during pregnancy or the nursing period and yet in which we see 

 the attacks of infantile beriberi in their offspring or nurslings 

 seem to contradict the findings of Ingier and Goldmann(28) in 

 their experiments. The first found the lesions of scurvy more 

 marked in the skeleton of the mother than in the offspring. 



Seasonal prevalence. — Table VIII shows that infantile beriberi 

 is more prevalent in September, October, and November, disap- 

 pearing gradually with the approach of the hot season (April, 

 May, and June) , according to Andrews. (4) Our records between 

 January, 1910, and March, 1916, show the following annual and 

 monthly incidence:

As we can see, the only months that are more or less exempted 

 are May, June, and July, which are the beginning of the rainy 

 season and the time when palay, or rice, is planted. 



The annual occurrence is not the same, and Albert (2) thinks 

 that this may perhaps be explained by the lack of vitamines in 

 certain foods that is observed in certain periods due to agri- 

 cultural and economic causes-. 



If the record of 1910 is not taken, but only those of the follow- 

 ing years, the monthly incidence is completely different, and we 

 have January, 2 ; February, 1 ; March, 2 ; April, ; May, 1 ; June, 

 1 ; July, 3 ; August, 4 ; September, 5 ; October, 10 ; November, 17 ; 

 and December, 9; which gives the highest mortality during the 

 wet, moist, and cold months. The infrequency of infantile 

 beriberi of these last years may be due to the fact that even the 

 laity is aware of its symptoms, and artificial feeding is given at 

 once.
