 gives the following conclusions of his studies by means of the 

 Weigert method upon many mammals, including artiodactyla, 

 peris sodacty la, rodent ia, insectivora, carnivora, and primates. 

 Fibers found in relation to the pineal body are : 

 1. Prepineal fibers: 



a) Transverse commissural 



6) Oblique commissural

 according to Dimitrova, 1901. 



2. Fibrae seu fasciculus prepinealis. 



3. Pineal fibers: 



a) Superior transverse commissural fibers 

 6) Superior oblique commissural fibers 



c) Posterior transverse commissural fibers 



d) Diagonal commissural fibers 



e) Superior and posterior fibrae propriae 



Anglade and Ducos ('08-09) 5 found neuroglia constantly 

 present in the human pineal body but also alveoli-formed cells
