The figures show small incinerators in use in a mill and in a 

 gaol in Colombo, but it must be remembered that faeces require 

 a considerable amount of fuel and a considerable draught before

is estimated to pass 8 ounces of faecal matter per diem in a mixed 

 population of races, sexes, and ages, and 40 ounces of urine. The 

 usual size of a galvanized iron latrine-bucket is 14 inches high by 

 12 inches broad at the mouth and 9 inches at the base, and it has a 

 cubic capacity of 0-9 cubic foot, and is said to weigh 10 pounds 

 when full. Coir fibre is often mixed with the faecal matter in the 

 proportion of 2J pounds of coir to i pound of faecal matter or i gallon 

 of urine.
