The harsher measures which about that time began to be adopted towards his co-religionists in France are usually assigned as the motive of this step. He now devoted himself during six years to the production of lenses of enormous focal distance, which, mounted on high poles, and connected with the eye-piece by means of a cord, formed what were called "aerial telescopes."5 6  He flipped a switch to display an aerial of the country club on one wall and Dusty's condo on another.31 32  Forms adapted to terrestrial life and to aerial respiration occur in various divisions of Gastropods, and do not constitute a single homogeneous group. Thus the Helicinidae, which are terrestrial, are now placed among the Aspidobranchia.3 4  Again, the practical engineers who are building aeroplanes, and those who are making practical tests by actual flight in those machines, cannot be called "researchers"; that term should be confined to the members, for example, of the scientific committee appointed by the British Government in 1909 to make investigations regarding aerial construction and navigation.2 3  First as regards the transmitting part, one essential element is the antenna, aerial, or air wire, which may take a variety of forms. It may consist of a single plain or stranded copper wire upheld at the top by an insulator from a mast, chimney or building.2 3  It is evident that as the latter increases in bulk, more and more attention must be paid to the dangers of uprooting by winds and storms. Various mechanisms have been adopted in different cases, some connected with the subterranean and others with the sub-aerial portions of the plant.2 3  The,ideal surface of resolution may be there regarded as a flexible lamina; and we know that, if by forces locally applied every element of the lamina be made to move normally to itself exactly as the air at that place does, the external aerial motion is fully determined.2 3  Now it is evident that the aerial motion in front of the lamina is determined by what happens at the lamina without regard to the cause of the motion there existing.2 3  They are generally perennial herbs with a creeping underground stem and erect, unbranched, aerial stems, bearing slender Juncus effusus, common rush.2 3  In Dawsonia superba, a large New Zealand moss, the hydroids of the central cylinder of the aerial stem are mixed with thick-walled stereids forming a hydrom-stereom strand somewhat like that of the rhizome in other Polytrichaceae.2 3  The hawk is aerial brother of the wave which he sails over and surveys, those his perfect air-inflated wings answering to the elemental unfledged pinions of the sea.12 14  (Not to mention the fact that, if the stuff all hits the fan, widget factories like yours would almost certainly be marked with bull's-eyes on the enemy's aerial bombing maps.)13 17
