Comparative observations made on various Coleoptera. The cylinder- 
axis of the nervous fibres which originate motion, on reaching the summit 
of the terminal layer, appears to divide into a greater or less number of 
fibrillae which are directly inserted in the intermediate disks, thus esta- 
blishing a direct connection between the muscle and the nerve ; and it 
therefore follows that there is no reservoir of nerve-force in the interior of 
the muscular tissue, which receives its nervous excitation direct from the 
cylinder-axis, as above described.
