266 REPORT — 1876. 



his own way givu the formula complete, with its numerical coefficients, as 

 follows * : — 



where Q=the discharge in cubic feet per second; 

 L=the length of the notch in feet; 

 ii=the number of end contractions ; 

 7i=the height from the crest to the still-water surface-level in feet. 



Mr. Francis also states that this formula is not applicable to cases in which 

 the height h from the crest to the still-water surface-level exceeds one third 

 of the lengtli, nor to very small depths. In the experiments from which it 

 was determined the depths varied from 7 inches to 19 inches ; and he remarks 

 that there seems no reason why it should not be applied with safety to any 

 depths between 6 inches and 24 inches. 



Report of the Anthropometric Committee, consisting of Dr. Beddoe, 

 Lord Abehoare, Dr. Farr, Mr. Francis Galton, Sir Henry 

 Rawlinson, Colonel Lane Fox, Sir Rawson Rawson, Mr. James 

 Heywood, Dr. Mouat, Px'ofessor Rolleston, Mr. Hallett, Mr. 

 Fellows, and Professor Leone Levi. 



The Anthropometric Committee have been engaged during the past year 

 in preparatory work. They have secured the cooperation of gentlemen hold- 

 ing positions under Government as inspectors of the army, of the navy, of 

 factories, and of pauper schools. They have prepared schedules and instruc- 

 tions, and have had them printed ; and they have purchased a small outfit of 

 instruments to send to places where measurements are to be made in large 

 numbers. 



Under these circumstances they are unable to make a report of anthropo- 

 metric results ; neither have they been called upon to expend more than a 

 small portion of the grant of £100 that was made to them in 1875, the 

 larger part of which will be required to pay for the reduction of observations. 

 Consequently they ask that the Anthropometric Committee may be reap- 

 pointed, with modifications, and that the grant may be carried forward to the 

 year 1876.
