JUMPING BEANS; A CORRECTION. 



The compositor in setting up my note on the Mexican jumping 

 seeds unfortunately dropped three lines of the manuscript, and caused 

 me to say " Well the exact name of the apple-worm is Carpocapsa 

 salita/is,'" and as the proof of this note (p. 125) was read hurriedly, after 

 the rest of the November number had been revised, the error was over- 

 looked. What I had written was as follows : "Well the exact name 

 of the apple-worm is Carpocapsa pomotiella, and the motive power of 

 the jumping bean is the grub of a near relative of the coddling-moth, 

 which has been christened " Carpocapsa saltitanx." The so-called 

 " beans " also are not the seeds of the plant but the carpels. The ovary 

 is three-celled, and each carpel contains but a single seed, which is 

 entirely devoured by the grub, and the beans which we see are the 

 empty carpels. Ed.

The Cretaceous System in Canada. Presidential addiess, Section 

 IV, Royal Society of Canada, by J. F. Whiteaves, Montreal, November, 

 1893. This paper gives a comprehensive resume, to date, of the various 

 researches andresultsobtained in the palaeontological investigations of the 

 Cretaceous System in Canada. The first part of the address deals with 

 the bibliography of the subject, twelve papers having been published 

 before 1867 by various writers: Meek, Newberry, Shumard, Hector, 

 Bauerman, Heer, Etheridge and Gabb having contributed to the 

 literature in question. Here Mr. Whiteaves adds that: "With the 

 birth of the new Dominion, however, the conditions were changed, and 

 the seventeen annual reports published since 1867, with many special 

 publications not included therein, will abundantly show how far the new 

 obligations imposed upon its staff have been met." Since 1867 the 

 knowledge of the rocks and the fauna and flora entombed in them has 

 increased from year to year, until now we find that the Cretaceous rocks 

 of Canada are as well, if not better, described and known as the rocks 

 of any other epoch in geology. The stratigraphical relations of the 

 various subdivisions of the Cretaceous rocks to each other and to the 

 overlying newer or underlying older rocks have been described by Drs.
