 1908. In this wonderful deposit of fossils, specimens of Tri- 

 chophane8 foharum, of ('ope. were found. This little fish, of 

 which figures are given by Professor Cockerell, appears to belong 

 to the suborder Xenarchi, and to be a near relative of Aphre-

 History of the Fish," Mr. J. Arthur Button publishes, in the 

 form of a paper read before the Manchester Anglers Association, 

 an article in which he shows that the scales of salmon are ob- 

 tained through life, and that in a general way the age of the

In the American Journal of Obstetrics, Dr. Charles R. Stock-
