On the question of the forensic significance of the Beccadelli test

Abstract

The issue of differential recognition of blood is the most urgent for forensic medical examination. Attempts to resolve this issue are not new - back in 1828, Barruel tried to distinguish between human and animal blood by the specific smell that blood supposedly emitted when sulfuric acid was added to it. This smell is characteristic of every type of blood; so, during this treatment, human blood gives off the smell of human sweat, horse blood - horse manure, etc. Some researchers used this sample as early as 1881 (Dragendorf), despite the fact that Barruel himself admitted that his method did not have a strict accuracy.
