404 REPORT — 1891. 



city. 37 per cent, of the tidal capacity on a 30-foot tide would represent 

 a mean increase of depth over the entire estnary of 11 feet; and as the 

 increase was by no means over the whole estnary, the increase in the 

 channels and lower estuary was much more than this, and although by 

 this time the sand in the estuary had for the most part become quite 

 yellow, sand was still being carried down into the generator. 



In the meantime, as already stated, groins similar to those in Experi- 

 ment VI. in tank F, had been introduced into experiment VII. in tank E, 

 after 64,000 tides had been I'un with spring and neap tides. 60,000 more 

 tides, which would be equivalent to about 27,000 spring tides, were run, 

 the effect being that, notwithstanding the difference in the initial condi- 

 tions, the state of the lower estuary was closely approximating to the 

 state of VI. in F after 36,000 tides (Plan 2, Experiment VII., tank 

 E; VI., tank F). 



In the upper estuary in VII., tank E, the distribution of the sand is 

 precisely similar to that in VI., tank F, but there is rather more of it, 

 which is explained partly by the fact of the difference in the equivalent 

 tides run, 30,000 in E as against 60,000 in F, after the upper groins were 

 put in, and partly by the much greater amount of sand still left in the 

 lower estuary in tank E. Had it been possible to run 250,000 more 

 spring and neap tides in VII., tank E, there is every reason to suppose 

 the final condition would have been precisely similar to that obtained in 

 Experiment VI. in tank F. 



Report of the Comvnittee, consisting of Professor Flower (Chair- 

 man)^ Dr. Garson [Secretary), Dr. Beddoe, Greneral Pitt-Rivers, 

 Mr. Francis Galton, and Dr. E. B. Tylor, appointed for the 

 purpose of editing a new Edition of ' Anthropological Notes 

 and Queries.' 



The Committee has to report that during the past year material progress 

 has been made in the work of editing the new edition of ' Anthropological 

 Notes and Queries.' The whole of the work is now in the press, and so 

 far advanced that it has been possible to present an advanced copy to the 

 Association along with this report, 



The editors are of opinion that the value of the work would be 

 enhanced by the addition of some additional illustrations to the first 

 part — Anthropography. 



The Committee considers the plate illustrating the colour of eyes, hair, 

 and skin — also submitted to the Association — a decided advance upon any- 

 thing that has been hitherto done in that way, and has every confidence 

 that if a further sum is placed at the disposal of the editors for illustra- 

 tions it will be spent to the best advantage. 



The Committee request to be reappointed, and that a further sum of 

 20^. be placed at its disposal for illustrations. 



The Committee in conclusion reports that best thanks are due to the 

 Anthropological Institute of Great Britain and Ireland (under the 

 auspices of which body the work is being edited) for undertaking
