When our ephemeris was first commenced, the corrections applied to existing tables rendered it more accurate than any other. Since that time, the introduction into foreign ephemerides of the improved tables of Le Verrier have rendered them, on the whole, rather more accurate than our own. In one direction, however, our ephemeris will hereafter be far ahead of all others.
After several days of discussion, it resolved that, beginning with 1901, a certain set of constants should be used in all the ephemerides, substantially the same as those I had worked out, but without certain ulterior, though practically unimportant, modifications which I had applied for the sake of symmetry.
Venette gives an instance of four testicles, and Scharff, in the Ephemerides, mentions five; Blasius mentions more than three testicles, and, without citing proof, Buffon admits the possibility of such occurrence and adds that such men are generally more vigorous. Russell mentions four, five, and even six testicles in one individual; all were not verified on dissection.
The first British publication of the sort, prepared by Maskelyne, Astronomer Royal, a century ago, was intended especially for the use of navigators; hence the familiar appellation, which I call unfortunate because it leads to the impression that the work is simply an enlargement and improvement of the household almanac. The leading nations publish ephemerides of this sort.
Cases of deficiency of the nipples have been reported by the Ephemerides, Lentilius, Severinus, and Werckardus. Complete absence of the hymen is very rare, if we may accept the statements of Devilliers, Tardieu, and Brouardel, as they have never seen an example in the numerous young girls they have examined from a medico-legal point of view.
Schenck has seen the left ventricle deficient, and the Ephemerides, Behr, and Kerckring speak of a single ventricle only in the heart. Riolan mentions a heart in which both ventricles were absent. Jurgens reported in Berlin, February 1, 1882, an autopsy on a child who had lived some days after birth, in which the left ventricle of the heart was found completely absent.
The Ephemerides, Haller, Schenck, and Archenholz cite examples, and there is an old account of a double-headed child, each of whose heads were baptized, one called Martha and the other Mary. One was of a gay and the other a sad visage, and both heads received nourishment; they only lived a couple of days.
The Ephemerides cites an instance of triple heart, and Johnston has seen a triple heart in a goose. The phenomenon of "blue-disease," or congenital cyanosis, is due to the patency of the foremen ovale, which, instead of closing at birth, persists sometimes to adult life.
Have you calculated the course of futurity? have you consulted your Ephemerides, your Almochoden, your Almuten?" "No, truly, counsellor," replied Mannering, "you are the only Ptolemy I intend to resort to upon the present occasion a second Prospero, I have broken my staff, and drowned my book far beyond plummet depth. But I have great news notwithstanding.
The reverse of the foregoing are those cases in which, by reason of the deficiency of the waters, the birth is dry. Numerous causes can be stated for such occurrences, and the reader is referred elsewhere for them, the subject being an old one. The Ephemerides speaks of it, and Rudolph discusses its occurrence exhaustively and tells of the difficulties of such a labor.
