There it is shown on page 10 how at 8 of the 6th, ' neither the daily chart nor the barograms showed any very serious sign of disturbance.' On page 11 there is the following remark : ' The facts appear to show that the gale which ensued on our coast was to the full as much to be attributed to the advance of the high pressure Westward from Eussia, as to that of the low pressure Eastward from the Atlantic.' The isobars on our charts for the 6th, 7th, and 6th, seem to prove the force of this remark. Whatever may be the cause of these areas of lowest pressure, the five diagrams which follow the charts, as well as a large number of others received from the commanders of steamers to and from America, who are observing for this office, show that very many of them are experienced in the Atlantic, and the difference between the barometer curves of outwarc? and homeward bound steamers, as well as the extracts from logs, show that they are travelling to the North-Eastward. Normal state of Atmospheric Pressure and Wind between England and North America in Winter. Undulations of Barometric Pressure moving 30 to 40 miles an hour to the North-Eastward, with their accompanying Winds. We have, then, two important facts: 1. By consulting Buchan's Isobars, we nd that during the winter months the normal state of pressure is high over the land on each side, and low over the sea in the central part of the Atlantic, also that the pressure gets lower as you go North from the Azores. Let the line A B C in the diagram above be supposed to represent a section of the normal state o
