Well, I have the 4 issues of Vol 1 and would be willing to scan them in and send them to you. You would need to set some parameters for how this should be done as far as resolution, etc. Bill

Hi Bill, I could do that. It'll take a bit of time. It's when you want to do something like digitising the volumes that you wish you had a larger family and they could all do one number

Steve, What are the chances that you might digitize all the issues and stick them on one CD? That way people could get the full set. Bill

Following a request from a forum member for back issues of the Amateur Diatomist I have been through the box of remainder numbers. The following are available - again on a you pay the postage and send

This is indeed interesting. Thanks.

 Stephen, Thanks very much for your condenser tutorial andbook recommendation. I am enriched. I tried your experiment of the three stopswith the iris and found that as you say the 90% worked

Here's a photo of the setup that I have been using lately. It is very effective in keeping fumes to a minimum, and whatever fumes do get out are taken away through the opening in the cabinet's

Steve, Welcome to the group. I got into diatoms primarily through the influence of Robert McLaughlin, who gave me his diatom library (see:

Leszek, This is the very reason that I have not tried to clean diatoms with acids. When I was a young man (ages and ages ago- creak) my best friend, Dick Robinson, and I were into chemistry. It

When I first started cleaning samples I used a conical flask, on a tripod, over a bunsen. A 250ml conical flask to be exact. This was in an effort to reduce any potential for spillage and spitting,

Hello All, I've just joined the forum after thinking about it for a while. Actually the truth is that I've been a member of another forum group for years and I couldn't remember my password! Anyway,
