FOGG MUSEUM X-RAY EXPERT MAY DECIDE NEW YORK TRIAL

A Harvard X-ray expert, making use of a system of identifying paintings which was originated and developed by the Fogg Art Museum, is likely to prove the deciding witness in the $500,000 art trial which has been waged in New York for the last four weeks over "La Belle Ferronniere."

Yesterday morning a witness testified that there was in the possession of the Museum here an X-ray picture of the Louvre copy of the disputed painting. Supreme Court Justice Black, desiring to hasten the conclusion of the case, urged that an air-plane be dispatched to bring the negative to New York, where, by a comparison with Mrs. Andree Lardoux Hahn's copy, it might decide which is the original.

To obtain permission to submit the Fogg picture as evidence, it was necessary to call up the Louvre Museum in Paris by trans-oceanic telephone. At 1 o'clock the important negative left Boston, and will be offered today by Alan Burroughs '20, X-ray expert and head of the identification department at the Fogg.
