The incompleteness of His’s protocol might have been an harmless oversight. If not, then it can be done that he didn't want scientific competitors to repeat his procedure. It is also worth noting that Resin Processing & Embedding sectioning was The premise of his commercially successful models. Whatever the situation could be, we certainly don't plan to accuse such a fantastic scientist of any sleight of hand.
