CHAPTER XII.

SEASONS AND TIMES.

It is an old, old story that the destinies of man are _governed_ by

the sun, moon, and planets; but modern science rather scouted the

ideas of the astrologers and Chaldeans; to suicide is due the honour

of reintroducing the connection. Morselli says, with regard to the

sun, “It is in fact well known that the number of these violent

deaths varies according to the position of the earth and the sun. In

the season of the year in which the earth is in aphelion there is a

_maximum_, of suicide; when in perihelion the _minimum_ is attained.”

The result of a large collection of statistics shows, however, that the

maximum suicide rate occurs in summer 88 times out of 100, as opposed

to winter; in spring the maximum occurred 9 times in 100. As to the

minimum, it occurs in winter 88 times out of 100, and only 12 times in

autumn out of the same number of observations.

As to the months, in a general way, suicide increases from January to

July, and then decreases again, month by month, to the end of the

year. Reckoning by cities only, instead of by states, the results are a

little upset, but in 11 cases of large numbers, 9 maxima fell in May,

June, and July. The number of cases of mental disease has been observed

to vary in similar months, reaching their maximum in the heat of summer.

The following Table of “Death Rates of each Season” may be compared

with the foregoing remarks on the “Seasonal Suicide rate”:

────────┬─────────┬─────────┬─────────┬─────────┬───────

── │ Spring. │ Summer. │ Autumn. │ Winter. │ TOTAL.

────────┼─────────┼─────────┼─────────┼─────────┼───────

England │ 110 │ 96 │ 95 │ 99 │ 400

France │ 117 │ 88 │ 86 │ 109 │ 400

Holland │ 88 │ 91 │ 126 │ 95 │ 400

Austria │ 115 │ 82 │ 91 │ 112 │ 400

Italy │ 88 │ 105 │ 100 │ 107 │ 400

────────┴─────────┴─────────┴─────────┴─────────┴───────

From these figures it will be apparent that the greatest mortality in

England falls to spring, and next to winter; or exactly opposite to the

tendency of suicide. In Italy only do the maxima of general mortality

and suicide coincide in the hotter two quarters of the year.

It is not so much the actual hot weather which seems to increase the

number of suicides and the amount of lunacy, nor the actual cold

weather which seems to check the number, as it is that the _onset_ of

hot weather seriously affects the human system in such a way as to

upset the equilibrium of mind function, and to suffer mental motives to

derange the intellect.

In these considerations the spring is reckoned as consisting of March,

April, and May, and the other seasons accordingly.

I do not find that these seasonal peculiarities are very marked in the

suicide rates of this country taken alone, not in London at any rate;

for example, I subjoin the figures obtained in Central Middlesex for

two years.

Summer │ 23 │ 37 ││ Winter │ 22 │ 26

The Annual Reports of the Registrar General do not throw any light

on this question, nor, I may say, on several other somewhat fanciful

investigations into which foreign observers have led the way.

Morselli states, “it is most probable that the moon exercises more or

less influence on suicides as it does on madness and epilepsy, which

are generally aggravated at the time of the waning moon (full moon and

second quarter).”

“The influence of the moon would be more sharply felt by men than

by women, particularly at new moon.” This last, it seems, is the

conclusion drawn from the labours of the modern astrologers of Prussia.

But from the statistics given by himself for 1869, it appears that

255·8 and 258·8 per 1,000 occurred respectively in the moon’s first

quarter and last quarter, against 246·8 and 238·6 per 1,000 in the new

moon and full moon quarters; no very marked difference.

With regard to days, Brierre de Boismont finds in regard to Paris that

the number of suicides in the first ten days of a month exceeds the

number of the last twenty; and, stranger still, the two first days

of the month also give the largest numbers: this does not occur in

England, nor in London alone.

As to week days, among men the beginning of the week is most fatal;

Monday highest, then Tuesday, then Wednesday, and Saturday the fewest.

Among women also peculiarities come out, but they are different;

Saturday has still the fewest, the Thursday and Friday are very high,

Monday and Tuesday low, but Sunday has the highest number of all.

And now with regard to hours and times of the day, darkness seems to

be preferred to daylight. But according to a rather complete set of

tables, which I reproduce here, giving every hour, night and day, I

find that from 6 a.m. to 10 a.m., about noon, and from 2 to 3 p.m. have

very much the highest numbers. The rate diminishes almost regularly

from 3 p.m., through midnight to 3 a.m., when the lowest number is

reached.

Brierre de Boismont arranged this Table; it refers to 1,993 cases

observed in Paris.
