BIG - Here's my understanding of the math: the 2.5cc is the amount being
ingested by a hypothetical ferret, not by a 150# human.
 
The human is assumed to be taking 1 tsp/day =  4.921 cc. An equivalent dose
proportionately for the ferret would thus be .0656cc, or 4.921cc / 75,
because a 2# ferret weighs 75 times less than a 150# human.
 
If, instead of taking this small amount (.0656cc), the ferret is taking 2.5
cc, then the animal is taking 2.5 / .0656 or 38.1 times as much CS per body
weight--meaning the ferret taking 2.5cc is ingesting roughly 40 times more
colloidal silver per pound of body weight than the human taking 1 tsp/day.
The bottom line is that this is more than a whole order of magnitude
greater, proportionately, than what humans are consuming.
 
[Moderator's note: Yes..  I was calculating on basis of human getting
2.5cc, not 5cc as note said.  You're right.  BIG]
