 It is arguable that (L) meets the criteria for lawfulness imposed by Hempel and many other writers. (If one wants to deny that (L) is a law one needs some principled, generally accepted basis for this judgment and, as explained above, it is unclear what this basis is.) Moreover,  (5)  is certainly a sound deductive argument in which (L) occurs as an essential premise. Nonetheless, most people judge that (L) and (K) are no explanation of (E). There are many other similar illustrations. For example (Kyburg 1965), it is presumably a law (or at least an exceptionless, counterfactual supporting generalization) that all samples of table salt that have been hexed by being touched with the wand of a witch dissolve when placed in water. One may use this generalization as a premise in a DN derivation which has as its conclusion that some particular hexed sample of salt has dissolved in water. But again the hexing is irrelevant to the dissolving and such a derivation is no explanation.
