I believe John Locke spend much of his time between 1683-1689 in the Netherlands as he had fled England for being under suspicion of bad things.
As mentioned in another reply, this is indeed a Dutch pancake recipe. And the recipe does contain an 85 (or is 86?) in the top right corner. The addition of nutmeg, while very decadent, would have made sense when considering that Locke traveled between the cities of Holland, at that time the heart of the Dutch overseas trading empire. It spanned to such places as the island of Java, where you could pick the nutmeg right off of the tree.
