—I regret to say that we involuntarily overlooked Dr. Trzcińska-Dabrowska's communication which first appeared in the Index Medicus in August 1969.We must certainly give full credit to Dr. Trzcińska-Dabrowska and co-workers. Any further reprints that we send will have a note mentioning their papers.
