XVII I. Journal of Meteorological Observations made in the 

 Garden of the Horticultural Society at Chiswick during the year 

 1828. By Mr. William Beattie Booth, A. L. S. 



This Journal has been kept in all respects upon the same plan 

 as that for the year 1827, published in the seventh volume of the 

 Transactions. An addition of the means of temperature has been 

 made to the diagram, in which the upper dotted line represents 

 the mean maximum, the lower the mean minimum temperature, 

 and the middle line the mean of the two temperatures. 



The latter corresponds with the statement of the Mean Tempe- 

 rature of the External Air, which is now given in addition to the 

 results included under the monthly remarks, and which is deduced 

 from the indications of the Registering Thermometers of the maxi- 

 mum and minimum temperature in the shade. The situation of 

 these Thermometers is explained at page 103 of the volume 

 above referred to.
