There are "+" & "-" signs for zooming in & out. But even then, I think some parts were over-exposed during copying. Or the ink was wearing down by the time it was scanned? But yeah, the similarities are striking. I had to laugh in spite of myself when the Atemporator was invented. Simply put, it's a way to regulate fermenter temps in the early days. Tubes inside the fermenter carried warm or cold water to adjust the temp of the fermenting wort. I had to search a bit to find that. Sorta like finding the outer limits of online brewing knowledge/history. But the striking similarities caught me right off the bat while reading it. A bit more primitive equipment, true. but the processes are so similar as to be fascinating. I just never know what I'll find when researching my books. I'll come up with what I want to write next. Then research the details anywhere I can find them. This is one of them. I'm glad other folks enjoy this kind of thing now & then.
