carbonate of soda remains. The solution of the cenanthate forms 

 on cooling a semi-transparent gelatinous mass. 



If oenanthic acid be added to a cold solution of acetate of lead, 

 white flocks of an insoluble salt are immediately formed. Acetate 

 of copper produces an analogous decomposition ; these are acidu- 

 lous salts, which are insoluble in water, but dissolve readily in 

 alcohol ; they may be obtained in crystals by allowing a saturated 

 alcoholic solution to cool. 



It is, however, extremely difficult to obtain by this method the 

 salts free from all adherent acid. If they are washed with alcohol, 

 they are then decomposed into more acidulous salts and subsalts. 



(Enanthic acid appeared to be composed of 



Thirteen equivalents of Hydrogen 13 



Fourteen equivalents of Carbon 84« 



Two equivalents of Oxygen 16 



113 



Its combining weight appears to be about the same, judging 

 from the composition of cenanthate of copper, and supposing it to 

 be composed of one equivalent each of acid and base. 



METEOROLOGICAL OBSERVATIONS FOR MARCH 1837. 



Chisivick, — March I — 5. Bleak and cold. 6 — 8. Fine, but cold. 



9. Cloudy. 10. Cloudy: rain. 1 1. Very fine. 12. Clear and frosty : 

 sleet. 13. Cloudy and cold. 14. Very clear: stormy at night. 15. Bleak 

 and cold. 16. Drizzly: hazy. 17 — 19. Cold and overcast. 20, 21. Snow 

 showers. 22. Cloudy, 23. Cloudy: frosty at night. 24. Very severe frost 

 for the period of tlie season : clear and cold, 25. Cold and dry. 



26 — 31. Excessively dry and cold. 



It will have been observed in the monthly extracts from the Meteoro- 

 logical Journal kept at the garden of the Hoiticultural Society at Chiswick, 

 that the extremes o^ the max. and jnin. columns have hitherto been inserted 

 at the bottom of the columns containing the indications of the barometer 

 and thermometer. Instead of this, in future, at the suggestion of Dr. 

 Lindley, it is proposed to give the means of the respective columns, the ex- 

 tremes of highest and lowest being easily found, if required, by inspection.
