Nettle-leaved Bellflower (under the box woods) and Clustered Bellflower (in the chalk grassland at the top), still flowering, on Box Hill.

Interesting bellflower seed heads too #wildflowerhour

October 2025: 16,046 files released at the National Archives, three-quarters of which are WW2 WO records (how many still to go?!)

Lots of FCO files on Hong Kong from 1995 (two years before handover, so a busy time)

But which new file from August-October 2025 looks most curious…?

September 2025: 14,749 files released at the National Archives, again lots of WW2 War Office records.

Also hundreds of MoD local maps of Northern Irish towns and borders, from 1969 onwards.

Plus thousands of born-digital Land Registry docs, including this excitingly self-referential one

August 2025: 16,013 files, 6095 of which are WW2 War Office personnel files, plus thousands of defunct company records, the oldest dating from 1864:

I’ve been catching up working through all the titles of files released at the National Archives, August-October 2025

Here are the overviews followed by a vote for what might be interesting to look at and report…

Any suggestions of good STS scholarship (journal articles, book chapters, other) on disability and technology? never been quite satisfied with ones I've used before in teaching...

I did not know that. Thanks!

That’s the end of this, ahem, long synthetic 🧵of things I’ve seen at the British Textile Biennial

Credit to all the inspiring work of curators, artists and teams behind #btb25

5) also at Haworth Art Gallery: a room of Ivan Forde’s works. He’s from New York, and does frankly amazing things with cyanotype, using materials repurposed from marine waste with Bionic Yarn

180 years after Anna Atkins, a link that is implied rather than made explicit

Terylene was also marketed at men

Knife-edges on ledges!

A rave on the ocean wave!

Here’s me, 1977, wearing Crimplene trousers (stars? flowers?) looking into a pond in a wood outside Stevenage

(I still look into ponds quite a lot)

You may, if you are of a certain age, react nostalgically to the Terylene and Crimplene sample designs and colours

These are from Lancaster printers Standfast and Barracks, mid-1960s

“Who says a girl’s a tender flower
You won’t find us in an ivory tower
Breakaway girls don’t stay home with the chattels
They’ve got Bri-Nylon to win their battles”

(“Bri-Nylon” = British Nylon, another patriotically branded synthetic fibre. This time associated with, um, Norman invasion?)

Lots of interesting objects.

Here’s Ermen and Roby’s Terylene sewing thread

(Ermen & Roby used to be Ermen & Engels.

Engels as in Friedrich Engels)

And for ICI it is unashamedly about OIL and MODERN BRITAIN

Right: ICI educational posters, ‘Terylene a great British discovery’ and ‘Britain turns to Terylene’, 1956

New Elizabethan, “defiant modernism”(©️Science Museum) vibes

Patented as Terylene (and in fluffed up form as Crimplene) it is made and promoted by ICI as the last word in modern fabrics.

Here’s Terylene fibre being made, in a glorious expression of modern production at ICI Billingham. (Photo by Walter and Rita Numberg)

Whinfield and Dickson work at the research department of the Calico Printers Association at Broad Oak Printworks in Accrington

It had been a site of 18th/19th innovation, so immediately this discovery is read as resurgent Lancashire industrial invention

“Englands bread hangs by Lancashire thread”

One more story: we’re going to Haworth Art Gallery in Accrington for the Terylene story.

Rex Whinfield and James Tennant Dickson make the first polyester fibres in 1941. Nice to see an early sample, on loan from the Society of Dyers and Colourists

unexpected wrapped musical instrument morbid theme!

(L) Throup’s worsted wool moulded modular sousaphone case from ‘The funeral of New Orleans’

(R) a shrouded ophicleide, on a monument erected in 1860 by members of the Accrington Brass Band to the memory of one of their musicians, Adam Westwell

3) on to the installation of Aitor Throup’s designs

all in a ruined cinema in Burnley

Enjoyably atmospheric and pretentious

Third Biennial exhibit at Queen Street Mill Textile Museum was a multi-media thing - film of Balbir Singh dance company dancing with fabrics and digit-y dots, projected on to more fabric so you get receding images. Dir. Tim Smith

Very good.

Here’s a snippet, not the best bit, but gives the gist
