Order Only: Private Message to Sirius Black

[alt_severus]

Whilst I was working this afternoon, and thinking aloud, Miss Granger said something that prompted a realisation. I cannot call the page we were working from to mind closely enough: when speaking of the verbena, does the receipt call for "1⅓ʒ" leaf of verbena, or "1⅓fʒ" leaf of verbena?

If it is the latter, or could possibly be read as such: the author may intend for you to pulverise the leaf, and add only the juices.

Well, it was developed in about 1625 or something similar.

It's been copied so many times, though, I was sure somewhere along the line it had been updated for modern units of measure.

There's a set of apothecaries' weights in the shop. I'll pop down for them before I come back.

You needn't bring them, I know the conversions.
