Prof. M'Intosh, of St Andrews, has recently published 1 

 a lengthy but very readable paper entitled, " General Remarks 

 on some Points in the Life-history of the Salmon, and a

 of Teleosteans." In this place it is impossible to summarise

Ornithologists will be much interested in a paper by 

 Julian S. Huxley on the " Courtship-habits of the Great 

 Crested Grebe." 4 This article forms an important contribu- 

 tion to the theory of Sexual Selection. It is divided into 

 two parts (1) General, and (2) Special. In the former there 

 are some six sections, dealing respectively with (1) the
