As pointed out in ny letter of Mareh 3, 1944, the eontract terminated officially oa February 15, 1944, but the investigation voald bo continued without charge until June because the original oxporinaats wore started late. Since o eneck was received vaicn took ear* of the subsidy up to loveaber 15, 1947, there ia duo on the old oaatract th* h of |1,250. for the final quarter of the contract (fra levember 15, 1947 to February 15, 1944). V* have delayed sending an invoice for Lie final quarter mtil all work could bo finished and a final report submitted. Following th* termination of the experiment in Juno, it has required several months to do the histological work, study tas tissue sections, collate th* data end prepare the report which aeccmpanlee this letter.
