This was when a common recovery was had, and an estate of freehold was first conveyed to anyindifferent person against whom the prcccipe was brought, and then he vouched thetenant in tail, who vouched over the common vouchee. For, if a recovery were had immediatelyagainst a tenant in tail, it barred only the estate in the premises of which hewas then actually seised, whereas, if the recovery were had against another person, and thetenant in tail were vouchee, it barred every latent right and interest which he mighthave in the lands recovered. 2 Bl. Comm. 359.
