Rodinal of Old

I am perusing a yellowed old book,

Hiscox, Gardner E and T. O'Connor Sloane, FORTUNES In FORMULAS for Home, Farm, and Workshop, ( The Norman W. Henley Publishing Co, 1907 thru-1937.

There is a long chapter on Photography with many neat formulas, and techniques. This section must be from the earliest editions, because it contains a section on Platinum printing. It seems to refer only to glass plates, also.

However, what I found of interest is a very short notation:
Quote on: Rodinal Developer,--One part rodinal (sic) to 30 parts pure water. Use repeatedly, adding fresh as required. Quote off. p. 524.

Thoughts anyone? Anyone ever heard of replenishing working dilution Rodinal?.

I'm figuring 'one-shot' is a rather recent (mid-century) convention?

My favorite book of my youth. You have to remember that the film were plates or sheets. Development may also have been by inspection. So as it exhausted add more.

Following David's comment, we probably are more prone to throw anything away today than when this article was written. Also, our expectation and desire for control in exposure/development today might be greater than the earlier days of photography, when (prior to the Zone System, for example) success was achieved just having usable images on the film, and variation in the process might have been accepted as part of the game. I'm not old enough to know....

imagine how long a bottle would last if it could be replenished ?

Well Agfa's own books from the very early 1900's say Rodinal is single use, and it always has been along with it's clones from Kodak "Kodinol" and Ilford "Certinal" etc. But then Agfa also comment about storing it diluted..

It probably works OK replenished but it's safer to make fresh for negatives, but it was also recommended for prints by Agfa, and here relenishment might be more useful.

Thanks, Ian. That, to me, is a clearer than anything I have read about
Rodinal in a long time. I ASS u ME those measurements are Imperial Standard.

Also,I can see how the o.p. would apply to plates and prints being developed by inspection.

As it is, Rodinal is cheap enough that I cannot really see trying to save it.

American Imperial measures, the book was published by Agfa US / Berlin Aniline Company, of New York
