It is a well known fact that the flight of moths and some other insects is affected by barometric pressure, but it is not well known how this phenomenon affects other insect activity. In a study of the ecology of insects in vegetable gardens at Brandon, Man., in 1948, the relationship of barometric pressure to insect activity was recorded.It was noted in the field that the imported cabbageworm adults behaved differently under varying weather conditions. During warm, clear days they did little but move about freely and feed, but on days that were overcast, particularly preceding rain, they became active about the plants and appeared to be engaged mainly in egg laying.

AbstractThe aim of the study was to demonstrate the relationship of egg weight and egg quality traits with storage time and type of cages in which the laying hens were kept. The material consisted of 960 eggs from same age Hy-Line Brown hens kept in conventional and furnished cages at the same time in one building. The eggs were randomly collected, sorted by weight (S, M, L and XL), and stored under controlled temperature and humidity conditions. All eggs were weighed on days 1 (day of laying) and 28 of the experiment. During the same time they were candled to determine depth of the air cell, and 60 eggs from each subgroup were chosen to evaluate quality traits (egg weight and egg specific gravity), shell characteristics (shell strength, weight, thickness and density), and interior quality of eggs (albumen height and pH, yolk colour, weight and pH). The eggs (especially those from the heavier weight classes, XL and L) from hens reared in furnished cages were characterized by significantly smaller quality changes (egg weight loss, yolk proportion, albumen height, Haugh units) due to storage time in relation to those from hens kept in conventional cages. This fact could point to their better suitability for consumption. In addition to the housing system, changes occurring in eggs during storage should also be considered in terms of their weight class. Economically important egg traits (e.g. egg weight, shell strength) were better in eggs from furnished compared to conventional cages.

The Relationship

The determination of the relations, if any such exist, between volcanic activity and certain astronomical or meteorological phenomena, cannot fail to throw much light upon the vexed question of the solid or liquid condition of the earth’s interior. M. Perrey, as the result of his careful catalogue of earthquake phenomena, believed himself to have proved that these could be shown to have certain maxima and minima, which correspond with positions of the moon in relation to the earth and sun; there are many considerations which point to the conclusion that great and sudden changes in barometric pressure may be followed by outbursts of volcanic violence; and, finally, if the eruptions of volcanoes, as many geologists believe, are due to water percolating from the surface to a heated magma, rainfall must have no inconsiderable influence in determining the periods of their occurrence.
