None of these cases fill the void of appellant's admitted inability to designate one complete and certain description of this property. Appellant's cases of Morgan v. Stearns (1871), 40 Cal. 434, 438; Chatfield v. Williams (1890), 85 Cal. 518, 521 [24 P. 839]; and Porter v. Arnold (1955), 136 Cal.App.2d 636, 638 [ 289 P.2d 47], do not explain away appellant's multiple descriptions. The cases merely hold that a purchaser of real property bears no duty to prepare a deed; such is the obligation of the vendor.
