In Hagerty v. Lee, 45 N.J. Eq. 1; affirmed, 45 N.J. Eq. 255, an injunction against obstructing light and air was denied by Chancellor McGill because although two windows would be closed and two others partly obstructed the court found that the proofs did not show that the use of the premises were not rendered "decidedly uncomfortably" because the passage of light and air was not substantially hindered. Also compare Liedtke v. Lipman, 76 Atl. Rep. 463; Greer v. Van Meter, 54 N.J. Eq. 270 (at p. 272); Ware v. Chew, 43 N.J. Eq. 493 (at p. 500); Bloom v. Koch, 63 N.J. Eq. 10; Cerra v. Maglio, 98 N.J. Eq. 481;Angalias v. Hirschfield, 99 N.J. Eq. 622. A careful consideration of the proofs fail to establish that any loss of business which was suffered or any substantial interference with the beneficial use of the premises resulted by reason of any claimed diminution of light, air or view.

In addition to the authorities cited by Chancellor Runyon in the principal case of Sutphen v. Therkelson, Mr. Stewart has added a number of additional authorities in a note. The same question arose and was dealt with by Vice Chancellor Bird in Ware v. Chew, 43 N. J. Eq. 493, 11 Atl. 746. There the complainant was a mere lessee of a one-story building adjoining a vacant lot, and with windows overlooking it, belonging to the lessor, which was afterwards sold by the lessor to the defendant Chew, who proposed to erect a building on it whose walls would be 3 feet and 8 inches distant from the windows in the complainant's building; and he was enjoined.
