THE TIDAL REGIME OF THE MERSEY. 321 
in the flow, and remained somewhat later during the ebb, in 1903 than in 
1893 and 1894. This is probably due to the increased facility afforded 
for the ingress of the flood tide by the deepening of the bar. 
That this advance in the time of ingress of the current did not show 
itself in the lower and deeper reaches of the river might be explained by 
the fact, that the quantity of water entering is small compared with the 
much larger quantity already there. But in the fluvial portions of the 
river, above referred to, the amount of water brought by the tidal current 
must be considerable, compared with the land water in those parts of the 
river. 
In any case the result of this comparison of tidal curves representing 
an interval of thirty years, and extending over the whole tidal portion of 
the Mersey, confirms what the Harmonic Analysis indicates for the tides 
of Liverpool itself. 
The Committee desire to be allowed to present the thanks of the 
Association to the Mersey Docks and Harbour Board, and to their 
officials the General Manager and the Marine Surveyor, for their 
courtesy in having placed so much information at the disposal of the 
Committee in order to assist them in carrying out the objects for which 
they were appointed. Likewise the Committee wish to record their 
best thanks to Mr. Edward Roberts for having, at considerable incon- 
venience to himself, afforded them the information above referred to as 
to the Harmonic Analysis of the Liverpool tides of 1902. 
In conclusion, the Committee desire to put on record its gratitude to 
Mr. Shoolbred for his care in preparing the preceding Report ; and, 
generally, for all the time and thought which he has devoted to the inves- 
tigation of the subject submitted to it by the British Association. 
Archeological and Ethnological Researches in Crete.—Report of the

APPENDIX: Excavations at Knossos, Crete, 1904. By Dr. ARTHUR J EVANS. 322 
Tur Committee report that of the grant assigned to them at the South- 
port meeting of the Association the sum allocated to archeological research 
at Knossos has been paid over, as usual, to the Cretan Exploration Fund, 
and expended in furthering the exvavations of Dr. Arthur J. Evans, 
whose report on the season of 1904 is appended. 
The sum, which was allocated to ethnological research, was put at the 
disposal of Mr. W. L. H. Duckworth for the investigation of the physical 
characters of the ancient and modern population of Crete on the same 
conditions as last year. Mr. Duckworth, however, was not able to arrange 
to revisit Crete, as he had proposed, in the season of 1904, but the Com- 
mittee have every hope that he may be able to resume his observations 
there at an early date. A further grant is asked in aid of this branch of 
the Committee’s work. 
The work at Knossos also continues to promise results of the highest 
scientific importance, and the Committee therefore ask to be reappointed, 
with a further grant.
