branches into the interior of the spaces, and which by their anas- 

 tomoses constitute a rather loose plexus, in the midst of which in 

 some cases a central space is left. Among these capillaries and 

 in connection with them, and with the connective tissue of the 

 septa, is found an extremely close, but at the same time very 

 delicate network composed, if not exclusively, yet for the most 

 part of anastomosing cells ; and in the meshes of this plexus the 

 well known forms of Lymph- corpuscles are lodged. 



This fine network, was supposed by Eckhard to represent a 

 system of serous canals communicating directly with the blood 

 vessels. But Heidenhain, was unable to trace any communication 

 of the kind by means of injection, and Prof. His, has fully satisfied 

 himself, after numerous observations, that no such connexion 

 really exists. 



A minute account of the structure of the Thymus gland is 

 given, and the results of the author's and of Friedleben's observa- 

 tions respecting its functions are stated. Prof. His considers 

 that lymph- corpuscles are continually formed by the division of 

 the cell-like bodies contained in the capsules of the acini, and that 

 these corpuscles gradually find their way into the central canal, and 

 are conveyed by special canals into the lymphatics, and ultimately 

 into the blood where they are converted into red corpuscles.
