Granted. Ruling of the court of appeal is reversed. La.Code Civ.P. art. 1464 is not applicable. The ruling of the district court, denying plaintiff’s motion to quash, is reinstated. However, the trial judge is instructed to issue a protective order to insure the integrity of the specimens, and to limit to a reasonable number, within his discretion, the number of experts who may be permitted to examine the specimens.
