The steam communication being shut off, and the steam in the 

 bottle condensed, the stream of air will immediately carry 

 through with it the whole of the mother water from the most

10. Repetition of the Comparison of the Rate of the Mercurial 

 and Spirit Thermometer, 

 Dr Wildt of Hanover has made a new set of experiments for 

 ascertaining the real indications of the spirit thermometer, 

 chiefly with a view to the employment of that instrument in the 

 Register Thermometer of Rutherford. His results, which are 

 stated below, do not differ materially from those of Deluc. The 

 observations are made at intervals of five degrees of Reaumur^'s 

 scale.

xV-MONG the many extraordinary and striking objects in na- 

 tural history which present themselves to a stranger on his ar- 

 rival in Bengal, perhaps none has been more generally remark- 



* This interesting memoir, by my former pupil and very intelligent friend 

 Dr Adam, is extracted from the 1st volume of the Transactions of the Medi- 

 cal and Physical Society of Calcutta, which has just reached this country. It 

 is a work highly creditable to the Calcutta Society.
