Excerpt from Report of Observations of Injurious Insects and Common Farm Pests, During the Year 1895: With Methods of Prevention and Remedy The observations of the past year have given us an unusually good opportunity of remarking how far amount of presence of injurious insects may be affected (or not affected at all) by exceptionally low temperatures, such as those from which we suffered in January and February of 1895. From records of extreme lowness of temperature taken from instruments in the regular Stevenson's screens, we find the extraordinarily low minima that were registered at various stations from Aberdeen to Kent, thus ranging at distances from the North of Scotland to the South of England. These show readings below zero as follows: -17° at Braemar, Aberdeen, -13° Esthwaite, Lancashire, -8° Ketton, Rutland, -5° Loughborough, and -8° Bromley, Kent. That is to say, in the popular manner of expressing amount of cold, temperatures in order given above respectively of forty-nine, forty-five, forty, thirty-seven, and forty "degrees of frost" - i.e. degrees below freezing-point, which is 32° Fahrenheit. At Loughborough the "mean" of the temperatures of the ten days from the 5th to the 14th of February inclusive was only 16.5 - that is, within a few fractions, sixteen "degrees of frost." These notes refer to the air temperatures, of which full records are given in our meteorological publications, and also with additions of local circumstances exceedingly serviceable for comparison with subsequent local insect conditions, and in the 'Times' daily meteorological reports published during the continuance of the unusual cold. But beyond this, and in regard to the still more important point as to effects on insect life of the amount of cold to which they are exposed in the ground wherein they lie, I take leave to quote Mr. Symon's swords: "Another striking proof of the severity of the 1895 frost is afforded by the temperature of the earth ('Monthly Meteorological Magazine' for March, 1895).
