3. Les Determinations des longitudes et VHistoire des Chro- 

 nometres ; par Jean Mascakt, Astronomer at the Observatory of 

 Paris, pp. 62. (Ext rait des Journal, " L 'Horologier").— This is 

 an account of the development that took place from about 1760 

 to 1780 in methods of determining longitude and time, especially 

 at sea, and more particularly in making marine chronometers and 

 testing them on long voyages. The expedition of the Flora, 

 which was one of several chronometer-testing expeditions under- 

 taken for the first time at this epoch, and the most important of 

 them, is described at length. The transits of Venus which occurred 

 in 1761 and 1769 gave an impetus to progress in these lines, from 

 the demands which they made for accurate chronometers to be 

 taken to the widely separated stations at which the transits were 

 observed. w. b. 



4. Project for the Reform of the Calendar; by Carlos A. 

 Hesse, Iquique. Presented to the Fourth (Pan-American) Scien- 

 tific Congress. — The author would divide the year into 13 months 

 of 28 days each, the last month to be called Trecember, and the 

 odd day Jan. 0, and at leap year, 00. The numerous advantages 

 that would attend such an orderly arrangement are forcibly pre- 

 sented. 



The abstract proposition can hardly be contradicted, but the 

 irrational obstacles of tradition and mental inertia are pretty 

 certain to be insurmountable to this, as to other such attempted 

 revisions, for an indefinite period to come. 



The revised calendar, which would be perpetual, and which the 

 author would like to see introduced in 1912, would be as follows; 

 and "future generations would learn it by heart from earliest 

 infancy." w. b.
