On the Theory of Correlation for any Number of Variables treated by a New 
System of Notation, by G. Udny Yule. Proceedings of Royal Society, A, 
Vol. 79, 1907. 
A restatement of the theory of correlation. Although the new system of notation does not 
appeal to one very favourably on a first reading, the results follow easily when the notation 
has been mastered. 
Frequency Curves and Moments, by Robert Henderson. Journal of Institute 
of Actuaries, July, 1907, 
A reprint of a paper which appeared recently in the Transactions of the Actuarial Society 
of America. It deals with the Sheppard adjustments and Pearson Type curves. The latter 
are re-numbered and the normal curve appears as Type I, and the Pearson Type III is called II. 
The paper suffers from the defects of giving in no case a reference to the original author or 
to a memoir whence the results are reproduced. 
The Scope and Importance to the State of the Science of National Eugenics. The 
Fourteenth Boyle Lecture, by Karl Pearson, F.R.S. London, Henry Frovi^de, 
1907. 
If the object of National Eugenics is to be attained it is necessary that the general public, 
or at least the leaders of public opinion, should appreciate its aims and the results of modern 
statistical work on heredity and kindred subjects. The general results of the work on eugenics 
and the practical conclusions to which they tend are dealt with forcibly and clearly in the 
Lecture, which should do much to awaken interest in the subject among thinking people. We 
earnestly hope that at no very distant date there will be the "strengthening of racial conscience" 
and the "scientific basis of conduct" for which Professor Pearson calls.
