[22]"gay"

should be

"gay."

[23]"gav"

should be

"guv."

[24]"(47)"

should be

"(47a)."

[25]"got" should be

"gaT."

[26]There

should

be

a

minus

sign

in

front of the first

term

on

the left-hand side.

[27]See

Hilbert 1915.

"p.

3"

should

be

"p.

395."

[28]The approach

taken

in

this section

was

first

developed

in

Einstein 1916b

(Doc. 27).

[29]"xp"

in the third

term

should be

"xo."

[30]"qvp"

should be

"gvß."

[31]"goT"

should be

"gpT."

[32]See

also Einstein 1915h

(Doc. 24)

for

an

earlier discussion of the

first

approximation.

[33]"p

a"

should be

"p

#

G."

[34]See

Freundlich 1915b.

See

also Hentschel

1994

for

a

historical discussion of

Freund-

lich's efforts

to prove

the existence of

gravitational

redshift.

[35]"Huggensche"

should be

"Huygenssche."

[36]This result

was

already

announced

in

Einstein

1915h

(Doc.

24),

p.

834.

The

calculation

proceeds along

the

same

lines

as

Einstein's

first

calculation of

gravitational light

deflection

in

Einstein 1911h

(Vol. 3,

Doc.

23), §4 (which gave

half the value obtained

here).
