Pournelle and Mackenzie on preserving civilization

From scifi author Jerry Pournelle in the March 1983 number of Survive magazine:

Probably the most valuable book I own is MacKenzie's 10,000 Formulas. Published in 1868, it has 400 pages telling how to make everything known about at the time. The section on medicines is useful only for amusement, but MacKenzie shows how to butcher animals, smoke and preserve meat, make soap, gunpowder and fireworks, and how to brew beer–from choosing the barley and hops to malting the barley ("Throw the malt up into a heap as high as possible, where let it lie till it grows as hot as the hand can bear it, which usually happens in the space of about 30 hours"). Alas, nothing else like MacKenzie's book seems to be available.

Here's a link to the Google Books copy of Mackenzie, along with its magnificent subtitle:
