410. Covenant does not enlarge grant.

The tenant cannot, by reliance on the covenant for quiet enjoyment, obtain over adjoining property an easement or right which was not included in the demise. The covenant does not enlarge what was previously granted, but gives an additional remedy if the tenant cannot get or is deprived of that which has been previously professed to be granted1. Consequently, where the tenant has not acquired a right to light or to the access of air, he may not complain of interference with light or air as a breach of the covenant
