Variety. — Instead of passing to the thorax in the manner described, the 

 superior cardiac nerve may join the cardiac branch fiuTiished from one of the 

 other cervical ganglia. Scarpa describes this as the common disposition of the

 NeurologicEe." 



The Tipper cardiac nerve of the left side has, while in the neck, 

 the same course and connections as that of the right side. But within

 AND Nerves on the Left side. 



The full description cf this figure will be found at p. 558. The following numbers 

 refer to the sympathetic ganglia and nerves, and those immediately connected with 

 them :— 5, pharyngeal plexus ; 8, larj-ngeal plexus ; 13, pulmonary "plexus ; and to 

 the reader's left, above the pulmonary artery, a part of the cardiac plexus ; 24, superior
