Delamain took a different view, arguing that instruments might very well
be placed in the hands of pupils from the start. At the time of this
controversy Delamain supported himself by teaching mathematics in London
and he advertised his ability to give instruction in mathematics,
including the use of instruments. Delamain brought the charge against
Oughtred of unjustly calling “many of the [British] Nobility and Gentry
doers of trickes and juglers.” To this Oughtred replies:
As I did to Delamain and to some others, so I did to William Forster: I
freely gave him my helpe and instruction in these faculties: only this

not William Forster for some time so much as speake of any Instrument,
except only the Globe it selfe; and to explicate, and worke the
questions of the Sphaere, by the way of the Analemma: which also
himselfe did describe for the present occasion. And this my restraint
from such pleasing avocations, and holding him to the strictnesse of
percept, brought forth this fruit, that in short time, even by his owne
skill, he could not onely use any Instrument he should see, but also
was able to delineate the like, and devise others.[143]

where Delamain refers to Oughtred’s charge that the scholars of “vulgar”
teachers are “doers of tricks, as it were iuglers.” Delamain says:
