THE following is an account of a research which was pursued at the Marine Laboratory of the Carnegie Institution at Tortugas, Florida. An interesting jellyfish, Cassiopea xamachana, lives upon the muddy bottoms of the lagoons of coral islands in the Florida and West Indian regions.
A BIOGRAPHICAL HISTORY OF BOTANY AT ST. LOUIS, MISSOURI
LABORATORY OF FOREST PATHOLOGY, BUREAU OF PLANT INDUSTRY, U. S. DEPARTMENT OF AGRICULTURE
DR. PERLEY SPAULDING
THE history of botany in St. Louis extends back nearly to the beginning of her political history. The city was founded in 1764, and while it is not as old. as most of the other large cities of this country it seems to have been one of the earliest settlements made in the great northwestern region, comprising what was once known as Upper Louisiana.
THIRTY years ago in this very city I heard for the first time a presidential address at the British Association, and I was singularly fortunate in entering on my novitiate. I had the privilege of hearing Professor Huxley deliver his presidential address to the embryo of that section over which I, a very unworthy successor, have this day the honor to preside.
FOR twenty years the Canadian government has been carrying on experiments in wheat growing under the supervision of the director of the Experimental Farm at Ottawa, Dr. William Saunders. The United States leads the world in the production of wheat; Canada's growth is only one ninth as large, her export to Great Britain during the years 1901-3 was slightly less than one fifth, though in 1905 it was somewhat more than one half.
IN war between nations the standardization of armies is universally recognized to be the first essential of efficiency. The function of every leader, every fighter and every carrier is distinctly understood. Likewise in the domestic war of commerce, which is chronic, the organization of great corporations, with division of labor and singling of industrial functions, is the greatest promoter of both production and distribution.
DURING the latter part of August, last year, the International Zoological Congress met at Boston. This circumstance was not very widely heralded by the press, nor did it make an impression on the public mind at all comparable to that ordinarily produced by any serious crime.
WHAT little I shall say is about personal loyalty. It is due myself that I should explain that the greater part of this address was written more than two years ago, and especially for my own students, who frequently have to meet certain ethical problems in connection with their professional work.
THE discovery of X-rays was announced by Professor Röntgen in December, 1895, in a communication to the Physico-medical Association of Würzburg. The date of the discovery is commonly thought to be November, 1895. As a matter of fact, the first X-ray photograph was made about two years before that time, and the accidental production of this photograph was the starting point of a series of investigations which continued for more than two years before the public announcement was made.
A GREAT PERMIAN DELTA AND ITS VERTEBRATE LIFE, WITH RESTORATIONS BY THE AUTHOR
DR. E. C. CASE
AS early as 1878 it was known that the remains of a wonderful group of animals lay hid in the rocks of north central Texas, that had lived their appointed time and passed away before the earth history was half completed; since then collectors have gone into this region more or less regularly, contending in the early days with hostile Indians and later with bad water and difficult transportation.
THE development of the American university during the last quarter of the nineteenth century is perhaps the most important chapter in our recent history. In this remarkable movement two institutions have led, and their prominence is personified in two great ( educational leaders, President Eliot, of Harvard, and President Gilman, of the Johns Hopkins.
