AbstractThe death of King Charles XII of Sweden has remained as a mystery for more than three centuries. Was he assassinated by his own men or killed by the enemy fire? Charles was killed by a projectile perforating his skull from left to right. In this study, we utilized a Synbone ballistic skull phantom and modern radiological imaging to clarify the factors behind the observed head injuries. We examined whether a musket ball fired from the enemy lines would be the most potential projectile. Our experiments with a leaden 19.5 mm musket ball demonstrated that at velocities of 200 to 250 m/s, it could cause similar type of injuries as observed in the remains of Charles . The radiological imaging supported the theory that the projectile was not a leaden but of some harder metal, as we could detect remnants of lead inside the wound channel unlike in Charles' case. In addition, our experiments showed that a 19.5mm musket ball  produces max. 17mm hole into a felt material  . The main evidence supporting 19.5 mm projectile size has been a 19-19.5mm bullet hole in a hat that Charles was wearing during his death. Additional experiments with a 25.4 mm steel ball produced approximately 20 mm hole in the felt. As our musket ball experiments also resulted in considerably smaller cranial injuries than those in Charles' case, we can conclude that the deadly projectile wasn't leaden and was more than 19.5 mm in diameter, potentially an iron cartouche ball that was shot from the enemy lines.

Natural mummification occurs in various favorable conditions. Cold environments have produced mummified human remains in northern Finland. These remains buried under the church floors mummified naturally probably through a process resembling freeze-drying. This chapter explores the conditions that led to the mummification of dozens and potentially hundreds of human remains. To conduct our study, we installed logging temperature and humidity measuring devices under the floors of three churches located by the shore of Bothnian Bay in northern Finland. Even our preliminary results show that the humidity and temperature conditions differ between these churches. It is also clear that relative humidity remains very high under the floors of each church. It appears that mummification has occurred in almost "cellar like" conditions. The preservation process was probably aided by the loose laid constructions allowing the air to freely move in the graves carrying the moisture from the remains.
