When you put water into a ſeething Balneum wherein there are glaſſes, let it be hot or elſe thou wilt endanger the breaking
or the glaſſes.
9.
When thou takeſt any earthen, or glaſſe veſſell from the fire,
expoſe it not to the cold aire too ſuddenly for feare it ſhould break.
10.
If thou wouldeſt have a Balneum as hot as aſhes,' put ſand or ſawduſt into it, that the heat of the water may be therewith kept in, and made more intenſe.
11.
If you would make a heat with horſe-dung, the manner is this, viz. make a hole in the ground, then lay one courſe of horſe-dung a foot thick, then a courſe of unſlaked lime halfe a foot
thick, then another of dung, as before, then let in your veſſell, and lay round it lime, and horſe-dung mixt together; preſſe it downe very hard; you muſt ſprinkle it every other day with water, and when it ceaſeth to be hot, then take it out and put in more.
12.
Note that alwayes ſand or aſhes muſt be well ſifted, for otherwiſe a coal or ſtone therein may break your glaſſe.
13.
The time for putrefaction of things is various, for if the thing to be putrefied be vegetables and green, leſſe time is required, if dry, a longer, if Minerals the longeſt of all. Thus much note,that|things are ſooner putrefied in cloudy weather then in faire.
14.
If thou wouldeſt keep vegetables freſh and green all the year, gather them in a dry day, and put them into an earthen veſſell, which you muſt ſtop cloſe, and ſet in a cold place: and they will as ſaith Glauberus keep freſh a whole year.
