An encyclopædia of gardening; comprising An encyclopædia of gardening; comprising the theory and practice of horticulture, floriculture, arboriculture, and landscape-gardening, including all the latest improvements; a general history of gardening in all countries; and a statistical view of its present state, with suggestions for its future progress, in the British Isles encyclopdiaofg00loud Year: 1827 Book IV ACCIDENTAL ACCOMPANIMENTS. 1017 vary according to its distance, the inclination it makes with the horizon, and our rela- tive* elevation or depression. A correspondent of Repton states, that ' any two of the above three things continuing the same, the apparent magnitude will decrease with the third, though not in exact proportion to it. Thus, the object being perpendicular to the horizon, and our elevation remaining the same, its apparent height will decrease with the distance. Our elevation and the distance remaining the same, the apparent height of the object will decrease with its inclination to the horizon. The inclination and distance beino- the same, the angle, or apparent height, will decrease with our elevation or de- pression, supposing our height was at first the middle point of the object. This last beino- liable to some exceptions, the general rule is, that the distance from the object, measured by a perpendicular to it, the point at which its apparent height will be greatest is, where the perpendicular from the eye falls upon the centre.' 7241 The difficulty in this subject is to know what the conception is that we shall form of the height and magnitude of an object according to different circumstances; its apparent height, as well as its real height, remaining the same. This cannot be reduced to rules, but depends chiefly on a careful comparison of particular instances. One cause, Repton considers, may proceed from the position of the eye itself, which is so placed in most foreheads as to view a certain portion of the hemisphere without any
