The article focuses on the study of the influence of rabbits on the vegetation of various hill-grazing districts of Scotland. The rabbit burrows are in sand, light soil, usually with small stones or rubbles. Pentland Hills have extreme rabbit pressures, where vegetations like Ulex europaeus and Digitalis purpurea have been severely grazed. In Moorfoot Hills the burrows are scattered, so the pressure is not severe and a good grassy vegetation prevails. The vegetation in this region comprises of short dense Calluna vulgaris and small patches of Pteridium aquilinum. The chief changes that took place in this region are increase of grass and the plant species Galium saxatile. The first stage in destruction was the partial destruction of the vegetation covering the soil.

The article focuses on the study "Sur la Digitalis purpurea, plante calcifuge," by R. Chodat which focused on the calcifuge character of foxglove. In this paper, the author discusses the results of certain experiments which described the nature of the effect of lime on the growth of Digitalis purpurea. He observed that when basic carbonate of magnesium is added to the lime, the inhibitory action is increased. On the other hand, if dolomite is added to the original soil the retarding effect upon growth is less marked. The author concludes that the action of lime is due to its alkalinity in neutralising the acids of humus.
