It has now been about 5 months since the manual went to press. During that period I found some minor editorial errors that can easily be corrected by the new user. More importantly, I recently started teaching a class at Washington Adventist University that meets on only two consecutive days per week. This is very different from my previous situation at St. Anselm's Abbey School because the equipment available to me is not the same and I don't have the benefit of seeing my students on a daily basis. Consequently I made some major adjustments to some of the lab procedures in order to adapt. Since everyone's situation is different I want to share this information with you now. I will try my best to post those updates about every 1-2 weeks. Eventually I will incorporate them into the next edition.
