    The same writer further charges it against me, that my re¬ flections on the spine and its diseases, which have been copied from my work into many of the periodicals, are an abstract, un¬ acknowledged, of the late Mr. John Shaw’s work on the subject. I should be pleased to think that in my four paragraphs on spinal diseases, I had so happily accomplished, as this censure would imply, the object aimed at throughout my volume, of condensing useful matter; but the fact is, that the paragraphs in question are very nearly the substance of my remarks habitually given to patients under spine disease, before Mr. Shaw’s work appeared. My respect for Mr. Bell had led me, from hearing it reported by others, that he descanted ingeniously on the anatomy of the skull, to find room, where few names appeared, for a special commendation of his labours ; and had I felt myself called upon, I should not have been behind in regard to Mr. Shaw, for whom, in common with all who knew him, I felt much regard.

The great majority of lakes, however, being basins constantly running over at one part towards the sea, although all originally salt, have in the course of time become fresh, because their only supply, being directly from the clouds, or from rivers and springs fed by the clouds, is fresh, while what runs away from them must always be carrying with it a ])roportion of any sub¬ stance that remains dissolved in them. We thus see how
