Thanks a lot for making the paper by Smith (1935) accessible to me, which
was in turn requested by a good number of ANNELIDA users.
Once I have been able to pin down the concept of density dependence (in fact
sensu density-dependent mortality factors), I am now tracking the original
definition of the concept of regulation in the context of population
dynamics where it refers to population size self-adjustment, where density
dependence might [I am not sure yet] represent the otherwise called return
tendency, i.e. mortality rates increasing and birth rates decreasing as
population size increases. This is much harder a task since regulation is
quite a rather general, easy-to-use term.
The theory of population regulation seems to be attributed to Alexander John
Nicholson (see Turchin 2003, p. 5, and others), and in fact the origin of
the (still debated, see White 2008) regulation versus limitation controversy
is most commonly associated with the exchange of ideas between Nicholson and
Herbert Andrewartha at the Cold Spring Harbour Symposium in the 1950s. I
have been able to track two of Nicholsons seminal publications (Nicholson
1933, 1954), but funnily enough although Nicholson does use the term, no
definition is provided.
I have a double request if you can possibly help.
1.- Whether you can point me to a proper reference where I can find or
pursue the original definition of regulation.
2.- Whether you have access to the following three old references:

Spring Harbor Symposium of Quantitative Biology 22, 219-232.

I am currently working on a manuscript on density-dependence (DD) detection
across taxa. I have been unable to find at my university and from colleagues
nearby the old paper by Smith (1935) in which the term DD is used for the
first time to define the population regulation negative feedbacks, i.e.
Smith 1935. The role of biotic factors in the determination of population
densities. Journal of Economic Entomology 28, 873-898.
If you had it available, I would very much appreciate a pdf copy of this
old reference. Many thanks for your time on this request,
