Diflfiisive processes nonnally operate in chemical systems so as to disperse concentration gradients. In a paper in 1952, the mathematician Alan Turing produced a remarkable prediction [37] that if selective diffiision were coupled with chemical feedback, the opposite situation may arise, with a spontaneous development of sustained spatial distributions of species concentrations from initially unifonn systems. Turmg s paper was set in the context of the development of fonn (morphogenesis) in embryos, and has been adopted in some studies of animal coat markings. With the subsequent theoretical work at Brussels [1], it became clear that oscillatory chemical systems should provide a fertile ground for the search for experimental examples of these Turing patterns.

The second type of coalescence arises from the rupture of films between adjacent bubbles [Vrij and Overbeek, y. Am. Chem. Soc., 90, 3074 (1968)]. Its rate appears to follow first-order reaction kinetics with respect to the number of bubbles [New, Proc. 4th Int. Congr. Suif. Active Substances, Brussels, 1964, 2, 1167 (1967)] and to decrease with film thickness [Steiner, Hunkeler, and Hartland, Trans. In.st. Chem. Fng., 55, 153 (1977)]. Many factors are involved [Biker-man, Foams, Springer-Verlag, New York, 1973 and Akers (ed.). Foams, Academic, New York, 1976].

Arable farmers in the UK rarely grow more than one crop in a year, but horticulturalists may grow two or more crops in a year on the same soil, so the question of crop sequences is more intense for them, particularly as Brassica vegetables, such as cabbages and brussel sprouts, can leave large organic as well as mineral nitrogen residues.

The Council of the European Economic Community, established under the 1957 Treaty of Rome, in 1973 issued a declaration on the environment (4), which the European Commission in Brussels has interpreted as giving it authority to issue directives on matters related to the emission of air pollutants, such as one limiting the sulfur content of fuel oil (5).
