|Description||Draft articles and notes relating to experiments which Norris described as 'segment' experiments and experiments on spinal cord. These experiments primarily involved the decapitation of frogs and other animals to analyse 'muscular irritability' (movement of the muscles). Notes on 'anaesthesia' experiments are also included, in which movement and other effects on animals to which poisonous gas had been applied were analysed.|
Norris published an article relating to this work entitled 'Researches on muscular irritability and the relations which exist between muscle, nerve and blood' published in the Journal of Anatomy and Physiology, Volume 1 Number 2 (1867) pages 217-236. Norris' paper 'On Stasis of the Blood, and Exudation' published in the 'Proceedings of the Royal Society of London' Volume 12 (1862-1863) also relates to his segment experiments.
