During the extraction of trimyristin from nutmeg, two students were given different samples of nutmeg. They noticed that one sample was very fragrant with the characteristic odor of nutmeg, while the other one looked old and was not very fragrant at all. When they asked their instructor about it, she told them it would be OK to proceed with both samples. Still skeptical, they performed the experiment and compared their results. It seemed that here was not much difference: they had approximately identical quantities of the isolated product, with almost identical melting point. Please explain.
