 Andrew Celsius, with that Mr. Miller used in the 

 orangery, and the difference was this : — 

 When Celsius stood at Mr. Miller's was

Botanic Garden at Chelsea. 



In Chelsea lies the famous Botanic Garden, which 

 in London is called Chelsea Physick Garden, which be- 

 longs to Apothecaries Hall in London, was established 

 for the Education of Apothecaries in the knowledge of 

 herbs, and has, as regards herbs, one of the largest 

 collections of all rare foreign plants, so that it is said in 

 that respect to rival the Botanic Gardens of both Paris 

 and Ley den. At least it is believed to overgo them in North 

 American plants. It is laid out at Chelsea [T. I. p. 456], 

 a short English mile from London, because a great 

 many plants cannot thrive in London for the coal-smoke. 

 The river Thames flows past it on one side. On the 

 opposite side lies the orangery full of all such foreign 

 plants as cannot stand constant exposure to the open air. 

 Among other foreign trees which are found there are 

 four Cedars of Lebanon, which stand out in the garden 

 and are now as large and high as our largest firs, Purur, 

 although they were not planted there before the year 

 1683, and stand there in a very meagre earth. The 

 ground for this garden has been presented to the 



* Miller's was apparently a differential Thermometer. One was 

 invented before 1676 by Johann Christoph Sturm, Prof, of Mathematics 

 at Altdorf. [J. L 1
