40 THE ANIMAL PARASITES OF MAN 



these bodies is, to say the least, doubtful, 1 although it cannot be 

 denied that they possess a certain similarity to the marine Amoeba 

 fluida, Griiber or Greeff, and to a few other species. 



9. Leydenia gemmipara, Schaud.- 



In the fluid removed by puncture from two patients suffering 

 from ascites in the first medical clinic in Berlin, cellular bodies 

 with spontaneous movement were found which Leyden and 

 Schaudinn regard as distinct organisms. They remained alive 

 without the use of the heated object table for four or five 

 hours, the external temperature being 24 to 25 C. In a 

 quiescent condition they were of a spherical or irregular poly- 

 gonal form ; their surface was rarely smooth, being beset with

protuberances and excrescences. The substance of the body was 

 solid and permeated with light refracting nuclei with a yellowish 

 shimmer. The hyaline ectosarc was rarely seen distinctly. All 

 sizes from 0-003 to 0-036 mm. in diameter were observed. The 

 movements were rather sluggish, the ectosarc in the meantime 

 appearing in the form of one or several large lamellae in which 

 also strings of the granular endosarc appeared, and frequently 

 protruded over the border of the hyaline pseudopod. The
