If my theory fails

Begin with This is very nearly the idea published by Mr Waterhouse, Mr Waterhouse theory, as remark by him having one

These notes allude to Waterhouse theory, but do not give, say dependent on cells surrounding other cells. Thus far I cannot doubt from many spec shown me. Hive Bee. Mud Polistes - one case of solitary social Wasp but Icaria case a great difficulty L B. has disproved theory. Make [illeg] about W. Kindness. Then give case of Hexagonal comb of sub-genus of Polistes - eggs deposited in hexagonal rows.

Mr Waterhouse was not aware of case of Melipona.

I think Wasps must first trace the circles at base in order to get the planes of intersection & then build up - if ever circular at bottom & then hexagonal this wd not do. In Bees, comb when bent & hexagons reduced or increased - it is difficult to see how. But 2 Bees at work cd form central plane.

I may avoid my 2d assumption by saying it stood for given distance from 1 or more adjoining circles or spheres.

I might give as reason for full discussion case of how falsely an instinct appears complicated beyond bounds.

Notes for my theory

The necessity of incessant remodelling from outer cells is shown in exterior edge, which will be added to of comb, in which outer cells have created walls, which will have to be remodelled uniting into hexagons.

Does any member of Vespidæ build spherical cells - or in agglomeration. Read Huber's work in French 15 francs.

In Hive Bees Hexagonal tubes of no definite length

P. Huber in Mem. Geneva p. 13 "il y a fond pyramidal partout ou trois fonds se rapprochement"…"le tube serait représenté par la partie convexe des outres"
