234 Historical Review of Experiments 



On reaching Geneva, in August, I read my memoir 

 in the presence of Professor Pictet, De Saussure, and 

 various other persons, and at the same time repeated 

 some of my experiments with the thermosc'ope. 



As soon as I reached Paris, in the latter part of Oc-

 experiments which bore a resemblance to some which I

 Sir Joseph Banks. M. Bertholet had at the same time 

 received from England a copy of the work, which was
