In the first half of the ms., THU and TT used R{ecipe} to render Rx. CAG and PHS used unicode Rx. @thuchacz @TillmannTaape please search for this and use the unicode in all three versions.

43r, 48v, 50r.
note that in 48v I changed:
<ab>Take one <ms>lb</ms> of <m>antimony</m>, <ms>half a lb</ms> <m>black soap</m>, and <ms>half a lb</ms> of <m>tartar from <pl>Montpellier</pl></m>.
to
<ab>℞ one <ms>lb</ms> of <m>antimony</m>, <ms>half a lb</ms> <m>black soap</m>, and <ms>half a lb</ms> of <m>tartar from <pl>Montpellier</pl></m>.
idem in 50r:
<ab>Take a <tl><m>glass</m> ampul</tl> with an opening capable of receiving <pa>cherries</pa> ...
to
<ab>℞ a <tl><m>glass</m> ampul</tl> with an opening capable of receiving <pa>cherries</pa> ...
