Even given the disclaimer that "values are approximate," the equation 1 minim = 65 mL misses the mark by a factor of 975 (approximately). As the name might suggest, a minim was the smallest unit of liquid measure and was commonly considered to be about one drop.
Peer review indeed. Our peers should have peered more diligently!
