After writing this I was fearful I had got beyond my depth
in Greek remembering ον is neuter I turned to my old grammar
but not satisfying myself I called on Dr [Thomas] Miner. he
furnished my with the following remarks

* "It is well believed that Greek nouns in ον and Latin in
um when derived from the Greek ον are always neuter
but there are a few Latin nouns especially in
Botanical terms which end in um borrowed from
the Greek ΩΝ that are of the masculine or whatever
gender the original Greek may be. Consequently
the general Latin rule that nouns in um are
neuter admits a few exceptions but these
exceptions perhaps always have respect towards
in which the Greek ΩΝ is changed into um"
Dr Miner.
