On more fully working out my system, I thought, however, that the term hypermetropia would he more in acoordanoe with the nomenclature I had already employed in the words ametropia and emmetropia, and this name has since that time been most generally adopted. My investigations respecting H are to be found in Ametropie en hare gevolgen, Utrecht, 1860, and in the Archiv fiir Ophthalmologic, Bd. vi., Abth. i., pp. 62-106, Abth. ii., pp. 210-243.
