158 Meteorological Observations for June 1829. 



Note. — The accuracy and judicious arrangement of the instru- 

 ments used, which are very essential to the purposes of meteorology, 

 the able hands in which they are intrusted to register the observa- 

 tions, and the opportunities that will be afforded the observer in so 

 eligible a situation, to ascertain the effects of heat or cold, wind, 

 rain, and drought, on the various fruits and vegetation, will ulti- 

 mately be found beneficial to the Horticultural Society, by the ex- 

 perience they will gain year after yetfr in providing as much as pos- 

 sible for the preservation of those things against the vicissitudes of 

 a very changeable climate.

General Observations. — The first part of this month the fruits and vegeta- 

 tion made but little progress in growth, from the want of moisture; but 

 the wheat, which came into ear the first week, preserved a verdant and 

 luxuriant appearance ; it is now turning yellow, and will be fit for the sickle 

 in this neighbourhood in three weeks, with genial weather : the last fort- 

 night was contradistinguished by frc(iuent intervals of warm showers of rain, 

 the bcnelicial effects of which on the productions of the earth may be seen 

 even by casual observers. 



On the 1st instant distant thunder was heard here, and light showers fell 

 at a distance. On the 3rd the thermometer in the shade rose to summer- 

 heat, when it siiowcd the maximum temperature for the month. Early in 

 the morning of the 7th a very white hoar frost appeared in the grass fields, 

 and was brought on by a cold N.E. wind under a clear blue sky, and a pretty 

 high atmospheric pressure. 



In the evening nf the 9th a large halo appeared round the moon, and 

 set with it, which indicated a humid chance in the slate of the atmosphere.
