" This water is free from organic impurity, but is hard." 



"The supply is intermittent, and amounts to 36 gallons per head 

 per diem." 



"The New Buslu'V portion of the town is supplied by the Cohie 

 Valley Waterworks with water also from deep wells in the 

 Clialk, but softened before distribution." 



(p. 3) Speaking of Bushey, we are told that "There arc a large 

 number of cesspools in use in the parish," and that "there are 

 still thirty-two houses in the part of the parish next Watford not 

 supplied by the waterworks ; most of these houses have their own 

 Avells, some of which are not above suspicion of being liable to 

 contamination." 



(p. 5) " At Bushey the general dampness of the soil and the 

 damp, dirty, ill-ventilated dwellings probably predispose persons 

 resident in them to attacks of diphtheria." 



(p. 6) "There were no circumstances that cast any suspicion 

 on the water supply as a source of infection." 



At the end of his paper " On the Origin of the High-level 

 Gravel with Triassic Debiis adjoining the Valley of the Upper 

 Thames," Mr. H. J. 0. White refers to the masses of gravel and 

 sand along the Tertiary escarpment by Rickmansworth and Hatfield,

 lying at a considerable distance to the north-east of, the Goring 

 Gorge." * 



Dr. A. Irving has given an account of an excursion to Bishop's 

 Stortford, noticing the Chalk, the older Tertiary beds, and more 

 especially the Drift, besides the Hertfordshire Pudding-stone, f 



In a general paper, " The Chalky Boulder-clay and the Glacial 

 Phenomena of the Western - Midland Counties of England," 

 Mr. H. B. Woodward occasionally refers to Hertfordshire.! 



Mr. F. Chapman published a paper on " Ostracoda from the 

 Chara-maii of Hitchin." That fresh-water bed, which is remark- 

 ably rich in these microscopic forms, is a calcareous loam and 

 comes between a gravel below and a brickearth above. Fifteen 

 forms are noticed, several being figured. § 



In an Address to the Sanitary Institute, I alluded to the 

 outbi'eak of the Hertfordshire Bourne, contrasting its lateness, as 

 compared with the outflow in the Kenley Valley, Surrey ; but
