	That sounds like a great way to teach such a course!  If I might
be permitted to make a minor pun, such a course really brings analytical
chemistry down to earth.  I hope you both enjoyed the course and derived
benefit from it.

	A minor digression...  Just for the hell of it, several years ago
I ground up several pounds of dried catnip in a Wiley mill, and proceeded
to isolate the active ingredient (nepetalactone) using a bank of Soxhlet 
extractors.  I had almost 100 gm isolated and was undergoing further solvent
purification in a rotary evaporator, when I managed let the rotary evaporator
flask roll off the bench onto the floor.  I've often wondered what would
happen if I brought one of my cats to my lab (most of the material ran
under a fume hood base cabinet - where it still resides)... :-)

	Well, I'll tell you something which puzzles me.  In the past week
since I wrote my articles on aloe, I checked no fewer than eight reference
books in my organization's library on pharmacy, pharmacology and pharmacognosy
and I can find *NO* reference that aloe has any recognized medical use
other than as a cathartic.  As an example, I not only checked a current
Remington's, but I looked in a 50-year old Remington's (which contains a
wealth of information on natural products).

	One would think that if aloe had any real healing effect on burns
it would be mentioned in Remington's or the Pharmacopeia/National Formulary.

	Hmmm...
