On the trial of this case the plaintiff, to prove that the horse sold him by the defendant was not safe, kind and gentle, as it was warranted to be, offered certain witnesses, who, after they had testified pai’ticularly to their knowledge of facts and of the conduct of the horse on various occasions, were asked this question:—“ From your knowledge of the horse was he in your opinion a safe, kind horse ?” The counsel for the defendant objected to this question, but the court admitted the evidence in connection with the facts. Was this ruling correct?
The general rule is that witnesses must state facts and not their individual opinions, but there are exceptions to this rule as well established as the rule itself. Besides the case of experts where the subject matter requires special study, skill and experience, the opinions of common observers in regard to common appearances, facts and conditions have been received as evidence in a great variety of cases.
Thus, such opinions have been received in questions of identity as applied to persons, animals, handwriting, and sounds, and in estimating the size, weight, distance and color of objects. State v. Shinborn, 46 N. Hamp., 497. Also to show the direction of force as evidenced by its effects. Steamboat Clipper v. Logan, 18 Ohio, 375. That certain blood *12stains came from below upward. Commonwealth v. Sturtivant, 117 Mass., 122. That certain foot-prints corresponded with certain boots. Commonwealth v. Pope, 103 Mass., 440. That certain hairs were human. Commonwealth v. Dorsey, 103 Mass., 412. That a place in a highway was bad and dangerous. Lund & wife v. Inhabitants of Tyngsborough, 9 Cush., 36. That a highway or bridge is safe. Ellsworth, J., in Dunham's Appeal from Probate, 27 Conn., 198. That a heap of stones in a highway was an object calculated to frighten horses of ordinary gentleness. Clinton v. Howard, 42 Conn., 294. That effluvia from a certain privy and pig-sty necessarily rendered the plaintiff’s house uncomfortable as a place of abode. Kearney v. Farrell, 28 Conn., 319. That a certain dam was sufficient to withstand the force of a certain stream of water. Porter v. Pequonoc Manufacturing Co., 17 Conn., 253. That a person was intoxicated. People v. Eastwood, 14 N. York, 562. That one appeared sad. Culver v. Dwight, 6 Gray, 444. That a person was of a certain age. De Witt v. Baily, 17 N. York, 344; Morse v. State, 6 Conn., 9. That one is sane or insane. Grant v. Thompson, 4 Conn., 209; Kinne v. Kinne, 9 Conn., 103; Dunham's Appeal from Probate, 27 Conn., 192. That a person evinced a change in intelligence or a want of coherence in remarks. Barker v. Comins, 110 Mass., 477; Nash v. Hunt, 116 Mass., 237. That persons appeared attached to each other. McKee v. Nelson, 4 Cowen, 355. That a horse appeared well and free from disease. Spear v. Richardson, 34 N. Hamp., 428. That a horse’s feet were diseased. Willis v. Quimby, 31 N. Hamp., 485. That a horse had a sulky disposition. Whittier v. Franklin, 46 N. Hamp., 23.
These exceptions to the general rule are allowed on the ground of necessity, where the subject of inquiry is so indefinite and general as not to be susceptible of direct proof, or where the facts on which-the witness bases his opinion are so numerous or so evanescent that they cannot be held in the memory and detailed to the jury precisely as they appeared to the witness at the time.
To render opinions of common witnesses admissible it is *13indispensable that the opinions be founded on their own personal observation, and not on the testimony of others, or on any hypothetical statement of facts, as is permitted in the case of experts. In some of the cases it is held that the opinion can only be received in connection with facts stated by the witness. In other cases this is not required; as, for instance, in questions respecting the identity of persons. A witness well acquainted with another usually identifies him without conscious mental effort in the way of comparison or inference. In the absence of striking peculiarities of form or feature the identification may be, and often is, by the mere expression of countenance, which cannot be described. And the witness may be correct in his opinion, and yet be unable to give a single feature, or the color of the hair, or the eyes, or any particulars as to the dress. In such cases the distinction between opinion and fact is so very nice that it might perhaps have been as well to consider such identification as a fact, like any other direct perception of the senses.
Where the disposition of a person or of an animal (as in this case) is to be ascertained, the fact to be proved, being latent, can be ascertained only by symptoms and outward manifestations. If these happen to be very striking they may remain in the memory and can be stated, but in many cases they are very slight in each particular instance, and only the impression of an indefinite number of such appearances remains, resulting in an opinion that the quality or disposition in question exists.
In all cases it is important, with a view to confirm the opinion, that the witness should be able to state such facts as will show presumptively that his opinion is well founded. But it is not quite correct to say that the opinion of a witness is entitled to consideration only so far as the facts stated by him sustain the opinion, unless the proposition is understood to include among the facts referred to, the acquaintance of the witness with the subject matter and his opportunities for observation. The very basis upon which, as we have seen, this exception to the general rule rests, is that the nature of the subject matter is such that it cannot be reproduced or *14detailed to tlie jury precisely as it appeared to tlie witness at tlie time.
We think the defendant was not aggrieved by the ruling of the court in admitting the evidence objected to, and his motion for a new trial is therefore denied.
In this opinion the other judges concurred.
