Mr. Day. When the sack was released on November 22 to the FBI about 11:45 p.m., I put further information to the FBI reading as follows: "FBI: Has been dusted with metallic magnetic powder on outside only. Inside has not been processed. Lieut. J. C. Day."
Mr. Belin. Did you find anything, any print of any kind, in connection with the processing of this?
Mr. Day. No legible prints were found with the powder, no.
Mr. Belin. Do you know whether any legible prints were found by any other means or any other place?
Mr. Day. There is a legible print on it now. They were on there when it was returned to me from the FBI on November 24.
Mr. Belin. Do you know by what means they found these?
Mr. Day. It is apparently silver nitrate. It could be another compound they have used. The sack had an orange color indicating it was silver nitrate.
Mr. Belin. You mean the sack when it came back from the FBI had a——
Mr. Day. Orange color. It is another method of processing paper for fingerprints.
Mr. Belin. Was there anything inside the bag, if you know, when you found it?
