The degree of Humidity was only 14 thousandths less than the average. 

 The weight of a cubic foot of air was 7 grains less than the average. 

 Wind — less N. and S., more of E. and W. 

 Rain — 6 days more than the averat,'e ; quantity, i inch more. 



Comparing the results with the average of Hereford from 1846 to 1849, it 

 resulted that the Barometer and mean Temperature were higher in 1858 ; there 

 have been 10 days more of Rain, but 13 mches less in quantity. S. and W. Winds 

 have prevailed over N. and E. in the ratio of 3 to 2 nearly. Rather less than 

 half of the days in the year were overcast ; one-fourth were fair, and the re- 

 maining fourth variable. 



February was last year the coldest month, and June the hottest, although 

 in general Janujiry gth is the coldest day, and July 30th the hottest. The heat 

 of August last exceeded the average by only one-tenth of a degree. January and 

 December were the dampest months, and J une the dryest ; durmg the last quarter 

 of the year there was more moisture m the air than in the other three quarters. 



Thanks were voted, amid applause, to Mr. Smith, and it was agreed that 

 his Report should be printed in the Transactions. 



METEOROLOGICAL REPORT FOR 1858. 

 By J. E. Smith. 



All the instruments of the Society are in good order and preservation. To 

 those already in our possession, the following have been added : — 



1. A Black-bulb Maximum Thermometer. 



2. Minimum Spirit Thermometer, for terrestrial radiation on the grass. 



3. Liud's Anemometer for ascertaining the force of the wind. 



4. Dr. Moffat's Ozone papers, and wooden box for suspending them. 



I have also had a River Gauge painted on the wall of the Infirmary lawn, to 

 show the rise of the Wye at periods of flood ; and a Weathercock fixed on the top 

 of the building. 



The Record of Observations has been kept with tolerable regularity through- 

 out the year, and the monthly summaries, with the deductions from them, 

 accompany this report. 



Several interesting Meteorological phenomena have occurred during the 

 past year. 



A Total Eclipse of the Sun happened on the 15 th of March, and in com- 

 pliance with a request from the Meteorological Society, which I lay before you, 

 I made observations every five minutes during the eclipse, and sent the results 

 to the Secretary, Mr. Glaisher. The clouded state of the atmosphere, both here
