It is very injurious to wrap these delicate specimens in cotton before sending them by mail or express. A perfect method is to place the preserved specimen in a bottle filled completely with alcohol, thus imitating the condition of a fetus in utero. If there be no air or cotton in the bottle, it is almost impossible to injure the embryo by shaking it. Very sincerely yours, Franklin P. Mall, Professor of Anatomy, Johns Hopkins University.doi:10.1001/jama.1897.02440090045013 fatcat:qthuxukxnzfvrfqolgzapfct3y
