Mounted on an album page this image shows Lt. Col. William Geroge Hamley of the Royal Engineers.

2nd Lieutenant - 3 August, 1833
1st Lieutenant - 25 September, 1836
Captain - 1 May, 1845
Lieut. Col. - 10 June, 1856

Harts' Amry List for 1860 does not show Hamley servingwith the rank of Major nor does it show him having served
on active service prior to 1860.

I believe this is Lt. Col W. G. Hamley who attended to gala opening of the Suez Canal and wrote a series of four
articles on the canal under the pseudonym "Scamper" that were published in
Blackwood's Edinburgh Magazine
under the title
A New Sea in an Old Land in 1871.
