On this day (January 11) in the year 1847, the following article
appeared in "The Boston Daily Evening Transcript":

MICROSCOPIC DAGUERREOTYPES. At the suggestion of several friends,
the following brief account is prepared, of some incipient experiments
recently made at my request, by Mr John A. Whipple of this city, for
combining the microscope and the Daguerreotype apparatus. I believe
the attempt has not before been made in this country, and I was not
aware, when commencing these experiments, that the thing had been
attempted abroad. A distinguished foreign naturalist now in this city,
pronounced the results produced here superior to any he has seen in
Europe.
We used an excellent compound microscope, made by Oberhauser, of
Paris. We have used it both with and without the eye glass, but we are
not yet able to decide which method is best. The first object tried
was a spider's claw, measuring by the micrometer 1 60 of an inch in its
longest dimension. On removing the plate, we had the pleasure of
seeing on it a beautifully defined figure of the object magnified 75
diameters, or superficially 5625 times. The only defect was a slight
excess of light in the centre. We modified the arrangement, and tried
the eye of an insect. A correct figure was obtained, but with the same
defect. Suspecting what proved to be the true cause of the difficulty-
-reflected light--we still further varied the arrangements, and tried
the Pulex. We had the satisfaction on this trial to obtain a well-
defined Daguerreotype impression of the object entirely free from the
defect which marred the others. Several other objects have been tried
with equal success. Even the invisible may be Daguerreotyped, enlarged
almost indefinitely.
I am under great obligation to Mr Whipple, for the skill and
industry with which he has aided the experiments. In the midst of
pressing engagements with visitors to procure his excellent miniatures,
he has cheerfully devoted himself, and his apparatus combined with my
microscope, to this work. He is now preparing a small cabinet of
Daguerreotypes of minute objects in Natural History, to be exhibited at
his room, 113 Washington street.
As this use of the Daguerreotype gives enlarged figures of the
minutest objects with unerring truth, I hope it may aid the naturalist
in revealing the "elegantly little," and writing it legibly in enduring
letters of light. Prevented as I am by other engagements from devoting
time to these experiments, I hope Mr Whipple and others will prosecute
them until the process is made easy in practice and perfect in
execution. The first specimen obtained on the 21st of December, 1846,
may be seen at my school-room in Central Place.
