SPIROCH^TE PALLID A 519 



the spirochaete pallida is now very large, and a summary of the 

 results may be given. In the primary sore and in the related 

 lymphatic glands, the juice of which can be conveniently 

 obtained by means of a hypodermic syringe, the organism has 

 been found in a very large majority of cases. It has been also 

 obtained in the papular and roseolar eruptions, in condylomata 

 and mucous patches in fact, one may say generally, in all the 

 primary and secondary lesions. Schaudinn in his last series of 

 cases, numbering over seventy, found it in all, and on a few 

 occasions detected it in the blood during life in secondary syphilis.

It has also been obtained from the spleen during life. In the 

 congenital form of the disease the organism may be present in 

 large numbers (Plate II., Fig. 6), as was first shown by Buschke 

 and Fischer, and by Levaditi. In the pemphigoid bullae, in 

 the blood, in the internal organs, the liver, lungs, spleen, supra- 

 renals, and even in the heart its detection may be comparatively 

 easy, owing to the large numbers present (Fig. 159). It has 

 been generally supposed that tertiary syphilitic lesions are non- 

 infective, and the results of the earlier observations on the 

 spirochsete pallida were apparently in accordance with this 

 view, as they gave negative results. More prolonged search 

 has, however, shown that the organism may occur in tertiary
