The Identification of Seminal Stains. 833 aqueous solution of methyl green is then poured on and gently heated over theflame until it steams. It is again washed, dried and mounted on a drop ofCanada balsam dissolved in xylol. The preparation thus obtained is perma-nent, can be examined with the highest powers of the microscope, and ex-hibited in court, if necessary. When entire, well-preserved spermatozoa are found, there is no difficulty intheir identification. But when the stains have been dried for some time, it isusually difficult to obtain such ones, for the heads are then very easily brokenoff from the tails. And in an unstained preparation, the former can easilybe mistakened for spores, or vice versa, and the tails are almost invisible fromtheir smallness and transparency. With the method above given, certain dif-ferential characters of the head can be made out which leave no doubt as totheir identity. Its composition is stated in the books to be of the same char-acter as the n
