vestigations may be carried on which could not be brought 

 to successful conclusion at the central office in St. Petersburg. 

 This new physical observatory consists of a principal stone 

 building, with a high tower for anemometric observations, 

 and contains physical, chemical, and photometric observato- 

 ries, workshops, etc. A magnetic apparatus of the most 

 complete nature is established in a subterranean cellar room. 

 Dwellinirs for the officials will also be erected. The entire 

 cost will not be far from one hundred thousand dollars in 

 gold. The erection of the new building will begin in the 

 spring of 18*76. The annual appropriation for the institution 

 will amount to thirteen thousand dollars, while the similar 

 appropriation for the central institution at St. Petersburg, 

 which amounts to thirty-six thousand dollars, will not be di- 

 minished, in order that it may carry on to completion the 

 great works already begun. Yien^ia Zeitschrift fur 3Iete'

THE HURRICANE OF SEPTEMBER 9tH TO IVtH, 1875. 



The hurricane of vSeptember 9th to 17th is described in the 

 Monthly Weather Review of the Army Signal-office as one of 

 the most violent that has occurred since the establishment 

 of the Weather Bureau. It was first observed in latitude 

 13 north, longitude 17 east from Washington, and appears 

 to have orio-inated to the east of Barbadoes. Passing: thence 

 toward the west-northwest, its path curved around, striking 

 the coast of Texas, whence it moved toward the northeast 

 until it disappeared in latitude 38 north, longitude 6 east. 

 On the 14th the morning reports announced that the centre 

 of the storm had already passed to the westward of Key 

 West and Havana. Very perfect records of the changes in 

 the barometer and winds have been preserved at the Galves- 

 ton and Indianola stations, at which place it was at its height 

 on the 16th and 17th. The lowest barometers were, at Gal- 

 veston 29.04, and Indianola 28.90. The maximum velocity 

 of the wind at Galveston was sixty miles per hour, from the 

 southwest and west. The maximum at Indianola was eighty- 

 eight miles per hour, from the northeast, as registered by the 

 anemometer. This instrument having: however been de- 

 stroyed by the continued gale, it was estimated that the ve- 

 locity subsequently attained one hundred miles per hour.
