Use the search engine. We have discussed Legard's books at length. Some of the past discussions are valuable & will save some grief & wasted
effort.
Some of the material IS valid but the citations are terrible and often the patents are wrongly numbered. SOME of the synthesis are just plain
bullshit. The copper fulminate lab is a great example. Basically, one needs to work through that book to determine what's usable and what's bullshit.
That in itself is a scary agenda.
I have compared edition 2 to edition 3. Legard is obviously aware that he was sloppy; but edition 3 is no prize winner either. It appears to be a book
written by an educated man who has a wonderful lab at his disposal and simply was sloppy when it came to writing....OR he had the worst editor on
God's Green Earth.
