Mr. Redlich. Did you also determine whether the elements barium and antimony are found in the .38 caliber ammunition manufactured by Remington Peters and Winchester Western, which was the ammunition used in the shooting of officer Tippit?
Mr. Gallagher. Yes; I did.
Mr. Redlich. And did you find that the elements barium and antimony were, in fact, present in this type of ammunition?
Mr. Gallagher. Yes; I did.
Mr. Redlich. With regard to the rifle cartridges, did you examine the cartridges which were actually found on the sixth floor of the Texas School Book Depository?
Mr. Gallagher. Yes; I did.
Mr. Redlich. And did you determine that the elements barium and antimony were present on those particular cartridges?
Mr. Gallagher. Yes; I did.
Mr. Redlich. Are you able to give us your opinion as to the possible effect of the washing of the paraffin casts on the analysis which you performed? Let me rephrase the question. Did the fact that these casts were washed prior to the neutron activation test materially alter, in your opinion, the results of the neutron activation analysis?
Mr. Gallagher. I can say that the washing did not remove all the antimony and barium.
