METEOROLOGICAL OBSERVATIONS. 171 



before. Lime water required 390 measures for neutraliza^ 

 tion. Tested that in the receivers at 5 p.m. of the 8th 

 instant ; thermometer 75°. This required 210 measures of 

 the acid for neutralization, leaving 180 for carbonic acid, 

 being double that before, or about 1 in 3920. 



Experiment rv.— October 11th ; 4| p.m. Collected air 

 as before ; there had been much rain during the day, but 

 it was fine and calm after 3 p.m. ; thermometer 77|°. In 

 this case the lime water took 375 measures for neutraliza- 

 tion. Tested that in the receivers on the 18th; thermo- 

 meter 75°. The 1500 grains in the receiver required 280 

 grains for neutralization, leaving 95 for carbonic acid gas. 



In . the experiments 1, 2 and 4, the gas is consequently 

 about 1 in 8000 ; and in the 3rd 2 parts in 8000. In the 3rd 

 the receiver was out during the rain, but so placed as to 

 prevent its entrance. The air in 2 and 4 had traversed the 

 small island of St. David's, distant perhaps 1^ of a nule, 

 thinly inhabited, and thence the inlet of the sea, St. George's 

 Harbour. 



The acid was pure, brought out with me for particular 

 experiments. 



Looking to the general result, and in number 3, the 

 quantity being double, inaccuracy of observation of the 

 measures might possibly have led to the differences. 



MISCELLAIJEOUS NOTES, ETC. 



Air-blown Fish. — It is the custom of Bermuda fishermen, 

 when they take large fish, such as Groupers and Kock fish, 

 to pass a small rope through their gills and tow them alive, 

 into port. The fish thus brought to market are almost
