Just before we open the general discussion, Father, may we have to ask the doctor one or two questions which have been rather general that we've heard before. Of course, I'm kind of paranoid too. My psychiatrist says I'm paranoid, but that's just because he hates me, you see. We want Dr. Offer to answer two questions first before we throw this open to general discussion because so many people have asked this. How do you get a hold of the HOD test and what do you do about the MOD test? Will you tell us this, Doctor? Thank you very much. The HOD test is available from a manufacturer in Toronto. I think in the communication to AA Doctors at the back, you'll find that the name Gilbert and Company, as the sources apply for Niacin in Canada, is the same fellow who sells the HOD test. And with the kit, he includes the Journal of Neuropsychiatry, August 1961, where we publish the details of not only the HOD test but also the chemical test. The chemical test is very easy and any competent technician can learn to do it in one or two days provided the instructions are followed. As you know, when you repeat chemical work, you've got to do it the way the first man did before you produce a modification. Just a few weeks ago, a chemist in Toronto decided to repeat the test and I had said to his superintendent, if he can't make it work, send him out to Saskatoon. So he ran 30 specimens and couldn't find anything. So he came out to Saskatoon and within one hour we discovered what he'd done wrong. We had said in our method, analyze fresh specimens within three or four hours. They had drawn the specimens and left them on the ward three to four days and then taken them to the lab for analysis, the way you do with sodium. And so they couldn't find anything. So it's very important that the details are followed. Now, any one of you can start to use the HOD test without any difficulty. It's very easy and if you have any questions, I'd be happy to send you more information. If you have labs and want to do the Malbaria test, I suggest that you send your technician up to us for a day or two and…
