in uniting totally enclose the chorda. Acaudate Batrachia, 

 according to my own observations. 



c. From two lateral cartilages which enclose the chorda, and also 

 develope the arches from themselves. Higher Vertebrata. 



In terminating this Note, I take the liberty of adding that the only 

 information heretofore existing on the subject to which it refers, is 

 that contained in the very valuable memoirs by J. Miiller* and 

 "Williamson f. The part which each of these has contributed to the 

 elucidation of this subject, will be stated in a paper which will 

 appear in the next Number of the Wurzburg Transactions, to which 

 I refer those who take a more special interest in this matter, and 

 desire to know on what data the results here given are founded. 



VI. " Remarks on the late Storms of October 25-26 and No- 

 vember 1, 1859." By Rear-Admiral FiTzRoY, F.R.S. 

 Received December 22, 1859. 



As many of our Society must doubtless be interested in the nature 

 and character of that storm in which the ' Royal Charter ' went to 

 pieces on Anglesea Island, and as abundant information has been 

 obtained from Lighthouses, Observatories, and numerous private 

 observers, I would take this earliest opportunity of stating that the 

 combined results of observations prove the storm of October 25th 

 and 26th to have been a complete horizontal cyclone. 



Travelling bodily northward, the area of its sweep being scarcely 

 300 miles in diameter, its influence affected only the breadth of our 

 own Islands (exclusive of the west of Ireland) and the coast of 

 France. 



While the central portion was advancing northward, not uniformly 

 but at an average rate of about twenty miles an hour, the actual 

 velocity of the wind circling (as against watch-hands) around a 

 small central " lull " was from forty to nearly eighty miles an hour. 



At places north-westward of its centre, the wind appeared to 

 " back " or " retrograde," shifting from east through north-east, 

 and north to north-west; while at places eastward of its central 

 passage, the apparent change, or veering, was from east, through 

 south-east, south, south-west, and west.
