METEOROLOGICAL REPORT.
In our Meteorological Report for the fast three months of this year, we gave the results of our observations, without any comparison between the last and the present year. It may not however be uninteresting to our readers to state, that the mean temperature of the four months of this year that have just elapsed, considerably exceeds the mean temperature of the corresponding months of last year. The difference of the month of January is 5°, February 6°, March 3°, and April 4°. The effects of this difference are quite obvious in the unusually forward state of vegetation in gardens and orchards, and would have been equally conspicuous in the corn-fields, but for the severe and long-continued drought.
