Figure 8. Alternative and updated periodic table, adapted from tables developed by Thomas Bay ley, Jurgen Thomsen and Niels Bohn These tables all depict the symmetrical nature of the periodic law regarding the increase in intervals before periodicity occurs in every other period with the exception of the first one. Tie lines denote chemical analogies.

At very great dilution A approaches a limiting value (Schiiller, 1869 Thomsen, 1870 Marignac, 1871-6). 

In spite of the fact that the general statement of this principle has been shown to be false from all standpoints, it must be admitted that its enunciation was quite in harmony with the spirit of the times the great physicists Lord Kelvin (1851) and Helmholtz (1847) had previously formulated an identical principle in connection with galvanic cells. Thomsen and Berthelot went wrong, not in tlieir enunciation of the so-called theorem as a working hypothesis, but rather in their...

Nernst, in his Theoretische Chemie, devoted a whole chapter to a critical examination of the rule of Thomsen and Berthelot, and he concluded that in many cases the heat of reaction certainly does correspond very closely with the maximum work, AT, which latter magnitude he took from van t Hoff as a measure of the chemical affinity. Whilst pointing out that it very often gives results wholly incompatible with experience, and cannot therefore be indiscriminately applied, Nernst showed that the rule nevertheless holds good in too many cases to be wholly false in an appropriate metaphor he claimed that it contains a genuine kernel of truth which has not yet been shelled from its enclosing hull. This labour of emancipation was partially effected in the newer work of the same author, Applications of Thermodynamics to Chemistry, 1907, which is an attempt to place the rule of Berthelot on a scientific basis, and to determine under what conditions its use is legitimate. He points out that the equation ...

The predominant feature of Thomsen s disease is severe myotonia, worse in the cold and early morning than later in the day or in the warmth, unassociated with significant muscle weakness, degeneration, or other severe pathology. Myotonia is particularly common in ocular muscles, and muscles of the arms and legs. Onset is typically during childhood. 

There is no single underlying cause for the myotonia seen in the muscles of myotonic patients. The typical myotonic response is a train of action potentials generated in a muscle fiber in response to a single stimulus. Experimental work has shown that such a response can be generated in normal muscle fibers in which chloride conductance is suppressed, and this may be the cause of the myotonia of Thomsen s disease (see Barchi, 1988 for examples). It is almost certainly not the cause of myotonia in myotonic dystrophy in which there is an associated fall in...
