For October and November 2010 we have opened a small exhibition in our main hall celebrating the diversity of fish found around the UK. These fish are all from our collections, with the oldest specimens going back to 1904.

To get these specimens usable for display we have had to do some conservation work. This has been as simple as cleaning the glass jar or Perspex display tank, to working on the specimen itself and changing the preservation fluid. How the fish has been preserved can affect its overall appearance and condition, but unfortunately whatever method we use the colour will be lost.

Many of the fish have been preserved in an alcohol solution, usually ethanol, which does result in shrinkage and the fish becoming very stiff. The preserving fluid can also become a very dark amber colour. This is due to materials such as lipids in the fish tissue being extracted out by the alcohol solution. However we know ethanol based preserving solutions work as the practice has been going on since the 1600’s! In more recent years we have found that it can also preserve DNA that is usable in modern molecular studies.

Another common preservative is formaldehyde, commonly called formalin. A diluted solution, usually of around 4% formaldehyde, has been used for over a century now. Formaldehyde causes chemical cross linking reactions in the biological tissues and this is termed ‘fixation’. Unfortunately formaldehyde does have problems, being pungent and potentially toxic to work with.

Some of the fish have also been preserved in a fluid called ‘Steedmans’. This is a mixture of propylene glycol (often used in anti freeze), a phenol (an aromatic organic chemical) and formaldehyde. This can preserve fish shape very well but there are concerns over its long term preservation properties.

For the main hall display all the preserving fluids were checked. All the specimens in formaldehyde and ‘Steedmans’ were moved to a safer alternative. This uses a chemical called DMDM Hydantoin which replaces the use of formaldehyde in everyday products such as shampoos and cosmetics and is much safer to work with.

Some of the specimens themselves needed some cleaning and tidying up. After years in a jar many had a build up of old proteins and fats on their surface. Other specimens had corrosion products on them from old metal tags that had been used for labels. Many of the specimens were also moved to more suitable glass jars.

The end result is an intriguing display highlighting specimens with fishy stories from the museums collections. The aim has been to make the specimens as accessible as possible so that visitors can get a close look at the preserved fish. The exhibition also represents the ongoing work that is required to care for the museums natural history collections for both now and the future.

Just found out that next week I'm going to be part of the team (is 3 people a team?) carrying out a baseline survey on all ten of the Civic Forum's members as requested by the Forum's funder. I'd been told to earmark 2 days to help out with this; have just come from a meeting outlining 5 days, including Saturday, travelling all around Lusaka and outlying towns and villages. Bit of a surprise to me frankly but fantastic opportunity to meet more people - especially people who don't work for NGO's!

Finally, finally feel like I've started work. I've spent hours in the back of a very hot car driving around a gridlocked Lusaka, a crash course (nearly literally) in NGO culture. But met some amazing people along the way though.

I wrote a press release and was very excited when the comms person from the organization we share offices with told me he'd take it to the journalist he was meeting that evening. Unfortunately, i hadn't counted for the dire network connection in our offices and lack of networked printer, so I couldn't get the press release to him, by hard copy or email. Not so exciting.

Then wrote a letter to the Minister for Finance and National Planning, an open letter we're placing in The Post and a letter to housing stakeholders inlcuding the World Bank. All part of our preparation for a crisis meeting. The Zambian government has published their Sixth National Development Plan, but left out the chapter on housing - madness if they want to deliver on their other priorities like health and education.

The Post is the paper with highest circulation figures, and very much holds the government to account. Unlike UK high-circulatin 'newspapers', The Post is crammed with political items, including a substantial international section. Not a celebrity in sight. How refreshing.

I think I'll be doing a lot of responsive stuff like this, as well as working on the longer-term strategy, but it's all useful as we talk a lot about voice, audience and tools.        

Yesterday we had our second toddler session in the gallery. We will be holding the sessions once a month and each month will look at a different theme - this month the theme was Autumn, and the one before looked at farm animals. The sessions are quite informal giving the little ones a chance to play and experience our different activities and to socialise with the other children. Another important part of the session is that it is bilingual, so the staff who are working (Ffion,Iola and myself this month) can speak in Welsh or English to the children, and the songs that Ffion led at the end were also in Welsh. It's a nice way for English speaking parents to begin to learn Welsh with their children.

So, what do we do? yesterday we had an art and craft table where the children could decorate pumpkin shapes or leaves, make leaf rubbings (although I find this is often a bit difficult for the under 3's!) or do some drawing. We also had a sensory tray filled with leaves, plastic bugs, fircones and dried lemon slices; coloured and scented playdough (yellow playdough was vanilla and the orange one cinammon and spices) with different cookie cutter shapes to play with; a sandpit and fircones (the sandpit was going to be our sensory tray and we were going to change it each month, but the children seemed to enjoy playing with the sand so much we didn't have the heart to change it! What I might do though is dye the sand at some point so it will be a little bit more exciting!); soft toys to play with and a quiet area with picture books. The picture books we had yesterday were 'Cwymp y dail' by Sian Lewis which is a Sali Mali book about Autumn, 'Cawl Pwmpen' by Helen Cooper - a nice autumnal book about pumpkin soup, 'Hibernation Station' by Michelle Meadows and Kurt Cyrus - an unbelievably cute story about animals hibernating, although perhaps a little too 'american' for some tastes (not mine!), 'The Tiny Seed' by Eric Carle - i love the illustrations in this, 'I am a Bunny' by Ole Risom and Richard Scarry - an adorable simple book about the seasons, and my find of the month, 'Autumn' by Gerda Muller - this was perfect for a bilingual session as it doesn't have any words (I didn't realise this when I ordered it) and consists of illustrations of the type of things that happen in the autumn - leaves falling off the trees, rainy weather, making leaf rubbings, making jam and hibernating animals. It's a lovely book to look through with a child as it lets them make up the story themselves.

We ended the session with a song about Autumn, and sent them all off with a leaf bag and a leaf spotting sheet in case they wanted to have a walk around the museum.

Next month our theme is buildings

Just met a journalist, who wants to do something with our story about the Government leaving housing out of the National Development Plan (which I still think must be an oversight?!).

He's taken our press release and he loved the open letter, and he's coming back on Saturday to do interviews. Result.
