The distribution of deaths by ages in 1930 and recent preceding periods is shown in the following table:—

Period.	0 -	1 -	4 _	5-	10-	15-	20-	25-	35-	45-	55-	65+	All ages.

It will be seen from the following table that one of the chief causes of the low rate was the decrease in mortality from respiratory diseases.

The heart condition in 810 of these children was found to be normal, and in 272 there was evidence that the heart was affected. It should be noted that "no swimming" is not classed as a restriction since practically all these rheumatic children are forbidden to swim for a time after their return from hospital.

The Table would be of greater value if distinction was made between complete and incomplete tonsillectomies but it was found that insufficient material existed for making this sub-division. One's impressions certainly are, however, that whilst a completely tonsillectomised rheumatic child is better off than his non-tonsillectomised brother, he will be better off with his tonsils intact (even though they be unhealthy) than with tags remaining after an incomplete operation.

120 tables in this report

The distribution of deaths by ages in 1930 and recent preceding periods is shown in the following table:—

It will be seen from the following table that one of the chief causes of the low rate was the decrease in mortality from respiratory diseases.

The following table shows the notified cases which occurred during the year, and it will be observed that the disease was most prevalent in the Northern and Eastern districts.

Smallpox Deaths, 1930.

The deaths in successive four-weekly periods in the epidemic of 1929-1930 compare with the figures for the two preceding epidemics as follows:—

Vital statistics for the several metropolitan boroughs and the County of London in the year 1930. (Rates per 1,000 of civil population.)

Number of cases of infectious disease notified in the County of London during the 53 weeks ended 3rd January, 1931.

Notifications received in each registration year since 1920, excluding duplicate notifications and military cases:—

The following is an analysis of the notifications in London during 1930 (52 weeks ended 27th Dec.).

In addition to the primary cases notified on forms A and B shown in the above tables, a number of cases came to the knowledge of medical officers of health, otherwise than by notification. These figures include cases not notified before death:—

The source of information as to the unnotified cases shown in the above table was as follows:—

Seamen's Lodging Houses Governed by By-laws.

Some attempt to classify the nationality of the seamen accommodated in the various licensed houses has been made in the following table, which must, necessarily, be regarded as approximate only:—

TABLE I. Showing the number of homeless persons found in the streets, and inmates of common lodging houses and casual wards on the night of the census.

TABLE II. Showing the total number of persons who might be regarded as homeless because they were unable to pay for a bed.

TABLE III. Showing the number of homeless persons distributed according to locality on 13th February, 1910, and 14th February, 1930.

COUNTY OF LONDON. Statistics of the administrative work carried out during the year 1930.

Sanitary Inspectors, 1930.

The results of the routine inspections of the herds are shewn ir the following table:—

The distribution of new cases of venereal disease between the sexes is shown in the following table, the figures for the preceding years being given for comparison:—

Comparative figures for the fourteen years during which the scheme has been in force are shown in the following table:—

Comparative figures for the fourteen years are shown in the following table:—

The following table indicates the number of applications from adults for residential treatment during each of the last five years:—

During the year, 1,195 patients were discharged from "observation beds"and their classification was as follows (the corresponding figures for 1929 are also given):—

The condition of the children under 16 years of age (on admission) who were discharged from residential institutions in 1930 is indicated in the following table. The figures in brackets are those for 1929:—

The following table shows the result of the enquiry and also (in brackets) the corresponding figures ascertained from last year's enquiry into the 1923 cases:—

The mortality records are as follows. (The figures in brackets refer to last year's enquiry into the 1923 cases):—

The mortality rates of the non-pulmonary cases classified according to the location of the disease are as follows:—

Thames River Samples (18 examined).

The incidence of cases classified under clinical type as well as grade of defect is shown in the following table:—

The previous educational history in these cases was as follows:—

The educational attainments of the feeble-minded were:—

The following table gives in greater detail the causes of blindness in the total of 355 (173 males and 182 females).

The total number of samples examined in the central laboratory during E the year amounted to 8,014, and the following table shows their number anddescription:—

Samples of feeding stuffs

Samples of fertilisers

In each year. In the following table, in which appears the percentage of under-nourished children found in each year in each age and sex group, it will be seen that they all share equally in their contributions to the general improvement of the whole.

The relationship between the type of school and the incidence of physical signs associated with rickets is shown by the Committee in the following table, the schools being classified in a descending scale according to social type as B-j-, B, B— and C.

Rheumatism Scheme, 1930.

The number of children nominated for hospital treatment during the year was 639. The agencies nominating these children were:—

The ages of the children admitted to hospital were as follows:—

The condition of the 324 children admitted to hospital is set out in the following table:—

Registered Rheumatic Children. these registered rheumatic children throughout the metropolitan boroughs is shown in the table given below:—

The incidence of the varieties of valvular disease was reported:—

In Table I are shown the number of cases attending the three centres during the year and in Table II the total number of inspections actually carried out. Table I.

The discharges are set out in Table III. Comment on the small number of cases discharged is made elsewhere. Table III.

Table 4 shows the arrangements which have been made for institutional treatment for the children attending.

Table 5 shows the arrangements which have been made for the children with regard to school attendance.

Table 6 shows a classification of the cases seen.

Table 8 shows a classification of the various cases considered to be suffering from organic carditis. In addition there were 11 cases of congenital morbus cordis ; one of these had chorea, 10 were non-rheumatic.

Table 9 shows the occurrence of murmurs considered to be "functional."

Table 10 supports the established view that sinus arrhythmia is essentially a physiological event. The opinion further is submitted that, when this irregularity appears in a heart which is diseased, it is some evidence that it is recovering.
