The Industrial Commission awarded compensation for 250 weeks for total loss of an arm, and also awarded 150 weeks or 30 per cent of 500 weeks for permanent partial disability to the back under the “other cases” provision of 85 O. S. 1941 § 22, as amended in 1941.
Complaint is here made only as to the method of calculating the award.
Petitioners say:
“The chief complaint and contention of respondent and insurance carrier is that the Commission erred as a matter of law in that the computation of the disability to the back was based upon 500 weeks or a total permanent disability without taking into consideration the loss of the arm.
“It is the contention and position of respondent and insurance carrier that the Commission should have followed one of two methods in computing the permanent disability:
“First: Subtract the total loss of the arm, or 250 weeks from a total permanent, or 500 weeks, apply the determined 30% partial permanent disability to the remainder or 250 weeks, and add the result to the total loss of the arm.
“This would compute in the following manner
“500 weeks
“250 weeks total loss of arm.
“250 weeks X 30% equals 75 weeks partial permanent disability to the back.
“250 weeks plus 75 weeks equals 325 weeks, multiplied by the maximum rate of compensation or $18 per week would award the total amount to which claimant would be entitled to in this matter.
“Second. Add the disability to the arm, or 100% to the partial permanent disability to the back as determined by *645the Commission or 30%, divide the result by 2, and compute on the basis of 500 weeks or a total permanent.”
Concerning the first suggestion above noted. The object of the Workmen’s Compensation Act is to compensate, within the limits of the act, for loss of earning power occasioned by injuries to me body, disabling one in the performance of ordinary manual or mechanical labor. United States Casualty Co. v. Steiger, 179 Okla. 407, 66 P. 2d 55, and cases therein.
The act arbitrarily provides for an award of 250 weeks for loss of an arm, leaving open no inquiry of fact in that regard. See discussion in Mudge Oil Co. v. Wagnon, 193 Okla. 466, 145 P. 2d 185. Other such disabling injuries, not within the so-called “specific” or “schedule” disablements, are determined under the “other cases” provisions of the act.
In cases such as this the award must be made for the arm loss as arbitrarily provided by the act, which was done in this instance, and also for the “other cases” disablement without regard to the arm loss and the award arbitrarily required therefor. Eubanks v. Barnsdall Oil Co., 169 Okla. 31, 35 P. 2d 873, and Mudge Oil Co. v. Wagnon, supra.
It follows that the award for the arm loss is fixed at 250 weeks without regard to inquiry into further facts or what such inquiry would disclose in a given case. But there then remains in this case another disabling injury which is open to inquiry as concerns certain factors to be employed in calculating the amount of an award. We resort to the “other cases” provision of section 22 of the act, supra. The same provides:
“Other cases: In all other classes of disabilities, excluding only those heretofore referred to in subdivision three, which disabilities result in loss of use of any portion of an employee’s body, and which disabilities are permanent in quality but partial in character, the compensation ordered paid shall be sixty-six and two-thirds per centum of the average weekly wage during that portion of the number of weeks which the partial disability of the employee bears to the total permanent disability.”
The subject of that provision is disabilities other than those otherwise provided for. Disabilities within the meaning of the act refer to lack of ability to do ordinary manual or mechanical work and labor, and a partial disability when considered in terms of percentage refers to a percentage of the whole of the subject matter.
The “other cases” clause, providing as it does for partial disability, could reasonably be construed in no other manner than that it refers to the partial disability as compared with 100 per cent ability. Therefore, if one has an injury within the “other cases” provision of the act which, standing alone, reduces his ability to work 30 per cent he is entitled to an award for 30 per cent of 500 weeks as provided thereby. The commission herein found that the percentage of disability present within the “other cases” provision was separate and apart from the arm loss.
One of the fallacies present in petitioner’s first suggested method of calculation is failure to take into consideration the fact that the arbitrary requirement of the use of 250 weeks as a factor in calculating the award for the loss of the arm does not necessarily mean that the claimant has in fact thereby lost 50 per cent of his total ability. Another is the fact, as found by the commission, that the “other cases” injury incapacitated the man 30 per cent separate and apart from the arm loss. The arbitrary requirements of the statute do not necessarily coincide with facts which the commission may find as concerns questions open to it, and for that reason the arbitrary factor and the factor fixed in accordance with facts seldom form a common basis for mathematical calculation. To illustrate: The present award is not for 80 per cent of total disability, but is simply an award based upon 250 weeks, arbitrarily provided by statute for the arm loss and in addition an award for 30 per cent of 500 weeks *646based upon the finding that this naan’s “other cases” injury or disability incapacitated him 30 per cent oí his total ability, separate from, and without any regard to, any loss of such ability which may be attributable to the loss of the arm. This case does not involve facts requiring a consideration of the statutory maximum award, nor did the Eu-banks Case.
For the reasons stated, we find no merit in petitioner’s first suggested theory of calculation.
Petitioner’s second suggested method of calculation is based upon Magnolia Petroleum Co. v. Johns, 160 Okla. 221, 16 P. 2d 858, and other cases where the disabilities involved “specific” or “scheduled” members. Those decisions seem to be based upon the fact that the statute provides that the loss of any two of such “specific” members shall constitute total disability, and further provides that partial loss of a specific member shall be calculated upon a percentage basis. To illustrate: It is the thebry there that if one has a 10 per cent loss of each arm, the man has a 10 per cent loss of total, because the statute arbitrarily provides that the loss of both arms shall constitute total (unless otherwise shown). “Other cases” disabilities are not included in the enumeration of “specific” disabilities contained in the total disability provision of the statute and made an arbitrarily determined factor thereby.
For that reason the present case is not within the rules therein announced, but rather is determined by the rule of the Eubanks Case, supra, and others to the same effect.
We observe that the finding of the commission in the present case is to the effect that claimant sustained a 30 per cent disability to his back, and awarded 30 per cent of 500 weeks therefor. The parties in their presentation here would appear to assume that such finding is intended to mean that by reason of the back injury alone claimant is 30 per cent incapacitated. It would so appear to us, and we have so considered same.
We desire to point out, however, that this opinion should not be construed as holding that a certain percentage of injury to some designated part of the body within the “other cases” provision necessarily represents the same percentage of total disablement of the man.
Award affirmed. .
