acter and intensity of the former simulating nephritic colic. 
He looked very pale. Radiograms taken in the lumbosacral re- 
gion showed the characteristic evidences of beginning Arthritis 
deformans. Radiogram of the teeth showed the evidence of 
pyorrhea in the only remaining molar in the lower mandible, 
right side, and abscess in the second upper bicuspid, left. Un- 
der appropiate treatment of the affected teeth, and hygienic 
care of the mouth, he improved markedly, and the painful 
symptoms disappeared. Recovery was slow, and there was left 
some rigidity in the knees on account of the definite lesions 
observed in the articulations. 
Case 2.—F. L., adult, Filipino, male, married, complaining 
for many months of polyarticular rheumatism with acute ex- 
acerbations which prevented him from attending to his ordinary 
work. The medical and the dietetic treatments as well as the 
hydrotherapy given hiff afforded very little relief. Apparently 
his teeth were in excellent condition, but a radiogram showed 
the presence of an abscess in the remaining molar in the in- 
ferior maxilla, right side. Treatment of the dental abscess 
without any other medicine caused the gradual disappearance 
of his symptoms, and in four months he was completely cured. 
Case 3.—C. de C., female, Filipino, married; she gave a his- 
tory of some rheumatic pain; for two months she had been 
complaining of intense pain in the lumbosacral region, radiating 
to the left thigh. She was bedridden, and could neither sit 
nor walk. All previous treatment usually given in such cases 
was a failure, and the intense pain could be abated only by 
morphine injection. Radiograms of both kidneys and ureters 
were negative for stone; the vertebral column and the whole 
pelvis were entirely normal. Radiogram of both maxille showed 
the presence of abscess in both first molars in the superior man- 
dible. Both molars were extracted under anesthesia, and cul- 
tures of Micrococcus viridans and Staphylococcus albus were 
obtained. Autovaccine was prepared and all other treatment 
previously given was suspended. The first injection given was 
33,000,000; on the third day she was given another of 50,000,000. 
On the day following the first injection there were observed 
dizziness, nausea, and pain in the teeth, worse on mastication 
and on drinking cold water. On the sixth day after the first 
injection she was given another of 50,000,000, and thereafter 
100,000,000, at two-day intervals. After the third injection there 
was abatement of the symptoms observed after the second one 
and, to her surprise, she was able to sleep and to move her lower
