¶1I. The testimony of the witnesses Brazil© and White, as shown by bill of exceptions, not only included the question of their opinion as to the amount of damages resulting directly from the alleged failure of appellant Turner to furnish the cistern, but also indirect damages to the crop of appellee Strange. We are of opinion that the testimony did not come within the exceptions to the general rule that witnesses must state facts, not draw conclusions or give opinions. Clardy v. Callicoate, 24 Tex., 170.
¶2Such exceptions ought not to be extended or enlarged so as to include new cases, except as a necessity to pre*143vent a failure of justice, and when better evidence cannot be had. Note 12 to 1 Whart. Ev., § 510.
¶3The facts which constituted the basis for such actual damages as the law would give under the proper allegations in this case, were of easy comprehension to an ordinary mind, and did not involve a question of skill, science, trade or other like character, about which, as an exception to the general rale, the opinion of an expert is admitted. Neither did it involve such question of value, founded upon the peculiar knowledge, skill and judgment of the witnesses, in regard to the particular or general subject matter under consideration, as brought it within another and kindred exception to this general rule.
¶4These exceptions are based upon the reason that the facts which constitute the cause from which the opinion of the witness is deduced as an effect, cannot themselves be so presented or communicated to the mind of the jury as to impart to them the knowledge actually possessed by the witness. Cooper v. The State, 25 Tex., 338.
¶5The facts testified to by the witnesses in this case were such as could be stated or described in language which would enable persons not eye-witnesses to form an accurate judgment in regard to them, and about which the jury were as competent to form a correct opinion as the witnesses, and hence did not come within the reason of the exception. 1 Whart. Ev., §§ 509-514, and authorities cited in notes; 1 Greenl. Ev., 440.
¶6The witnesses, under proper rales for the measure of damages, should have stated the several grounds which constituted the basis of damages, and the amount or value of these damages. These rules should have been given in charge to the jury for their guidance, and their verdict should have been founded upon this evidence as applied to these rales, and not upon the general opinions of the witnesses.
¶7It is true that they detailed the facts upon which their *144testimony was based, some of which were proper elements of damage, and this, as to these items, may have had the effect to correct any erroneous impression made by the evidence adduced, of their opinions. But so far as the court, over the objections of appellants, permitted them to give a general opinion of the amount of damages, when their opinion was based in part upon the loss of the crop, which was not, in this case, a proper ground for damages, we think there was error which may have misled the jury, and for which the judgment should be reversed.
¶8II. There was also error in the refusal of the court to give in charge to the jury the proper rales of law for the measure of damages in this case, and to which attention was called by special instruction number 1, asked by appellant and refused by the court.
¶9The general charge of the court on this subject was as follows: “ On the subject of damages, your consideration is to be confined to the actual damages resulting directly, and not indirectly from such breaches of the contract as may be respectively proved by the parties.”
¶10The charge was defective in not specially instructing the jury what, under the issues and evidence, were the rales of law by which they should estimate the damages as a question of fact. R. R. Co. v. Le Gierse, 51 Tex., 204.
¶11It is not deemed material to pass upon the other errors assigned, for if well taken they are of such character as will probably be avoided on another trial.
¶12For the two errors above indicated, the judgment below is reversed and the cause remanded.
¶13Reversed and remanded.
