The interruption in the mails has prevented mo from
SEEING until yesterday article in your paper the
signature Of 3d. attacking Lieut. Maurys defence Of bis
report upon the recent eegaphc survey He has occu.
pied most OF his communication in the attempt provo
that this report published without the authority or
appreciation of the Secretary OF the Navy.
But this has nothing do with the correctness of tho
report of Lieut. Maury, and is matter entirely between
the Secretary Of the Navy and himself in which the public
has concern, and feel interest shall not notice
what he says upon this subject SHALL theref re- confne
remarks to the objections which aB makes to the JUS
ce OF Lieut. Maurys report upon the teegraphc survey

inventor of the apparatus by which and without which
Lieut. Bergman could have obtained he abundant
specimens from the bottom of the which aB places
in the front rank of all the results of his survey in tho
Arctic Yet it is fact notorious to all who have any
knowledge upon the subject that Brookes lead was the
first and may be added the only continuance by which
specimens from the bottom Of the deep have ever been
obtained or can even be obtained But OBJ il a.
dumb as an oyster in regard to the Of the inventor Of
this valuable apparatus to which Lieut. Bergman was In
debted for results which "Bp himself places st in the
list of Lieutenant Berymans achievements in the survey
Of the telegraphic plateau and it is little remarkable
that in all the publications made by the officers of this ex
petition, the name of Brooke completely ignored
