need help concerning anaesthesia in in vivo experiment

[Cecchrelli Francesco]

Dear Agnes,
chlorale hydrate is a very easy to handle anesthetic for animal 
experiments.
I use them in rat experimentation very well.
In rat, 400 mg/kg i.p., anesthetized the animal for 40 min.- 1 hour.
Second dose is 200 mg/kg i.p.
