— [228], in place of equations at l. 16, put “R × a = R′ × (2 d × t)”,

whence d = R × a
2R′ × t;

where a = area of rivet,

d = distance,

t = plate thickness.

— [229], in art. 242, the strengths of “wrought iron,” have been taken for those of “boiler plate”; that is, 11,000 for 7,500, and 15,000 for 12,740, which is wrong.

— [231], l. 21, for “chopped,” read “dropped.”

— [234], l. 4, for “joint,” read “just.”

— [235], l. 14, for “0.016 feet,” read “0.047 feet.”

— [236], l. 9, for “care,” read “ease.”
