Appearances, such as those of Fig. 80, are not uncommon in this infection 

 (Wagenmann, Vossius, Axenfeld) ; in other infective metastases of the retina they 

 have not been observed. The distribution of the Streptococci along the vessels 

 remains longer visible than in the case of the other organisms, as the chains keep

together longer. In many streptococcal metastases it is possible to find masses 

 of cocci inside the vessels for a longer time than is the case with Pneumococci, 

 the latter organism more rapidly passing through the walls of the vessels, and 

 disappearing in all directions.
