(Abstract.) 



The author has re-examined the lung of the frog with special 

 reference to its nervous apparatus. Arnold, several years ago, gave a 

 description of the nerves of the frog's lung. Amongst the nerve- 

 fibres he found bell-shaped nerve-cells provided with a straight and a 

 spiral fibre. He was unable to find any nerve-cells in the apex of the 

 lung. Kandarazki has more recently examined these nerves. He 

 was unable to find any trace of a spiral fibre in the nerve-cells, and he 

 considers the appearances which have been figured as such, to be due 

 to folds in the capsule of the cell. After giving an account of the 

 methods used for exhibiting the course, relations, and structure of the 

 nerves of the lung, the author gives an account of the result of his 

 observations. 



The pulmonary branches of the vagus enter the lung at its root 

 or near its attached end. The branches contain medullated and non- 

 medullated nerve-fibres, and amongst these fibres before they enter the
