It subsequently appeared thatowing to disturbances caused by Jupiter, the maximum tookplace a day sooner than had been predicted, and the whole thing-was on a much smaller scale than had been expected. In Franceand England ascentsare made every year inorder to observe the fall-ing stars, and this wasalso done in Germanyin 1900. In Germanyastronomers are apt tolook askance at balloonobservations, thoughJanssen and others areof a different opinion. At the conference atSt. Petersburg the com-mander of the SpanishBalloon Corps, DonPedro Vives y Yiches,stated that he intendedto organise a numberof ascents for observ-ing the total eclipse ofthe sun which wouldbe visible at Burgos on.

Yivesy Viches was on board one of them, and with him were a Spanishphysicist and Professor Berson. Several meteorological questionswere to be considered. In the first place it was to be ascertainedwhether there was a decrease of temperature during or aftertotality. Berson stated that any fall in temperature would bevery unlikely, seeing that at a height of several thousand feet 282 AIKSHIPS PAST AND PKESENT. no effect is produced on the thermometer by the setting of theson. It was further to be discovered whether the wind veeredround through almost an entire circle ; the A
