If we now consider the eleven spirals 8 — 18, we obtain:

Regarding these determinations we desire to add, that the former group gives 

 a result differing only immaterially from the first value found for all the spirals. 

 The introducing of K seems not to be pretty well accounted for in this case. For 

 the group 8 — 18 we obtain with the other determinations not so well agreeing Apex
