A Blast from the Past?

I stumbled upon a book in my attic the other day. It was published in 1985 and titled "Amphibians and Reptiles" (I'm not going to give the full name or author of the book for reasons explained later). Well I was reading through and of course noticed it was still use the one Triturus instead of the many genuses they've been split into now. As well as that, it had a little section describing a 'Siredon Mexicanum' and then went on to describe your everyday Axolotl. Not only that, it started going into different hormones/chemicals used to trigger metamorphosis and basically was telling you how to 'force' metamorphosise them. I didn't understand quite abit of what they were talking about, but it still seemed odd for your everyday person to be able to find out how to do this (if it's credible that is). Anyway, it was a very strange and suprising book, and reminded much how often these sorts of things are revised and changed.
I've decided not to give the full name or author just incase someone reads this and decides they want to metamorph their Axolotl and buys the book. Correct me if I'm wrong but it's rather sensitive information in my eyes.

Forced morphing? I've never heard that before, and I agree, it is interesting to see how scientists find new info and change a lot of things, although scientists probably still test hormones and things like that to see if they can speed up or slow morphing..I think I know what book you are talking about, is it a little book? I have the newer version.

I found a book similar, except it was on fish from like the 70's..It was pretty weird, there was a lot of things in the book that had different names today, and it showed how to force breed fish, but, nicely lol.
