Matters to be referred to in my new book
A.B.J. [American Bee Journal] Vol. 2, p.74 History of the discovery of impregnation of Queen Bee
Oxford, June 12th, 1885 Bricks for hollow walls, etc. 
I have today devised a plan for
using my son in law's (H. C. Cowes) [illegible] brick for building
[illegible] walls which seems to me to have great advantages over any
[illegible] 1st Both the outer and inner walls may be all
[illegible] up with his building brick A - entirely [illegible] with the
[illegible] which is a source of [illegible] to the walls. 
The plans our [illegible] this brick takes the place of a [illegible] brick
and is laid [illegible] side corners at such intervals
as may be needed 2 [illegible] equal strength. [illegible] as a
binder there [illegible] metallic [illegible] right angles end end and
each downward and goes into a bottom or slot [illegible] brick 
this metallic binder held firmly [illegible] 
role. It may be made [illegible] if more width this on the 
[illegible] is needed, and maybe [illegible] boxes struck 
up [illegible] which serves as borders [illegible] laying on some
[illegible] if these boxes were [illegible] the upper and [illegible] on the lower 
[illegible] if binders it might work better. In this 
way [illegible] will [illegible] be built so [illegible]
[illegible] to fill and leaving space to be filled with [illegible] 
murder between the inside [illegible] this plan [illegible] making
[illegible] sizes of walls by bricks then is [illegible] that the [illegible]
A brick should be square 1 1/2 X 1 1/2 [illegible]
[illegible] of brick a may be 1 1/2 x 1 1/2 [illegible] is 3 inches wide
and A may [illegible] 9 1/2 x 4 x 3 maybe 9 1/4 x 4 x 2 1/2 first size
[illegible] 16 cubic inches [illegible] 
percent in [illegible] lighter [illegible]
