patients suffering from a pure Shiga or Flexner type, agglutinating 
the specific sera. Vaillard’s anti-dysenteric serum was used with 
most gratifying results in several acute cases. Unfortunately we were 
only able to import a small supply. 
ABSCESS OF LIVER 
Amoebic dysentery furnishes a few cases annually. We have to 
record the extremely rare complication of liver abscess following a 
severe attack of yellow fever. Two cases occurred, and from one a 
bacillus of the para-colon type was isolated from the pus. Both 
patients had exhibited exceptionally severe icterus, which had 
persisted for some months after recovery from the original disease. 
The abscesses were noted six and ten weeks respectively after 
convalescence. No history of dysentery was obtainable, nor was it 
probable that these patients had suffered from the disease. 
DIARRHOEAS OF CHILDREN 
Infantile diarrhoeas are of frequent occurrence in Manaos, and are 
the cause of a high mortality. The suburban child is probably already 
infected with malaria and ankylostomes, and therefore falls an easy 
victim to any gastro-intestinal affection. The diet of the average 
child of the respectable poor is ill-adapted to sustain and nourish its 
bodily requirements. 
We have examined the faeces of many children suffering from 
severe diarrhoeas, and have found, in a child of four years of age, 
enormous numbers of Tyroglyphines, which were voided with every 
evacuation. Specimens were sent to England for identification, but 
the tubes were mislaid, and when discovered were so penetrated by 
mould that identification was impossible. We have had two cases in 
adults suffering from acute enteritis, accompanied by the discharge of 
much blood ; in the blood clots hundreds of small acarines were 
moving about. Both patients remembered that they had eaten a large 
amount of fruit, over-ripe bananas, etc., and one of them had subsisted 
on mouldy farinha. All the patients were rid of these pests by 
irrigations of boric acid and eucalyptus. We have seen acarines in 
the faeces of people who had partaken of much cheese. These were 
probably Tyroglyphus siro L., and in these latter cases no
