he additional ones which came to
him while there.

At last, by the process of exclusion, the choice was narrowed down to
three names, Schultze, Ladergast, and Walcker, then to the two last.
There was still a difficulty in deciding between these. Dr. Upham called
in Mr. Walcker's partner and son, who explained every point on which he
questioned them with the utmost minuteness. Still undecided, he
revisited Merseburg and Weissenfels, to give Ladergast's instruments
another trial. The result was that he asked Mr. Walcker for a third
specification, with certain additions and alterations which he named.
This he received, and finally decided in his favor,--but with the
condition that Mr. Walcker should meet him in Paris for the purpose of
examining the French organs with reference to any excellences of which
he might avail himself, and afterwards proceed to London and inspect the
English instruments with the same object.

The details of this joint tour are very interesting, but we have not
space for them. The frank enthusiasm with which the great German
organ-builder was received in France contrasted forcibly with the
quiet, not to say cool, way in which the insular craftsmen received him,
gradually, however, warming, and at last, with a certain degree of
effort, admitting him to their confidence.

A fortnight was spent by Dr. Upham in company with Walcker and Mr.
Hopkins in studying and perfecting the specification, which was at last
signed in German and English, and stamped with the notarial seal, and
thus the contract made binding.

A long correspondence relating to the instrument followed between Dr.
Upham, the builder, and Mr. Hopkins, ending only with the shipment of
the instrument. A most interesting part of this was Dr. Upham's account
of his numerous original experiments with the natural larynx, made with
reference to determining the conditions requisite for the successful
imitation of the human voice in the arrangement called _vox humana_. Mr.
Walcker has availed himself of the results of these experiments in the
stop as made for this organ, but with what success we are unable to say,
as the pipes have not been set in place at the time of our writing. As
there is always great curiosity to hear this particular stop, we will
guard our readers against disappointment by quoting a few remarks about
that of the Haarlem organ, made by the liveliest of musical writers, Dr.
Burney.

"As to the _vox humana_, which is so
