PROF. H. E. ARMSTRONG'S recent reference in NATURE (Mar. 19, p. 432) to the salary attached to a lectureship in organic chemistry in the University of Sydney may create misapprehension unless it is pointed out that the general scale for lecturers in all subjects at Sydney is £350, rising by yearly increments of £40 to a maximum of £700 per annum. There is little doubt that the conditions for lecturers at Sydney are distinctly more favourable than those prevailing in many, if not most, of the universities of Great Britain.
