METEOROLOGY. 



Rainfall at Watford and Kernel Hempstead. — The following 

 reports of the rainfall at "Watford House, Cassiobmy, and Nash 

 Mills, Hemel Hempstead, for the first quarter of the present year, 

 have been received : — 



From the 1873 Report of the Rainfall Committee of the British 

 Association we are enabled to compute the monthly fall of rain at 

 Nash Mills in the decade 1860-1869, the mean annual fall for this 

 period, and the monthly per-centage of the annual fall, being given 

 ia this report. It will be found to be as follows : — January, 2-88 ; 

 February, r58 ; March, 2-03; giving a total for the quarter of 

 6*49 inches. The rainfall (at Nash Mills) in the first three months 

 of this year was, therefore, rather more than an inch and a half 

 less than the average in the ten years referred to, the difference 

 being due to the small amount of rain that fell ia March. — Ed, 



GEOLOGY. 



Mineral Spring at Watford. — In the ' National Gazetteer of 

 Great Britain and Ireland,' under the head of "Watford, in vol. xi., 

 I read, " In 1689 a mineral spring was discovered here, the water 

 of which becomes as black as ink when mixed with nut-galls." I 

 should be glad if you would inquire of the members of the "Watford 

 Natural History Society if such a spring now exists, and where, 

 and its properties, and the analysis of the water. If the spring 

 no longer exists, what is the history of it ? — A. T. Brett, M.I). 



Botany of Hertfordshire. — During a short excursion in East 

 Herts, in company with Mr. Britten, of the British Museum, I 

 have found the true Myosotis sylvatica in profusion in several 

 localities. This is as good as new to our Hst, as a former record 

 could not be relied on. Poterium muricatu7n, another novelty, 

 Alopecurus fidvus, and other good things, were met with. I have 

 also been able to expunge a good many species from my list of 

 extincts, nearly all of which I have seen growing myself. Lepi- 

 dium Draha and Silene conica have both occurred as casuals, but 

 the former will, as elsewhere, in all probability become established.
