Transcription of Phila. Inq. description of organ, reformatted for ease in reading: 

In the choir gallery is a new organ of excellent tone. It has two ranks [sic] of keys and pedals, 
the keys ranging from Cc to G, fifty-six notes, and the pedals from CCC to C, twenty five notes. 

The great organ contains the following stops – 
    Open Diapason, 
    viol d’amour, 
    stopped diapason, bass, 
    ditto, treble, 
    melodia, 
    night horn, 
    principal, 
    twelfth, 
    fifteenth, 
    sesqui-altera, three ranks 
    and trumpet 
being in all six hundred and forty-eight pipes, all metal except the melodia. 

The swell organ is especially good, and contains the 
    bourdon, 
    open diapason, 
    stopped ditto, 
    Cooper (? copper ?) viola, 
    principal, 
    cornet (three ranks), 
    a trumpet and hautboy, 
being four hundred and forty pipes in (? toto ?), all metal excepting the bourdon and 
stopped diapason. The swell also consists of 
    bourdon, 
    open diapason, 
    stopped diapason, 
    and mixture (two ranks), 
    being seventy-two pipes, the stopped diapason and bourdon being of wood.        

In the pedals there are 30 pipes, both of wood, viz.- 
    Double open diapason 
    and violoncello, 
each 25 feet. 

There are coupling stops to connect the pedal and great organ, the pedal and swell organ 
and the great and swell organ. The organ is, therefore, a 30-stop organ, containing 
entire 1210 pipes. It was performed on yesterday, by Professor M. H. Cross, and the 
choir of the cathedral chapel sang Haydn Mass No. 6, a grand composition: at the Offertory 
Hummel’s “Alma Virgo,” was given and after mass, Haydn’s Te Deum.
