Lysozyme

I was impressed by this model of something called lysozyme in the museum in the basement of the Royal Institute in Albemarle Street yesterday. However much work must have been involved in elucidating such a structure before modern equipment was available?

Sadly, I did not find a sign which told us. But there was one which told us that the stuff was found in various bodily fluids, such as spittle and mucus.

Now I wonder whether the Royal Institute people got it right. The two pictures offered at the wikipedia entry look very different - but I suppose you have to be a chemist to be able to expect to understand it all. On safer ground with the miners' lamps, said to have been invented on the premises.
