delivered the opinion of the Court.

This is the second appeal in this case. The facts out of which it arises are fully set out in connection with the decision of the prior appeal, reported in 124 Md. 110, and the case of Furness-Withy & Co. v. Gill & Fisher, 124 Md. 101. In the first appeal this Court passed upon the pleadings, the refusal of the Court to admit certain evidence, and the instructions given to the jury, and the case was remanded for a retrialj because of the errors pointed out in the opinion referred to, in order that the question of whether the three contracts, dated respectively September 21st, 23rd and Octobr 4th, had or had not been modified by a notification by the appellant and “O. K.” of John T. Fahey & Co., and if those contracts had been modified, then to determine what the contracts between the parties were.

On the second' trial of the 'ease, the pleadings having been completed in accordance with the opinion of this Court, there was left for the determination of the jury, under the stipulation of the parties, only the questions above indicated. As now presented the case comes to this Court upon ten exceptions, reserved to the rulings of the Superior Court upon questions of evidence, none in any way involving the instructions given to the jury, and whether those instructions were correct or not is not now before this Court for consideration.

*335 While the exceptions are ten in number, they all were reserved upon a single theory, so that a seriatim discussion of them is not necessary to a conclusion of this case.

By the pleas which had been filed, the defendant set up as a defense to the plaintiff’s recovery, under the three several contracts of September and October, that there had been a parol modification of them, and that modification consisted in notifications on December 2nd designating the ship “Amana” as the particular vessel to carry the grain contracted to be transported by the original contracts; these notifications were in practically identical form, as follows:

“Baltimore, Dee. 2, 1911.

“Mess. John T. Fahey & Co.,

“City.

“Dear Sir — We beg to name steamer ‘Amana’ expected to sail for Eeith Dec. 27th, for 3,000 quarters grain.

“Engagement of Sept. 21, for 3,000 quarters, eon- ■ tract No. 59.

“Respectfully,

“Dresel, Rauschenberg & Co.,

“Signed) “Agents.

“OK. “Per A. F. Sidebotham.

“John T. Fahey & Co.”

Of such notice it was said in Furness-Withy & Co. v. Gill & Fisher, 124 Md. 107: “The effect of this was to render more definite, in one particular at least, the terms of the original contract; and the assent to- it on the part of the shipper amounted to a modification of the original contract by mutual consent at a time when it was perfectly comper tent for the parties so' to do-, and substitute a particular ship, in place of an. open contract which wo-uld be gratified -by the sending of any ship of that line.”

That language was- predicated upon the assumption, that the words used had a definite, well-understood meaning, and that it was the same in the minds of both parties to the *336 contracts. If such was the case then the jury would have so found, but if in point' of fact there was-not such common understanding, then there had been no- meeting- of the minds, and therefore no modification of the original contracts. -This was-a' question- of - fact-tb- be determined by-a-jury,.-not one'of law for the--Court. -The questions put To-'the-witnesses-to which objections were made,-and to-the-admission of answers to which the exceptions were-reserved- sought in one way- or another to show what'-the understanding of the parties was with'-reSpect:to the nomination of December- 2nd.- 'It must be borne'in-mind that the suit- as-instituted declared on the original contracts, and that the -alleged-modification of-them had been set up by the defendant, thus casting upon it the burden of proving such modification.

The appellant now claims that in showing the understanding of the meaning of the notification ,of December 2jid and the “O. K.” of the plaintiff, thereon, the plaintiff is restricted to evidence of acts, and cannot show by parol testimony, what that understanding was, because to do so would infringe the rule that parol evidence cannot be given to, vary, alter or modify a written agreement between parties. _ This contention misconceives the real issue in the case, viz., whether the written notice of December 2nd was in fact the- agreement of the parties, and to be given the full, legal effect of an agreement, or was inoperative and void as never -having expressed the real intent of the parties. The line of distinction between-these two positions is well-recognized in principle, though the facts of any particular case may bring-it into- a “twilight zone.” ’

The admissibility of parol evidence to show that there was never a real meeting of the minds has been established by a long line of decisions in this State, the leading one among which is the Southern St. Ry. Adv. Co. v. Metropole Co., 91 Md. 61, in which following the earlier cases of Davis v. Hamblin, 51 Md. 525, and Harrison v. Morton, 83 Md. 456, the rule is announced in these terms: “The rule which excludes parol or verbal evidence to affect that which is writ *337 ten, was not at all infringed by tbe admission of such evidence to show that the instrument was void or that it never had any legal existence or binding force for want of due delivery and acceptance.”

In the same opinion the English cases are cited, and’the English rule summarized as follows: “The distinction in point of law is that evidence to. vary the terms of an agreement in writing is not admissible, but evidence to show that there is not an agreement at all'is admissible.”

And the same rule is adhered to in Birely & Son v. Dodson, 107 Md. 229; Colonial Park Estates v. Massart, 112 Md. 648.

In this last case it was said: “If, therefore, the jury believed Massart’s testimony as to the circumstances and understanding under which the $250 were paid by him to the company * * * and there was no binding contract of sale between the parties, the plaintiff” was entitled to recover. In the view of this Court the facts and circumstances of this case bring it clearly within the line of these decisions, and no error can be attributed to the lower Court for its rulings which form the bases for the 1st, 2nd, 3rd, 4th, 5th, 6th, 8th and 10 th bills of exceptions.

Some of the questions might have been objected to on other grounds, as palpably leading, but no such objection appears to have been made below, nor has it been pressed here. In each instance where such a technical objection might have been interposed, the evidence so sought to have been elicited came in elsewhere without objection, and no reversible error can be predicated upon the admission of evidence over objection, when the same evidence comes into the case elsewhere unobjected to. Black v. Bank of Westminster, 96 Md. 399; B. & O. R. R. Co. v. Deck, 102 Md. 669; Parks v. Griffith & Boyd Co., 123 Md. 234; Rice v. Dinsmore, 124 Md. 276.

The 7th and 9th exceptions present a somewhat different question. On cross-examination the agent of the appellant was asked as to the steamers of the appellant company, other than the “Amana,” trading to the ports of Baltimore, Phila *338 delphia or Newport News, at or about the period of time of the Fahey contracts. In the form in which the question was put it was liable to have misled the jury, but that no injury resulted to the appellant is clear. Any possible injury that could have resulted from these questions was obviated by the stipulation of the parties as to the amount of the verdict in the event of any verdict being rendered for the plaintiff. So, even if it be assumed that there was error in permitting these questions to be answered, which is not now decided, the error would constitute no ground for reversal, since it occasioned no injury to the appellant.

The instructions granted by the Court were incorporated in the record, though no exception was reserved to them, and they have not been considered in reaching a conclusion. It is only just to say, however, that they placed the true issues of the case fully and fairly before the jury. Finding no reversible error in the rulings of the Court below the judgment appealed from will, therefore, be affirmed.

Judgment affirmed, with costs.
