RE: BRYONET: Hoyer's Solution & chloral hydrate


Dear Terry: I was also told as a student that Hoyers (chloral hydrate)
was carcinogenic. Under the "toxicology" for chloral hydrate the MSDS
states "Harmful if swallowed. Skin, eye, and respiratory irritant."
There is no mention of carcinogenicity.

That's all I know, but I am reasonably sure that's all that I need to know.

I think that some of those pearls of wisdom that we remember from our
student days are not unlike those we learned on our grandmother's knee.
Some of them you never forget and you always intuitively believe them,
whether or not they are supported by empirical evidence. And most of
them don't do us any harm.

Cheers, Allan (Fife)
