1858/01:  No major changes from Partagas and Diaz's (1995a) analysis.  No track available, only one point.  Storm is determined to have reached hurricane status based upon observations from ship "L. H. Sampson".

1858/02:  No major changes from Partagas and Diaz's (1995a) analysis.  No track available, only one point.  Storm is determined to have reached hurricane status based upon observations from ship "Shelter".

1858/03:  Only major change to Partagas and Diaz's (1995a) analysis was to extend the track 12 hr into Canada to account for observations in Maine. Utilized the northern wind-pressure relationship of hurricanes for winds at landfall.  A peripheral pressure reading of 978 mb (around 17 UTC on the 16th) suggests winds of at least 75 kt - 80 kt chosen for the best track.  Central pressure observation of 979 mb gives 74 kt, for the second landfall in Connecticut/Rhode Island - 70 kt is utilized for the second landfall.  Both of these pressure measurements support hurricane status for this storm.  Also used the Kaplan and DeMaria's (1995) inland decay model for winds over New England.  Ludlum (1963) referred to this storm as the "New England Tropical Storm of 1858".

1858/04:  Combined Partagas and Diaz's (1995a) analysis of storms #4 and #5 into one continuous track.  No other changes from Partagas and Diaz's (1995a) analysis.  The storm is determined to have reached hurricane status based upon observations from the ships "Phantom", "Hudson" and "City of Washington".

1858/05: Storm was originally #6 in 1858 in Partagas and Diaz's (1995a) analysis. No major changes from Partagas and Diaz's (1995a) analysis.  Storm is determined to have reached hurricane status from observations from ship "Priscilla".

1858/06: Storm was originally #7 in 1858 in Partagas and Diaz's (1995a) analysis. No major changes from Partagas and Diaz's (1995a) analysis.  Storm is determined to have reached hurricane status from destruction in Bermuda and several ship reports.
