The plaintiff, upon the trial, to support his right to the possession of the property obtained by the writ of replevin issued in this cause, introduced in evidence the following receipt, which the defendant admitted was signed by him, to wit: “ Received, Iowa City, October 26th, 1858, from .Julius A. Reed, Treasurer of the Iowa College, the following described notes and accounts and *7personal property, to collect or sell the same, as may best secure the payment thereof, or otherwise as said Julius A. Reed, Treasurer, may from time to time direct, and account to him, the said Julius A. Reed, Treasurer, when called for.” A list of notes and accounts and other personal property is given in said receipt, and signed by the defendant.
The plaintiff after the introduction of this receipt, and evidence proving a demand, submitted the case to the jury.
The defendant was then introduced as a witness, and testified that the said written instrument read in evidence, was executed by defendant at the urgent request of one Lambrite, a member of' the firm of Burell, Grillett & Co. That the plaintiff, Julius A. Reed, was not present at tbe time when said receipt was signed, that when it was signed it was given to said Lambrite under an express understanding that the same was not to be delivered to the plaintiff until one James BL. Mills of Davenport, of whom the defendant was the agent, and for whom he held said property, should receive his pay, being the sum of $1,300; that the said Lambrite delivered said writing to the plaintiff in violation of said express agreement; that the said Mills had not yet been paid; that the defendant was only to account to plaintiff for the property after said Mills had been first paid and satisfied out of it; - that the plaintiff was, at the time of giving said receipt, the Treasurer of Iowa College, and had succeeded the said Lambrite, who was a defaulter, and indebted to the said College to the amount of about $7,000 and had asked defendant to give such receipt. Defendant further testified that, at the time of making said receipt, he was the agent of said Mills, and held the property in controversy for said Mills as his agent at the time suit was brought, that he had no authority from said Mills to execute and deliver to the plaintiff any absolute receipt for said goods, nor to give the receipt offered *8in evidence, and that Mills was still the owner of the said property at the time suit was brought. This testimony was given to the jury, notwithstanding the objections of plaintiff, to which, ruling the plaintiff at the time excepted. The said witness further testified that the property in controversy had been sold by Burell, Gillett & Co., of Davenport, to James K. Mills, of Boston, and by him, through his agent, James K. Mills, of Davenport, to Beed & Downs, of which firm defendant was a member, and by said Beed & Downs to James K. Mills, of Davenport. The records of Johnson county were also introduced, showing such transfers.
The plaintiff relied upon the receipt of defendant, and proof of demand, as sufficient to show his right to the property.
The defendant denied the ownership of plaintiff in the property, and claimed that the said Mills was the owner, and that he, as the agent of Mills, was entitled to such possession.
The plaintiff asked, and the court refused to give to the jury, the following instructions, viz.:
“That by executing the instrument dated Oct. 28th, 1858, the defendant acknowledged the ownership of, and right of possession, on demand, to the property therein specified, in the plaintiff, and cannot in this action defeat the right of the plaintiff to the possession on demand of the property, by showing that James K Mills was the owner of said property at the time said instrument was given by defendant.”
“ That by entering into the contract contained in said instrument, the defendant bound himself as a bailee under the plaintiff, and agreed to hold the property specified therein for the use of the plaintiff, the defendant cannot now show that at the time he signed said instrument that he, defendant, was the agent of Mills, and held the property as such agent.”
*9The court, upon its own motion, among other instructions) directed the jury as follows :
“ That the receipt introduced, without other evidence, entitles the plaintiff to the possession of the property as between the plaintiff and defendant, but if, at the time of the execution of the receipt, the property belonged to a third person, and the defendant had no authority, as agent of such third person or otherwise, to give such receipt, then the receipt conferred no such right on the plaintiff, and on such a state of facts he would not be entitled to the possession of the property.”
The admission of parol testimony to explain or vary the terms of the written instrument offered in evidence, and the giving and refusing to give the instructions asked by plaintiff, are the errors assigned.
The court below, in its instructions, correctly stated that the receipt itself, without any other evidence, would entitle the plaintiff to recover. The defendant, by the execution and delivery of the receipt, admitted that the property belonged to the plaintiff, and that he held the same as his agent or bailee. The defendant, in his answer, fails to aver that there was any fraud or false representations made at the time the receipt was given, nor does he plead the cotemporaneous contract that he seeks to establish by the evidence. The answer merely denies the ownership of plaintiff, and avers the right of possession to be in another. As between the plaintiff and defendant, there is no claim that defendant has the right to the possession in his own behalf, but claims that it is the property of Mills. Conceding that the rule is well settled in many of the states that the defendant in an action of replevin, may plead property in a stranger to the suit, and if such plea is supported by evidence, it is a good defense, yet is this rule applicable to this case, and will it apply under our statute ?
Independent of the provisions of our statute, upon the *10strength of authorities we would feel disposed to follow this rule, at the same time distrusting its correctness as not founded on very accurate reasoning. “ For the plaintiff,” says Nelson, J., in Rogers v. Arnold et al., 12 Wend. 30, “being in possession of the goods at the time of the caption, which is admitted by the plea, it is difficult to see how the defendant shows a right to the return of the property taken on the replevin by proving a title to it in a stranger.”
Under the provisions of the Code in relation to the rights of third parties, and under other well settled maxims of the law, this rule does not apply in this case.
The defendant when he executed the receipt to plaintiff, admitted the rights of possession in the plaintiff, and in order to show that it was the property of a stranger, he now seeks to avoid the effect of his own obligation. Having by his own acts admitted certain rights to the plaintiff, he is thereafter estopped from denying what has been thus admitted. For it is truly said by Chief Justice Tindal, in the case of Gosling v. Binnie, 7 Bing. 339 (20 Eng. Com. L. R 153), where the defendant had orally agreed to hold certain timber for the plaintiff, “This is an action of trover, in which I'agree that the question is, whether the plaintiff can show the property to be in himself, as to which, in the present case, the defendant is estopped by his own admissions; for unless they amount to an estoppel, the word estopped may as well be blotted out from the laws.”
The defendant does not by his pleading, nor dees the counsel claim by his argument, that the defendant in his own right is entitled to the possession of the property. It is claimed by him for Mills, a third party. Section 1999 of the Code provides, that if a third person claim the propertjr he must be made a co-defendant. The object of the defendant by his seeking to avoid the force of his o,wa *11agreement, is to show a title in a third party. If this third party claimed the property under our statute, he should have been made a co-defendant. Had this been done, the rule discussed so fully by counsel, in reference to the effect of a cotemporaneous contract being made at the time the receipt was given, might have been applicable.
The court erred in refusing the instructions above set out, asked by plaintiff, as well as in giving the one referred to, upon its own motion.
