The fact that the tenant became the owner of the equity of redemption would not in itself defeat the right to hold the mortgage title free from the claim of dower. The fact that he purchased the equity of the mortgagor, taking a conveyance by a warranty deed, “ subject to the mortgage,” would not affect his right to hold the mortgage as assignee by an after acquired title, with all the rights of the original mortgagee. A purchase of an equity of redemption is always a purchase of an estate subject to a mortgage. But the taking of a deed with the recital that the premises are subject to a mortgage does not import a promise on the part of the grantee to pay such mortgage.
The further inquiry is, whether this mortgage has been paid and discharged. It is said, on the part of the demandant, that such was the effect of the acts of the tenant in January 1859, when, according to the statement of facts, the tenant purchased the mortgage to Knox and wife, and took an assignment thereof to himself, paying therefor the full amount of the original note, and interest from its date, nothing having ever been paid thereon. Upon a careful revision of the cases to which we have been referred by the counsel for the demandant, we think they fail to sustain the position that this transaction amounted to a payment and discharge of the mortgage. It differs from many of them in the fact that this was a purchase, and in form an assignment of the mortgage. It differs from the cases where there was an agreement on the part of the purchaser of the equity that he would pay and redeem the mortgage.
It was said by this court in Brown v. Lapham, 3 Cush. 554, 555, if the money is advanced by one whose duty it is by contract or otherwise to pay and cancel the mortgage, and relieve the mortgaged premises of the lien, a duty in the proper per- ' formance of which others have an interest, it shall be held to be
