All in all, laboratory work was characterized by a large amount of uncertainty. Therefore, the communication and interaction of highly specialized scientists largely relied on trust.Chemist Carl Djerassi, father of the anti-baby (contraceptive) pill, included in his novel Cantor s Dilemma, a 1983 quote from the editor of the New England Journal of Medicine, Arnold S. Reiman It seems paradoxical that scientific research, in many ways one of the most questioning and sceptical of human activities,... 

From 1881 to 1890, textbooks written by Wilhelm Ostwald, Carl Arnold (1853-1929), and the now unknown Otto Hausknecht mention the periodic system. Max Zangerle developed his own so-called natural system, based on ylem atoms, and published it in his school program. Of the books examined from the years of 1870 to 1890, about 14 percent mention the system. The differences in Brush s data can be explained entirely by the number of books used. An exact number of all textbooks at that time was not available, and thus aU statistics are unreliable. 

Boubals (1966) was among the hrst to study phylloxera resistance and its heri-tability in both intraspecihc and interspecihc hybrids of V vinifera, V berlandieri, V. riparia, V. rupestris, V. cinerea and Vitis labrusca. In 1934, however, Carl Bbmer discovered total phylloxera resistance in V. cinerea Arnold and used this species in his breeding programme. V. cinerea shows a total resistance to this pest and was used to produce its hybrid with V. riparia 183 G, which was named Bomer (Becker and Bomer, 1988). Bomer responds to phylloxera infestation with a hypersensitive reaction, which results in local necrosis on leaves and roots so that the damage caused...
