slashed the bite accidentally while shaving. It became infected and blood poisoning resulted. Recent laboratory studies have revealed that some ancient mummies do indeed carry mold‚ including at least two potentially dangerous species—Aspergillus niger and Aspergillus flavus. These molds can cause allergic reactions ranging from congestion to bleeding in the lungs. The toxins can be particularly harmful for people with weakened immune systems ("Lord Carnarvon’s death‚" 1923‚ p. 25). Some tomb walls
