    Abstract

    The authors have written this manual as a sequel to Mr. MacDonnell's work on the physical interpretation of bloodstain evidence, Flight Characteristics and Stain Patterns of Human Blood. The manual allows the nonscientist the opportunity to evaluate bloodstain patterns produced under known conditions and to draw his own conclusions. The results can be preserved as reference standards. There are twelve experiments as follows: (1) volume of a drop of blood, (2) spot size as a function of distance fallen, (3) effect of target surface on spatter, (4) spot shape versus impact angle, (5) effect of horizontal motion, (6) splashed blood versus distance fallen, (7) projected blood versus distance fallen, (8) “cast off” bloodstains, (9) medium velocity blood spatter, (10) high velocity blood spatter, (11) spot size versus horizontal projection, and (12) drying time of blood.
