But in most cases habit, however prolonged, appears to have little effect on the constitution of the individual, and the fact has no doubt led to the opinion that acclimatization is impossible.
The incoming of the Glacial epoch does not appear to have been accompanied by any acclimatization of the plants - the species belonging to temperate Europe were locally exterminated, and Arctic forms took their places.
The town lies among hills, has an excellent climate, and in colonial times was (like Holguin) an acclimatization station for troops fresh from Spain; it now has considerable repute as a health resort.
A large extent of open ground, to the west of the town, finely planted, and traversed by the river, comprises Hagley Park, recreation grounds, the Government Domain and the grounds of the Acclimatization Society, with fish-ponds and a small zoological garden.
The subject of acclimatization is very little understood, and some writers have even denied that it can ever take place.
