A practitioner took a scab from someone with a mild case, made an incision in the skin of a healthy person, and infected that person with the scab. Sheep-scab is a loathsome skin disease due to an acarian parasite.
I did find this link, but I don't think it will help out much, because there is nothing on the internet about it, other than this. http://en.allexperts.com/q/Wild-Animals-705/frozen-crab-life-thawed.htm. Or you can go to this link. Its about frozen lobsters coming back to life after thawed.
Pull the lobster out of the pot that it is cooking in with tongs. Hold it up in the air and examine its body. Notice its color. If the lobster is not bright red, throw it back in the pot to cook some more. Pull on one of its antennae or yank off one of its small walking legs. Both the walking leg and the antenna will come off easily if the lobster is done. Throw the lobster back in if the legs or antennae do not come off easily.
