A Fellow of the Royal Entomological Society, Harold Edward Hammond, (1902 – 1963), was a keen Lepidopterist. Coupled with this affinity for butterflies and moths he was also interested in entomology generally and would take up a new order every couple of seasons, afterwards giving the carefully mounted specimens to some young aspiring student of the subject. Before his health failed a few years before his death, it was not unusual to find Hammond out in the snow on Boxing Day, splitting logs with an axe to find beetle larvae. Generous, almost to a fault, he was content with gaining new knowledge and found reward in encouraging a new generation of enthusiasts.
Hammond’s main focus was on the larvae of Lepidoptera and, as can be seen by the associated article, he became an expert in their preservation. Raising many larvae into a suitable size for mounting could be somewhat problematic, so his Birmingham garden became a cross between a sanctuary and a fattening pen for many caterpillars. This miniature farm was orderly and well maintained, where trees were pruned to the size of bushes for easy access and micro habitats were constructed to help manage conditions for more demanding food plants.
The skills that Hammond developed in preserving caterpillars were much in demand by fellow entomologists, and he would sometimes receive dozens of boxes of live larvae a week, all dutifully delivered by a postman oblivious to their wriggling contents. His fee for this service was a request that he could have a larva or two for his own collection. During his preparations he encountered many parasitic hymenopteran and dipteran larvae, so he became quite the expert on those also, co-authoring several papers in the Entomologist’s Gazette.
Katie Ott, a museum studies student on placement with the Horniman, tells us about her fascinating work with our botany collection.
I’m Katie, and I’m three weeks into an eight-week work placement at the Horniman, helping the Natural History team to research and document the botany collection.
The botany collection at the Horniman is made up of around 3000 individual specimens either mounted onto herbarium sheets or bound in volumes. The flowering plant collection dates mainly from 1830-1850.

The main task is to transcribe the (beautiful, but squiggly) Victorian handwriting on the herbarium sheets such as the plant’s scientific name, and where it was found etc onto MimsyXG, our collections management database.
I was just thinking last week that social media has taken over the world as the most thing in existence, corporeal or not, when this article came out about how scientists should all be trained in its use; Social Media; More Scientists Needed. No hope of escape for any of us then. (I say on a social media platform).
Last Wednesday, sadly, New Walk Museum had items stolen from display; From Rhino horns to Egyptian jewels. Whilst the objects stolen last week weren’t of natural history origin, this article (if you can see it through the adverts) also reveals that rhino horn was stolen from there a few years ago. The huge rhino horn problem faced by museums, primarily in 2012, was largely curbed by museums removing all horn from display. An update on this situation was published on our website recently in Rhinos and Museums.
For over 2000 years, rhino horn has been used in Traditional Chinese Medicine to treat a variety of ailments including fever, headaches, and vomiting. It is typically ground or shaved and then dissolved in boiling water to drink. Rhino horn is solely comprised of keratin (as are your finger nails) with a structure more similar to a turtle’s beak or a horse’s hoof than the mass of compressed hair as it used to be thought. Keratin in really vast quantities may be able to detect some poisons, but absolutely not in a practical sense, and it certainly doesn’t have the ability to cure any of the vast number of illnesses listed in the ‘TCM handbook’.
Trade in modern rhino horn, and unworked antique pieces that predate the 1947 legislation, is illegal. Unfortunately the demand for horn is high and things like its legality don’t currently seem to be enough to deter the market. Poachers are turning to more sophisticated, and nefarious, techniques to obtain it.

In South Africa, where the highest numbers of wild rhino live, poaching went from 13 deaths in 2007 and 83 in 2008, through 448 in 2011 and 668 in 2012, to a peak in 2014 where 1215 animals were killed for their horn. Since 2015 the number of rhinos killed per year has dropped slightly, largely due to an increase in security and protection in their range states, however the rate of slaughter is still alarming (1054 were poached in 2016 in South Africa alone) and conservationists fear the day that the number of deaths will outnumber the births, and the African rhinos will go into decline. Both African species are still trying to recover after intensive poaching during the 20th Century decimated their numbers, but are (were) recovering due to intensive conservation management. That is until the last decade and the current ‘poaching crisis’.
In a move unprecedented in Specimen of the Week history, I have chosen to blogify the same specimen as I selected in my last Specimen of the Week. The reason is that in many ways it is not the same specimen as it was six weeks ago: it has undergone a profound transformation. We used to call this specimen “the googly-eyed owl”, due to its comedy wonky eyes, but it is googly-eyed no longer. This week’s Specimen of the Week is…
Tell us about your day job: I am a specialist natural history conservator, working for a museums service and my own business. In both, I provide conservation services to the heritage and private sector. This is mainly in the North West – everywhere from Cumbria or to Cheshire, but my work has taken me all over the country which means I get to visit lots of new collections.
My role covers all scope of natural history collections but I specialise in bone, fluid preserved collections and taxidermy. My work is incredibly varied; as well as a conservator I am a preparator – preparing bone, skins, taxidermy and fluid preserved material. I can spend 200 hours plus conserving a single specimen, or carry out a whole collection survey in 72 hours! I also provide training to institutions in natural history collections care.

Natural science collections are very popular with visitors. Why do you think this is?
Overall, I think it is about innate curiosity – the natural world is deeply fascinating and diverse. The reason natural history collections are popular with children is they are still in that stage of uninhibited curiosity.
This year’s event (#NatSCA2017), at the University Museum of Zoology, Cambridge, had a record 110 delegates, and as such was the biggest NatSCA conference to date. At the heart of the conference was the new Whale Hall, part of an enormous redevelopment project of the David Attenborough Building. As many of us marvelled at the huge leviathan overhead, the rest of us rushed between advertising sponsor stalls, exchanged ideas, caught up with one another and most importantly, fuelled up on coffee!
Feeling inspired, we were ready to begin this year’s talks on the theme: “Evolving Ideas: Provocative New Ways of Working with Collections” as Paolo Viscardi, NatSCA Chair, keenly ushered us in to the main lecture theatre. Continue reading →
