of maritime documents may hasten this result by giving us a more complete 

 interpretation of the signs furnished by continental observations. We have 

 already seen in the Bulletin of Friday, 11th, that the concavity of the curves 

 of equal barometric pressure directed, December 1, 1862, towards tlie west, 

 on the Biy of Biscay, and the British channel coincided with a rotary storm 

 prevailing at the same instant in the neighborhood of the Azores, and des- 

 tined to discharge its violence, eight days afterwards, on the North sea.
