At a recent gossip (Prof) Fred Price showed some beautiful and intriguing slides. Fred is currently cataloguing the collection of the Buffalo Museum of Science, and the two injections belong to this collection.

The top picture is of a fossilised ammonite

I find the next picture down particularly interesting: most of us have seen fine preparations of diatom frustules, but this is the first time I have seen a picture of diatom in situ in this case on a piece of red (rhodophyte) sea-weed. I some cases only the bottom of the valves have been left, but in many cases the full diatom is shown, and some detail of the top frustule are clearly visible.

The next two slides are from the Buffalo Museum of Science collection. As a cat-lover I have mixed feelings about both of them! But the top one is a transverse section of a cat's foreleg; and the second a longditudinal section of a cat's jaw.

I regret due to my own carelessness the lighting is not as even as it should have been, but I think the quality of the mounts still show.
