Perhaps, favoured by some affinity of the atmosphere, its constituent parts are broken up and become gases at this barometric pressure and temperature. We must ask the spirit, if he visits us again." "I wish he would," said Ayrault; "there are lots of things I should like to ask him."
From Encero to the small Indian village of Las Vigas, there are 7500 toises of horizontal distance; and Encero being, according to my barometric measurement, 746 toises lower than Las Vigas, the result, for the mean slope, is only an angle of 5 degrees 40 minutes.
He adduces evidence of an atmosphere, but of an exceedingly scanty one, since the greatest amount he can give to it is "not more than about four inches of barometric pressure as we reckon it"; and he assumes, as he has a fair right to do till disproved, that it consists of oxygen and nitrogen, with carbon-dioxide and water-vapour, in approximately the same proportions as with us.
Featherstonhaugh and Mudge is no more than 1,085 feet. It is regretted that the computations of the barometric and other observations for the determination of the heights of that portion of the country between the valley of the St.
Under the same barometric pressure, consequently at the same height, but thirty degrees of latitude nearer the equator, the befaria of the Silla is often, at noon, in the sun, exposed to a heat of 23 or 24 degrees. The greatest nocturnal refrigeration probably never exceeds 7 degrees.
Above Alta Gracia, near the mouth of the Rio Ujape, I had found the velocity of the Orinoco 2.3 feet in a second; between Muitaco and Borbon it was only 1.7 foot. The barometric observations made in the neighbouring steppes prove the small slope of the ground from the longitude of 69 degrees to the eastern coast of Guiana.
The velocity of the cyclonic currents will depend largely upon the difference in barometric pressure between the storm-centre and the confines of the cyclone system. And the velocity of the currents will determine to some extent the degree of deflection, and hence the exact path of the descending spiral in which the wind approaches the centre.
Indeed, it seems that if the whole earth were covered with an uniform and deep ocean of water, the tides would be excessively feeble. On no other supposition can we reasonably account for the fact that our barometric records fail to afford us any very distinct evidence as to the existence of tides in the atmosphere.
On behalf of the United States Captain Partridge made many barometric observations, while Mr. Johnson took an extensive series of vertical and horizontal angles. His operations were performed in the presence of Mr. Odell, the surveyor on behalf of Great Britain, who doubtless made similar ones, as he visited the same stations with a better instrument and for the same avowed purpose. Mr.
This type of propagation occurs during certain special meteorological conditions, like high barometric pressure and extreme heat. We sometimes hear stations in Malta and Sicily with very loud signals." "In 1966 I built an aerial array consisting of 8 nine-element Yagis for 2 metres with the axis of rotation pointing to the North Star enabling me to track the Moon automatically.
