. W. Geiser
Lum Woodruff, An Early Meteorologist In Michigan And Texas, S. W. Geiser
Field and Laboratory
The present fragmentary note on an early meteorologist in Texas is published in the hope that further information of Mr. Woodruff may be forthcoming. Fourteen years ago (Southwestern Historical Quarterly, 45, 284, 1942) I published a very brief note on Woodruff in the vain hope that the historians of Texas might be able to clear up the obscurities of his life; I hope that the present note, which goes to meteorologists and historians of science, may meet with a better fate. At least I shall have put on record what are the known facts regarding Mr. Lum Woodruff.

Nicholas Marcellus Hentz (1797-1856), Pioneer American Araneologist, S. W. Geiser
Field and Laboratory
An account the life of one of the least known among antebellum Southern naturalists. Nicholas Marcellus Hentz was, before his death a hundred years ago – he died 4 November, 1856 – the great American student of spiders. Through his numerous publications, including some 18 articles and a book, he gained wide acclaim as a naturalist.
William Lloyd, British-American Natural-History Collector In Texas, S. W. Geiser
William Lloyd, British-American Natural-History Collector In Texas, S. W. Geiser
Field and Laboratory
William Lloyd began his career as a collector and student of birds in western and southeastern Texas in 1880, after having come to Texas in 1876. For some time he lived in San Antonio (the information is fragmentary in many details), and in this period (1879) he first emerges as the discoverer of cement-rock near San Antonio, which resulted (1880) in the first cement manufactory west of the Mississippi River.

Notes On Mammals Of Dallas County, Texas, William B. Stallcup
Notes On Mammals Of Dallas County, Texas, William B. Stallcup
Field and Laboratory
Little is known of the distribution of mammals in north-central Texas. Russell's study of the mammals of Cooke County (1953) is, I believe, the only work of this sort which has been carried out in this area. During the last two years (summer of 1954 through the summer of 1956) my students and I have made regular collections of mammals from various stations in Dallas County, in an attempt to ascertain the species occurring and their relative abundance. This paper summarizes our results. It should not be considered a complete list for the county; doubtless species are present which we …
The Texas Species Of Limonium (Plumbaginaceae), Lloyd H. Shinners
The Texas Species Of Limonium (Plumbaginaceae), Lloyd H. Shinners
Field and Laboratory
Only two sea-lavenders occur in Texas, so that no great taxonomic problem exists so far as this area is concerned. One of the two, however, is a member of a difficult complex. It has passed under a number of different names, and has not been accurately described nor delimited in any publica-tions treating the genus. The following synopsis is based on 18 specimens (representing 17 collections) from Texas and 6 from Atlantic Coast states in the S.M.U. Herbarium, sup-plemented by descriptions of the eastern plants published by Blake, Fernald, Gray, and Small.
Andropogon Ischaemum L. Var. Songaricus Ruprecht: Technical Name For King Ranch Bluestem, Lloyd H. Shinners
Andropogon Ischaemum L. Var. Songaricus Ruprecht: Technical Name For King Ranch Bluestem, Lloyd H. Shinners
Field and Laboratory
In a previous paper (1954) I reported Andropogon Ischaemum as found wild in two Texas counties (Collin, Grayson), persisting after cultivation in one (Denton), and planted along open highway in another (Rockwall). Additional wild collections can now be reported from Brazoria, Brown, Dallas, Fannin, Kleberg, Live Oak, Mills, and Sutton counties. All are of plants with bearded nodes, and all the Texas records are therefore to be referred to Andropogon Ischaemum var. songaricus rather than to var. Ischaemum.

The Texas Species Of Dyssodia (Compositae), Marshall C. Johnston
The Texas Species Of Dyssodia (Compositae), Marshall C. Johnston
Field and Laboratory
I aim: (1) to distinguish by key the species of Dyssodia in Texas; (2) to map their Texas distribution as indicated by herbarium specimens; and (3) briefly, to indicate and discuss their relationships and nomenclature. Upwards of 2500 herbarium specimens have been examined. Many of these were not collected in Texas; this over-all survey threw much taxonomic light on, and indeed was prerequisite to an adequate understanding of, the Texas members of the group.

A New Species Of Tradescantia (Commelinaceae) From South Texas, Robert P. Celarier
A New Species Of Tradescantia (Commelinaceae) From South Texas, Robert P. Celarier
Field and Laboratory
This taxon first came to the attention of the author as the result of a collection of two plants from the Edwards Plateau by C. M. Rowell. Both of these plants died shortly after being transplanted, due to the long exposure they had received, but not before a few morphological notes had been taken. Later, in the spring of 1950, I encountered a small population in the Edwards Plateau of Texas between Burnet and Llano, along the roadside of State Highway 29 near Buchanan Dam. This was approximately fifty miles from the locality of the collection made by Rowell. The …
Determination Of Copper In Lead And Lead Base Alloys, Mcgee A. Duff, Charles T. Kenner
Determination Of Copper In Lead And Lead Base Alloys, Mcgee A. Duff, Charles T. Kenner
Field and Laboratory
This work was undertaken in an effort to develop a rapid method for the determination of copper in the range of 0.01 to 0.06% in lead alloys and in the range of 0.001 to 0.005% in lead. A visual and a photometric method are suggested, based on the color developed by copper in concentrated hydrochloric acid. Iron interferes with the determination, but this interference is reduced by use of an aluminum file in the visual method, and is corrected for in the photometric method by determination of the Lron as the thiocyanate. The visual method is very rapid, is accurate …

A Review Of Pertinent Literature On The Thyroid Of Urodela, With Special Reference To Necturus, Joseph P. Harris Jr.
A Review Of Pertinent Literature On The Thyroid Of Urodela, With Special Reference To Necturus, Joseph P. Harris Jr.
Field and Laboratory
The discovery by Gudernatsch (53) of the role of the thyroid in the control of metamorphosis in amphibia quickened interest in this field, with the result that an overwhelming number of papers has appeared since 1912 on the thyroid gland and its functions in amphibia and other cold-blooded vertebrates. Much of the literature has been reviewed elsewhere (75), and a complete analysis of all the publications will not be attempted here. The present review concerns, primarily, those papers dealing with the thyroid gland of Necturus; as also, secondarily, some papers treating of other animals, which were important in the development …
