1. Page 8--the formula for "d" must use a cube root, which is how it
is shown here, but the '3' to indicate a cube root is not found in
the original document.
2. Page 8--typo in word 'sectien'--changed to 'section'.
3. Page 10--Value for working comp. strength of cast iron in the
table had a typo (25,v00). Since other values use round numbers,
it is assumed the value should be 25,000.
4. Page 10--Two other typos. Changed 'the the' to 'the', and in
table heading, original word was 'detrution', changed to correct
spelling of 'detrusion'.
5. Page 12--changed 'woooden' to 'wooden'.
6. Page 13--Example II--In the calculations, the intermediate value
in the book was printed as the square root of 67.2. The left part
is correct, but reduces to the square root of 268.8, and that is
~16.395. So I have corrected the intermediate value.
7. Page 13--Because the original page scan cut off the text on the
right edge, I have made assumptions on what text was missing.
Because the scans came from an outside source, I could not get
the missing information, which was the words at the end of Example
II, and words in the last paragraph of the page.
8. Page 14--Three typos found: 'dimensiens' for 'dimensions', 'betng'
for 'being', and 'ars' for 'are'.
9. Page 17--a value in a formula was printed as 6000, but in the
context of the other information, particularly the example
immediately following, the value was believed to be incorrect, and
was changed to 5000.
10. Page 23--The value of 388 sq. inches at the top of the page in the
book is incorrect; 3 x 8 x 12 = 288, so has been corrected.
11. Page 24--Rods section, numerical value appeared to be 15.000 in
the book, but from context, must be 15,000 instead.
12. Page 28--Typos: changed 'Trautwine's Edgineer's Pocket-Bood' to
Trautwine's Engineer's Pocket-Book'; corrected 'af' to 'as',
'bracas' to 'braces'.
13. Page 30--Apparent typo in the table at the bottom of page. Value
for Center Brace size for 200' span was shown as '8 x 1', believed
from context of table to be '8 x 10'.
14. Page 33--table of dimensions of a Pratt Truss, last column, row
starting with 150, the original says 8--1-1/8, this is believed to
be, and has been changed to, 3--1-1/8.
15. Page 37--The five formulas with square roots were incorrectly
printed in the book, multiplying the terms inside the square root
instead of adding them, which is obviously incorrect per the
Pythagorean theorem of right triangles.
16. Page 38: The fifth ratio in the group of five near the top of the
page must start with 20, not 10 as in the book
17. Page 38--The equation for W as printed on this page is not
consistent with that found on pages 18 to 24, so has been corrected
from 'bd^2' to 'bd^3'.
18. Page 39--arch brace truss table heading typo-changed 'FOE' to 'FOR'.
