of amoebiasis with 10 deaths, and 253 cases of bacillary dysentery with 14 deaths.
85. As usual the non-Chinese population showed a relative- ly greater susceptibility than the Chinese population.
86. Poliomyelitis.
This disease has become more serious in this Colony as elsewhere throughout the world in recent years. There were in 1951, 28 cases with 3 deaths as against 16 cases with 3 deaths in 1950. The non-Chinese population appeared to be dis- proportionally susceptible.
87. Diphtheria.
The incidence of this disease showed a 10% increase but the fatality rate decreased markedly.
88. There have been 574 cases with 121 deaths as against 524 cases with 195 deaths in 1950.
89. The disease mainly affects children in the second and third years of life (60%) but the fatality rate is very high among infants below 1 year of age.
90. An absence of immunization of infants and youngsters is the cause of the high incidence, and a preference for Chinese herbalist treatment rather than for early scientific treatment is responsible for the deaths of the infected.
91. Cerebrospinal Meningitis.
There have been 26 cases with 13 deaths, as against 49
cases with 26 deaths in 1950.
92. The disease affects Chinese children almost exclusively and the incidence has fallen markedly during the last few years.

97. There have been 747 cases with 20 deaths against 306 cases with 16 deaths in 1950,
98. Puerperal fever.
