[Maltus' hand?:]
Take 3 flints about the bignes of hens eggs. When fyery hott quench them in whyte wines then strayne the wine &/ water it with syrup of MarshMallows & take it somwhat ordinaryly, & not only when you feele yourselfe distemperd with the stone. The Lord Brohell was helped with it.
Asmart, or lakeweed distilld as roses in a common still taken often especialy when you have any intimations of a fitt, and that liberaly for foureteene dayes at least least.    [Hartlib:] Mr. Maltus.
   In Latin Hydro-piper but it must bee of the right species there being three kinds or species of it.
   This Mr Maltus affirmed to have done wonders and perfect cures of the stone so that when the dead bodies were dissected there was found no signe of it. Of this also Mr. Boyle related wonders of Cures in Cornwall.

The famous Mr. Baxter was sadly troubled   
[60/4/20B]

with the Stone, and hee was cured by the constant taking of the distilled water of Arsmart or Lake-Weed (that has a little halfe Moone of black vpon the back side of it's leaves) for 3. Quarters of a year together every morning about halfe a pint at a time. My sister Broghil will readily send you the exact direction as hee tooke it. And who know's but God may have chosen some such base thing to doe that which all your great præscriptions have not beene able to effect. This is recommended to mee by this Experience and also because Dr. Boate did much recommend the same distilled Water for the same disease.
