At the second International Exposition at Paris his meteorograph was quite a feature. The _Kölnische Zeitung_ wrote, on March 2, 1878: “Visitors of the Italian Exhibition, at the second World’s Fair in Paris, could see the marvellous instrument which does the work of ten observers and surpasses them in accuracy. At the same time they could obtain all needed information about details and scope of the meteorograph from the exhibitor himself; for _Secchi_ was there daily, devoting several hours to answering questions in any of the civilized languages of Europe. It is peculiarly interesting to observe the silent movement of the hands working day and night like registrars of the natural forces, and recording for every quarter of an hour with the utmost accuracy all changes in temperature, in humidity, every variance of the wind, any movement of the mercury in the barometer. Even the force of the wind and the time of rain is registered by this wonderful instrument.” The inventor, out of 40,000 art exhibitors, was awarded the great golden medal. He also received the insignia of an officer of the French Legion of Honor, while the Emperor of Brazil appointed him an officer of the “Golden Rose.” The French scientist _Moigno_ writes of _Secchi_: “_Secchi_ was very pious, and as a worker he knew no limits. He was ever ready to evolve new scientific plans, to enter into new and long campaigns of observation. The mere list of his 800 works reveals him as one of the most intrepid workers of our century. And let this be considered: every one of these writings, no matter how brief, was the result of subtle and difficult researches and observations. And after devoting the day to arduous writing, he passed the night searching the skies” (_Pohle_, P. Angelo Secchi, 1904, 191). In the nineteenth century, too, astronomy has not failed in its mission of leading to God. A long list could be named of believing astronomers of great achievements. For instance, the Roman astronomer _Respighi_ (died 1889), a resolute Catholic. And _Lamont_, Director of the Observatory of Munich, whose Catholic orthodoxy was generally known. _Heis_ (died 1877) likewise was a zealous Catholic: when he had finished his map of the sky, after 27 years of hard work, he sent one of the first copies to _Pius IX._ The astronomers _Bessel_ and _Olbers_ speak in their letters of God, of the hereafter and Providence, in a way that has nothing in common with materialism.
