| (a) | - | By the custom of a certain village every cultivator of village land is entitled, as such to graze his cattle on the common pasture. A having become the tenant of a plot of uncultivated land in the village breaks up and cultivates that plot. He thereby acquires an easement to graze his cattle in accordance with the custom. |
| (b) | - | By the custom of a certain town an owner or occupier of a house can open a new window therein so as substantially to invade his neighbour's privacy. A builds a house in the town near B's house. A thereupon acquires an easement that B shall not open new windows in his house so as to command a view of the portions of A's house which are ordinarily excluded from observation, and B acquires a like easement with respect to A's house. |
