Intrinsic Nerves of the Kidney.^ 



The following conclusions were reached: "That the renal 

 nerves enter with the vessels at the hilum, and that with their multi- 

 farious ramifications and ganglionic enlargements they form a not in 

 considerable portion of the kidney's entire substance. From the vas- 

 cular nerves — which we may call the primary ones — come secondary- 

 divisions, distributed throughout all the cortical and medullary-cortical 

 regions in the form of a vast open network. That the glomerules are 

 surrounded by a wide meshed plexus of fibres having terminal and 

 end-knobs approximated closely to the Bowman capsule, but that no 

 finer nerves can be seen penetrating that membrane ; and end-termin- 

 ations within the capsule upon the convoluted vessels, either in the 

 form of knobs, or in the finer pointed terminations cannot be discov- 

 ered. That fibres piss off singly and separately from the vascular 

 nerves, and are distributed on the convoluted tubules, not only with 

 end-terminations in the form of the well-known globular ending, but 

 also in fine, delicate threads that penetrate the membrana propria of 

 the tube and presumably enter the cement substance between the epi- 

 thelial cells, and that the function of these divisions to the tubuli con- 

 torti IS probably one concerning the urinary secretion. Lastly, that 

 ganglionic enlargements occur widely, but that, strictly speaking, no 

 nerve cells provided with nucleus, body, and protoplasmic areas are to 

 be found; and that all renal nerves belong to the sympathetic system. 

 The work was done by a modification of the rapid process of Gogli 

 which has not been made public. 



Nervous Ending's in the Mucous Layer of the Ileum. 



Dr. Henry J. Berkley'^ has applied the rapid Golgi method to 

 the ileum with good result within the musoca, while the plexi of 

 Auerbach and Meissner were not well differentiated. From the 

 ganglionic masses of Meissner's plexus numerous non-medulated 

 nerve fibres run in groups to the mucous layer. Many of the bundles 

 encircle the arterioles and branch upon them. The other branches 

 pass more directly to the mucosa where they branch and with the 

 others form a subplexus in the muscularis mucosae. Some of the 

 branches supply curious globular masses which are regarded as homo 

 logons with the motor end plates. Four or more fibres enter each
