Book excerpt: Excerpt from Text-Book of Forensic Medicine and Toxicology, Vol. 2 of 2 Appearance of blood stains - Methods of removing blood stains - Micro scopical examination - Spectroscopical examination - Other coloured stains. To say whether suspected spots are blood is frequently a matter that requires great care and experience in spectroscopic and microscopic examinations. The identification of blood stains not unfrequently furnishes an important link in the chain of evidence in a trial for homicide. It is a common practice when the garments of a suspected murderer are found with red stains on them to attribute the stains to the blood of some domestic animal or bird, or to spots of paint, dye, fruit stains, &c.
