Just in case you don't know, water breathing items allow an amount of troops limited by size, not number, which is probably why you are confused regarding Manual of Water Breathing.
What the (game) manual meant was that the manual allowed a total of 50 size units, which would make 25 size-2 units (size-2 is human size)

Thanks a lot. Now I do understand. My giants don't tend to be size 2.
