Corrected entry: When Dr.Atherton determines to test the toxicity of the venom, he extracts a sample from one of the 3 tiny poison sacs on the (now) deceased spider. However, the distance he retracted the plunger on the syringe would have been sufficient to obtain 10-15 cc's, far more than the sac could hold.

Correction: So he drew air in after the venom was extracted. The syringe is not shown to hold 15 cubic centimeters of pure venom, so there's no mistake.

But when he injects the mouse, the syringe is pointing up. So, unless the syringe was full of venom, he would only inject air into the mouse.
