“Lays eggs on larva boring in wood.” Add just one comma and that comes across as harsh criticism, but it’s really meant as a compliment.
This is from an illustrated fact-sheet of Beneficial Insects that I found in the Biodiversity Heritage Library. It’s a poster from the WWII era that might as well be labeled “THESE ARE YOUR FRIENDS. DO NOT ATTACK THESE INSECTS.”
As propaganda, I suppose it’s still pretty effective. At least I found them all rather handsome – but none…
Science Art: Hypocaustum excavated behind the old city of Rottenburg am Neckar , by Eduard von Kallee.
An ancient Roman central heating system – hot water would be flooded through the basement, and the floors would warm up. “Hypocaust” was the name of the system. This particular one, painted in 1884, was built in the city of Rottenburg am Neckar, which the Romans called Sumelocenna when they lived there. The city might have gotten its “rotten” name because of an earlier version of the word “rotten,” which also meant “ruined” – the Germans built their city over the ruins of th…
Science Art: Four views of the Alvan Clark & Sons workshop..., from Scientific American, Sep. 24, 1887
Here, an astronomical family is building a 36-inch refractor telescope known as the Great Lick Refractor in the 1880s. It’s named for James Lick, an eccentric entrepreneur who financed the observatory. Please, don’t lick the telescope.
The lenses were fabricated in France, then shipped to Boston where Alvan Clark and his sons ground and polished the glass, built the telescope to house the lenses, then set them in place in a new observatory in Harvard College. They had to wait to put the fini…
A bird in its home (grown on a vine, fashioned by humans).
Cute little guy, too.
I found this on the Scientific Illustration tumblr, which got it from the Cincinnati Public Library’s copy of Illustrations of the nests and eggs of birds of Ohio.
Apparently, the book started as a kind of by-subscription service, like a bird-watching newsletter, but then was bound together and published as a guide.
Seems like something people still do today, I suppose. Only more …
This image is from the British Library archive, a book called The Cruise of the Marchesa … With maps and … woodcuts drawn by J. Keulemans, C. Whymper and others. by Francis H. H. Guillemard, a medical doctor who decided to explore New Guinea (and the Malay Archipelago) rather than settling down in Kent to practice medicine. Then, Cyprus. Then, Morocco. Then, Cambridge, where he became geographical editor of the Cambridge University Press.
The book says this about the korowaar:
SONG: “My Batteries”.
ABSTRACT: This song was kind of a no-brainer. (I couldn’t afford more, the weekend I’ve had – sick day, plumbing emergency, surprise bulldozers removing part of my back yard….) I mean, it’s not literally a moment of silence. It is using a technique I used more than a decade ago to put a six-word…
Some researchers wear their subjects of study underneath their sleeves. I quite like the octopus….
from The Modern Practice of the Electric Telegraph, 1881.
