This is a Cambridge Skin Temperature Meter that I rescued some years ago when the Physiology Department moved across town. These things were beautifully built works of art. I am guessing it dates from sometime in the 1950s. Does anyone have more information about the date these were manufactured?

Does the platypus have a stomach? The perils of popular science. Would respected science sources sex up their stories? My new paper just out. @jackdashby.bsky.social this is for you. meridian.allenpress.com/australian-z...

The comment from @absotively.bsky.social was clearly right, it is chart recorder paper. I think that the Y axis is probably decimal inches but the x axis is a time axis and it is not clear what the actual scale is. Because the photos are taken at an angle I can't really get an accurate ratio (thread

I feel I must point out that male echidnas also have a very similar venom gland even though it is not toxic and the spurs can't be used aggressively. More details in my paper

HELP! I was sent some photos of skulls on graph paper so I could get the dimensions. The x & y axes have different scaling. The y axis looks like inches divided into tenths, but the x axis has 6 divisions in the small rectangles. Is anyone familiar with this graph paper?

Following a brief Bluesy interchange about tawny frogmouths with @jackdashby.bsky.social I managed to find this picture of a nightjar I had seen years ago. They were called "goatsuckers", a libel started by Aristotle. The name looks better when the s is written as here in the old style medial s.
