SUMMARY AND CONCLUSIONS 
The observations of Osborne and Mendel on rats indicate a 
possible association of dietetic deficiency with the formation of 
phosphatic urinary calculi. The Filipino diet is essentially of 
an insufficient and limited character, particularly in its vitamine 
content. Beriberi is still frequently encountered in these Islands, 
and Saleeby and others have indicated the frequency of the dis- 
ease in a latent form which, with further limitation in diet, 
may become active and widespread. My personal experience in 
the Philippine General Hospital confirms this view. The results 
of the present investigation show that a relation apparently 
exists between the general dietetic inadequacy and deficiency 
among Filipinos and the incidence of phosphatic calculi, in con- 
trast with the reported predominance of uric acid and urate 
calculi in Europe and the United States, ' 
Of ten cases of cystolithiasis which I have particularly studied 
since this investigation was undertaken, nine not only gave a 
history of having had beriberi, but exhibited actual signs refer- 
able to the disease. Although the clinical data of all but two
