First appearance of this paper in which Phillips summarizes his importen work on the moons surface."In 1852 John Phillips brought maturee geological experience to his own personal observations of the physiocal features ofthe surface of the moon, using first the great telescope belonging to the Earl of Rosse...The drawings (of surfaces of the moon) were to be made under a set of standard conditions of representation and on a uniform scale...By 1853 he was recording his observations photographically on collodion palets and employing his great artuistic skill in accurate and detailled drawings...In a summary of his findings published in 1868 (the paper offered), Phillips drew vivid analogies between many of the features seen on the surfaceof the moon and those known to him intimately by observation and measurement on the earth."(DSB X, p. 584.).

(Paris, Gauthier-Villars), 1880. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome 91, No 18. Pp.(698-) 736. (Entire issue offered). Bell's paper: pp. 726-727. First printing of the paper in which Bell speculates how his and Tainter's invention of the Photophone or Radiophone could have a wider use. He pondered the photophone's possible scientific use in the spectral analysis of artificial light sources, stars and sunspots. He later also speculated on its possible future applications, though he did not anticipate either the laser or fiber-optic telecommunications:"Can Imagination picture what the future of this invention is to be!.... We may talk by light to any visible distance without any conduction wire.... In general science, discoveries will be make by the Photophone that are undreamed of just now." Not long after its invention laboratories within the Bell System continued to improve the photophone in the hope that it could supplement or replace expensive conventional telephone lines. Its earliest non-experimental use came with military communication systems during World War I and II, its key advantage being that its light-based transmissions could not be intercepted by the enemy.

On the basis of this theory a number of conclusions can be drawn." (From the introduction to the present paper).

He discovered that hydrogen is present in the sun's atmosphere, and he was the first to examine the spectrum of the aurora borealis.

Stamp to front free end paper. Otherwise a fine and clean copy. Pp. 315-327. [Entire volume: IV, 398 pp.]. First printing of Fermi's paper on the impact between atoms and electrically charged particles.In statistical mechanics he had written subtle papers on the ergodic hypothesis and on quantum theory. Here he had developed an original form of analyzing collisions of charged particles. He developed the field produced by the charged particle by the Fourier integral and used the information from optical processes to determine the result of the collision. This method was later refined and better justified on the basis of quantum mechanics and is generally known as the Weizsäcker-Williams method.

Berlin, Julius Springer, 1923. 8vo. In contemporary half cloth with gilt lettering. In "Zeitschrift für Physik" Bd. 20, 1923. Entire issue offered. Stamp to front free end paper, otherwise a fine and clean copy. Pp. 237-255. [Entire volume: V, (1) 426 pp.]. First appearance of Bothe's early paper on the Compton effect which, together with his later paper (in Bd 32, Zeitschrift für Physik), awarded him the Nobel Prize in Physics "for the coincidence method and his discoveries made therewith"."Among the topics that Bothe studied in 1924 was the ejection of electrons by X rays, and it was in connection with this phenomenon that he and Geiger performed an important experiment. In an effort to reconcile the particulate and wavelike properties of radiation, Bohr, Kramers, and Slater in 1924 formulated a new quantum theory of radiation. According to their hypothesis, momentum and energy-are conserved only statistically in interactions between radiation and matter. Bothe and Geiger suggested that this could be tested experimentally by examining individual Compton collisions. Bothe introduced a modification into the Geiger counter that made it appropriate for use in coincidence experiments (a very novel procedure in 1924). Using two counters, they studied the coincidences between the scattered X ray and the recoiling electron. Correlating photons with electrons, Bothe and Geiger found a coincidence rate of one in eleven; since the chance coincidence rate for the situation was 10?5, the experimental results contradicted the theoretical predictions and indicated small-scale conservation of energy and momentum."

First apprance of a classic paper on forarms, describing many type-specimens. Parker became one of the greatest authorities on the Foraminifera, a group containing microscopic single-celled amoeboid protists with calcareous tests (shells).

It was Jones, mainly, who taught him how to present his considerable knowledge, and together they wrote 34 papers on the forams.
