Collection management and study of microscope slides
I couldn't find a reference to this publication in the "Specimens, samples and slides" forum, or the "REsources" forum, so thought it might be an interesting and useful addition. https://d-nb.info/1141357011/34 Collection management and study of microscope slides: Storage, profiling, deterioration, ...

Re: Mental struggles and microscopy
apochronaut wrote Interesting to read several of the well intentioned but glib comments. I can assure you that you have no idea how out of touch with reality they are.

Re: Mental struggles and microscopy
For quite a number of years now in my country, and I think in many, if not most western countries, mental health issues have been increasingly identified as a relatively common and serious area of concern, not just for the individuals affected but for society as a whole. There is growing concern abo...

Re: Staining techniques
Hi Antoni Glad to hear you are thinking of ordering the book; I think you'll find it very helpful. I should mention that the author, Eric Marson, operated a business called Northern Biological Supply (NBS) which sold slides and slide making equipment and supplies. So many of the reagents mentioned i...

Hi AntoniScott There are a great many references that could be given in answer to your question, but two that I would recommend are: Practical Microscopy by J. Eric Marson.

Ah, Bob. I'm afraid it will need more than a little polish! But I suspect the video will be very informative no matter what the language.

Re: Ilex leaf stem hand sections stained with Etzold FCA and Wacker W3ASim
I agree with deBult on the apparent differentiation, but I like them both very much. Very attractive images for such thick sections. I too would like a link to the video.

Re: Trouble with my stereo Barlow lens.
HI Greg I can't speak to the 2x Barlow, but I bought a 0.5x supplementary lens for my stereo scope to give a wider field of view, and increased clearance for large samples when needed. My scope uses a dovetail column rather than a round column, and so has a limited range of adjustment. I found that,...

Re: Stained histological sections
Very nice work Naphthalene. Very nice sections and images indeed. I'm assuming the triangular structure in each image is the section of the subcomissural organ? I had never heard of this before, and wonder if there are any hypotheses as to it's specific secretory function.

Thank you mrsonchus
These are quite a bit more informative than the previous "No Entry" signs Very nice to see the technique so well used on botanical samples, rather than the usual pond life studies.

Apparently eosin aqueous solutions are very prone to mould growth, so I suspect bacterial growth could also be an issue.
