But as it may happen that the space will not give room for these measures,he diameter may be reduced and divided according to the plates. The essence of theseilans, omitting the step whose plan is segmental, we here subjoin. 2S08. Fig. 997. is a plan and section of a staircase with a solid newel, in which theAhole diameter is divided into twelve parts, and of these four are given to the neuol,tad the rsmainder divided equally between the steps. 0 O 9:W PRACTICE OK AIICIHTECTURE.
