Chapin 1912.

Talking about droplets and airborne. To him "airborne" meant long-range as in many kilometers. Droplet could be through the air more than 1 or 2 m. Plus, he said study it more! We have failed to do that.

Quick thread.

12 foot droplets? I guess they shrunk over the years.

Also, ring worm may be through air.
Page 281. Plague. Droplets means through air over distance, but not long-range.

Note that MASKS WORKED.
page 295. Droplets detected, Flugge first found them during SPEAKING, LOUD TALKING, COUGHING and SNEEZING. Tiny droplets. Yup.

Note found 2 meters BEHIND the person

So clearly, our "droplet" has morphed from Chapin's droplet. That's weird.
p 296. How much do they travel? Well even Chapin said droplets fill a room. Five to six hours. Interesting.

(He then goes on to wonder if they are infective, same arguments as today ... sigh ... and he didn't have 100 years of studies to help him.)
p 297. ... on the next page Chapin talks about an experiment that found no strep in saliva in air (aerosol, let's call it), so Chapin expresses doubt this is more than minor.
Here is the minor comment:
p 298 - thinks float.

Flu floats. (He calls it a bacteria because viruses had just in 1898 and forward begun to be discovered and characterized).
p 298. Far more value and interest derive from the AIR NEAR THE SICK.
p 302. That Flugge developed the idea that TB spread by droplets, rather than dust (TB bacteria spat out, that would dry out and float around on dust).

But this is interesting, because Flugge knew that this wasn't limited to 2m, but WOULD FILL A ROOM.
p 305. There is then discussion of experiments where guinea pigs were not infected at distance of 1m from a coughing TB patient. (However, my recollection is Flugge found otherwise.)

So, two theories, dust vs droplet. But recall droplet means "stuff spat out and that floats"
Le Fin.

This was something I looked through while looking for something else (Chapin's droplets "makes sense" to him, quote)

And now you see why I say that every time I open a book I find more contradictory nonsense.

Lyrics:

When we lift the covers from our feelings
We expose our insecure spots
Trust is just as rare as devotion —
Forgive us our cynical thoughts
If we need too much attention —
Not content with being cool
We must throw ourselves wide open
And start acting like a fool

If we need too much approval
Then the cuts can seem too cruel

Right to the heart of the matter
Right to the beautiful part
Illusions are painfully shattered
Right where discovery starts
In the secret wells of emotion
Buried deep in our hearts

It’s true that love can change us
But never quite enough
Sometimes we are too tender
Sometimes we’re too tough
If we get too much attention
It gets hard to overrule
So often fragile power turns
To scorn and ridicule
Sometimes our big splashes
Are just ripples in the pool
