Excellent! Here I was grunting away with Herculean effort to make this 
work (hunting out my Merk CD was the first step). However every time I 
get around to using any chemistry, my memory of it has slipped to the 
wayside. Thanks much!!  Now I can go back to being a mental lounge 
lizard again. Off to get some distilled water....(no distiller... dammit).

Speaking of which, anyone know a good chemistry textbook that I should 
keep my eyes open for at used book sales and the like? It would have to 
be Canadian, as I doubt I would come across many southern school texts 
here.  It would have to spell out the basics in human speak, then shift 
gears to keep me interested.
