Land Meteorology of the British IslandThe seven observatories are in active operatioThe publication of the Quarterly Weather Report has been carried on steadily, and the last part of the volume for 1869 appeared at the close of the financial year. The arrears are being steadily worked off.Arrangements have been made for the production of the plates by copperplate printing, and consequently an additional clerk has been engaged for the purpose of working Wagner’s pantagraph.OfficTbe expenses of management in salaries and wages have been 1,195. 7ft, as compared with 1,562. la 3 in the previous year.

The whole of this information is compressed, with perfect clearness, into a single 4to. platThe difficulty which has had to be overcome, lay not only in the bulk, but also in the proportions of the traces varying in different dimensionOn the one hand it was found that the horizontal scale might be considerably compressed, without loss of clearness, when the somewhat blurred line of the original trace was replaced by the delicate clear line of a copper engraving. On the other hand, it was found that the vertical scales did not admit of much reduction with advantage, and again that the vertical scales of each separate barogram and pair oi thermograms required small corrections.
