    from that point of view to be incompatible with the idea of radicals, but he now joins those chemists who find in each of these notions a necessary and most natural complement to the other. May we not hope that such may be the result in other cases of difference of opinion on scientific questions, which the progress of knowledge will shew to have been owing to the incompleteness and one-sidedness of each view rather than to any thing absolutely erroneous in either ? NOTE ON THE DECOMPOSITION OF SUL- PHURIC ACID BY PENTACHLORIDE OF PHOSPHORUS* CHEMISTS have long been aware of the fact that some acids unite with bases in one proportion only, others in two or more proportions. Thus a given quantity of nitric acid forms with what is termed its equivalent of potash, a definite nitrate of potash ; if less than this equivalent quantity of potash were added to the nitric acid, the product would be a mechanical mixture of the same nitrate of potash with uncombined nitric acid ; if more * [From Proceedings of the Royal Society of London., vol. vii, (1856), pp. II-15.]
