Considering these terms in their legal aspect, that is as indicating the interest in the thing rather than the thing itself, we find that there may be both real property and personal property in realty. From a technical, legal viewpoint, real property is any interest in realty which is measured as to duration by a life, or lives or longer. Any other interest in realty is personal property. The actual length of time is no criterion; the life may last only a few months or years, yet one who is entitled to use and enjoy realty during that period is possessed of a real property right therein.

If his righs be under a lease for 99 years (longer than the normal life) his interest, not being measured by a life or lives is personal property.
