What is "not so neither"

Neither \Nei"ther\, conj. Not either; generally used to introduce the first of two or more co["o]rdinate clauses of which those that follow begin with nor.

Fight neither with small nor great, save only with the king.
--1 Kings xxii. 31.

Hadst thou been firm and fixed in thy dissent, Neither had I transgressed, nor thou with me.
--Milton.

When she put it on, she made me vow That I should neither sell, nor give, nor lose it.
--Shak.

Note: Neither was formerly often used where we now use nor. ``For neither circumcision, neither uncircumcision is anything at all.''
--Tyndale. ``Ye shall not eat of it, neither shall ye touch it.''
--Gen. iii. 3. Neither is sometimes used colloquially at the end of a clause to enforce a foregoing negative (nor, not, no). ``He is very tall, but not too tall neither.''
--Addison. '' `I care not for his thrust' `No, nor I neither.'''
--Shak.

Not so neither, by no means. [Obs.]
--Shak.
