Nope!  Manitou.  As in Manitou Springs, Colorado!  Nolit misprinted.

It only takes one bottle to spoil a bunch.  These were not manufactured 
to Tesla cap specs but as common water bottles.  They varied from bottle 
to bottle.  This was Tesla's weak link.  R. Hull

I was refering to the tank levels,  not the bottle levels for 
evaporation.  Tesla notes this evaopration problem as particularly 
bedeviling in a number of private communications to Scherff and Johnson. 
 Leland Anderson,(greatest Tesla Historian), is in possesion of an 
amazing amount of original and personal Tesla material and documents 
which have never seen the light of day!!   He has made a small amount of 
it available to me with the promise of not releasing or publishing it 
prior to his own revelations.  You would not believe the amazing 
character of some of it.

I just recently in a post on dielectrics mentioned that bottle/glass was 
a pretty fair dielectric.  The problem is, most amateurs never secure the 
right type! (They evidently don't have the resources or the time to even 
get the correct bottles!!)  Thus, their efforts fall short of even the 
mediocre mark.  This is what has seemingly given the bottle capacitors 
and glass caps, in general, a rather bad name.  It would be equivalent to 
saying plastic capacitors are no good because only the common mylar was 
used as a capacitor by all novices!  There are lots of plastics and lots 
of glasses.  R. Hull
