When Home Sapions gets into the water his sanity seems often to become
so diluted that he is unable to take care of himself, At a great eastern
summer resort, a fer years ago, the-life guards were throrm into a panic by
150 early morning bathers ettempting to ~ade the Atlantic. Thev came out of
their hotels to the beach and marched into the ocean vith the confidence of four-
year-olds paddling in the baby's bath. Once they vere beyond their depth, the
tide took them in charge, and all the life rescuing facilities of that world
reno™ned resort vere taxed to the utmost to save its reputation and its patrons
“ho regarded either depth nor wave,

In passing it is interesting to note not only has man developed a
strange mental attitude ~hen around reter, but he has also lost his fins and
only as a "thror-back" has webbed toes and fingers. Webbing of the toes and
fingers is a dominant characteristic - a hint thet such a structure once had its
special function and that he may be more closely related to Donald, the Duck,
than the comic strip may iridicate. Another fact hich suggests that man's
primordial existence vas aquatic is the concentration of minerals in his blood
stream. The ionic composition of the blood of a man and a jelly fish or of a
max and a lobster are so similer as to suggest their ancesters floated lazily
together in the Archaean Ocean. It also indicates the conditions under “hich
ceil life is possible are very restricted indeed and have not changed substantial-
ly since life first began.

It has been many million millennie since our equatic ancestors slid
out of the nrimeval ooze, found they could live in the air, and did not return
at night. Through many era since, evolution has wrought many changes, among
them the development of eyes, ears, end sinuses which are rather poorly adepted
to swimming - a maladjustment which is the price of breaking home ties.

Without a nictitating membrane to protect the cornea end conjunctive
egainst injury, trouble ~ith the eyes frequently results from svimming. The
temperature of the water differs markedly from that of the body, end is con-
ducive to discomfort of the eyes. Its mineral content may also injure the eves.
Osmosis and the washing out of immune bodies may likevise have an effect. Many
of us know how much easier slightly salt vater is on the eves than soft fresh
water, When residual chlorine rises above 0.5 p.p.m. trouble with hyper-sensitive
eyes is not far off. Many individuals may vithstand severel times this amount
but those less resistant 7ill have various grades of conjunctivitis or mild
inflammation of the eves. With the use of ammonia the chlorine content of the
pool may be raised as high as 1,00 p.p.m. without cevsing many complaints.

It should be remembered that eves are often as different as are
individuels. Susceotibility, hypersensitiveness, end allergy rarely behave
according to fixed stendards. Lack of complaint is not alvays proof of the
harmlessness of a chemical nor is failure to report trouble an indication
that no symptoms of irritation are evident. Inflammation of the eves may be
@ sign of pollution of the vater. Crgenisms which ordinarily attack the eves
may, under especially favorable circumstances, pass from one individual to
another. The use of the same tovel or soap around bathing places is vrobably
often responsible for the spread of eye infections which are frequently
attributed to the lack of sanitation of the pool, or to too much chlorine.

Infection of the ear, nose, and throat mey come either from the nasal
passages of the individual or from a grossly polluted pool. By rare chance,
highly virulent bacteria may be conveyed by water from one person to another,
