STUDIES ON INFANT MORTALITY.

dysentery, acute or simple meningitis and probably also as infantile beriberi, con- 

 vulsions of children, and some other forms of disease. 



2. Cholera in children is often atypical, and in these cases diagnosis is ex- 

 tremely difficult, if not impossible, without bacteriological examination of the 

 intestinal contents. 



3. Cerebral manifestations in children suffering from cholera are very common 

 and their severity is in inverse proportion to the age of the child. 



4. Acute meningitis is a very rare disease in Manila, in spite of statistics. 



5. The percentage of children attacked by cholera is higher than is shown by 

 statistics. 



In our work we are able to confirm the conclusions expressed above in 

 regard to meningitis and cholera, and to present additional data bearing 

 upon infantile beriberi, convulsions of children, enteritis, bronchitis and 

 broncho-pneumonia. The clinical history as gleaned from the family 

 or attending physician is given in the tables. These histories are meager 

 and are not always reliable, owing to the fact that the case is often seen 

 late in the disease and to the difficulty of getting correct data from the 

 family. However, it is unlikely that all the histories are unreliable, 

 particularly as the unanimity is so marked. 



In all cases of meningitis, beriberi, convulsions and bronchitis the 

 necropsy findings are given. In the cases of enteritis and dysentery, 

 necropsies were not performed in every instance, and confirmation of the 

 diagnosis of Asiatic cholera was secured by bacteriologic examination of 

 the intestinal contents at the Bureau of Science.
