I think you need to ask yourself why you are picking apart my answer??
A question was asked "What did they mean by..." and I offered an answer from a
19c text.
The combination I gave does produce Prussian blue. The "poison" cyanide
reference was related to the work I do with collodion. Interestingly, ferrous
sulfate was the Victorian antidote for cyanide poisoning because of this.
I have done cyanotypes, too. (Ferric Ammonium Citrate and Potassium
Ferricyanide). We also use lunar caustic and corrosive sublimate. :-)

The cyanide I was referring to is the poisonous stuff, and I use it as a fixer
for collodion.
