IN this week's number of NATURE I see it noted that among the courses of lectures announced for the ensuing winter by the Ladies' Educational Association in connection with University College, are included two upon scientific subjects (chemistry and experimental physics). May I venture to point out that the prospectus makes mention also of a third, namely, on logic, introduced by ten lectures on the psychology of intellect? This course was, certainly, designed as a scientific one, and indeed as a substitute for the course on mathematics suspended temporarily by force of circumstances. My own motive for drawing attention to the point will not, I think, be misunderstood, when so lately I had occasion in your columns to say a word for psychology as a natural science.
