"Further Experiments on Artificial Parthenogenesis and the Nature of the Process of Fertilization" (1900), by Jacques Loeb

Jacques Loeb [5] broadened and corrected his earlier claims concerning artificial parthenogenesis [6] in sea urchins in a series of experiments in 1900. He published these findings, ?Further Experiments on Artificial Parthenogenesis [4] and the Nature of The Process of Fertilization,? in a 1900 issue of The American Journal of Physiology. His new results amended those from earlier experiments h...

"On the Nature of the Process of Fertilization and the Artificial Production of Normal Larvae (Plutei) From the Unfertilized Eggs of the Sea Urchin" (1899), by Jacques Loeb

Jacques Loeb [4] developed procedures to make embryos from unfertilized sea urchin [5] eggs in 1899. Loeb called the procedures ?artificial parthenogenesis," and he introduced them and his results in ?On the Nature of the Process of Fertilization and the Artificial Production of Norma Larvae (Plutei) from the Unfertilized Eggs of the Sea Urchin? in an 1899 issue of The American Journal of Physi...

The Pragmatism of Hilbert's Programme

On 17 June 1899 the Göttingen society took part in the festive unveiling of the Gauss-Weber monument in memory of the great mathematical and physical tradition of the University of Göttingen. On the occasion of this event a commemorative volume was published containing two contributions: Emil Wiechert’s paper on the foundation of electrodynamics (Wiechert 1899 ) and David Hilbert’s paper on the...

A new genus and species of Bruchinae, with a key to the genera from Australia (Coleoptera: Chrysomelidae).

A new genus of Bruchinae, Buburra Reid & Beatson, is erected for a single new species, B. jeanae Reid & Beatson. Buburra is endemic to Australia where it is known from a single site at high altitude in Victoria. The hostplant is unknown. Buburra is placed in the tribe Pachymerini. A key is provided for identification of the 12 genera of Bruchinae in Australia, including Caryotrypes Decelle, 196...
