'Histological'
|
|
Signed 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880'. This stand is unusual in that it has a Meyrowitz signature but straight rack and pinion which may make it earlier than the other Meyrowitz-signed stands.

Note the single swinging tailpiece
which carries both the condenser assembly and the mirror, and the flat tripod foot. It is signed: 'BULLOCH'S PATENT, E. B. Meyrowitz,
MAKER, NEW YORK, PAT'D 1880' although the '1880' looks to be crudely
added, and would be incorrect on any account, as there is no Bulloch
patent in 1880 for a microscope, as it was in 1879. |

HISTOLOGICAL
|
|
Note that this microscope has a single
swinging tailpiece which carries both the condenser assembly and the
mirror, and the asymmetrical
flat tripod foot. The foot is signed 'Bulloch's Patent, E.B. Meyrowitz
Maker, New York, Pat'D 1879'. This example has a glass-covered glide
stage ('Sliding Object Carrier'), with single pressure point, but the
slide carrier is missing. The word 'maker' associated with Meyrowitz's
signature implies this stand was made after Bulloch's death, about
1891, but might also simply be a Meyrowitz claim tolerated by Bulloch
at the time. |

This instrument has a similar but NOT identical
signature to the other number 201. It is signed: 'E. B. Meyrowitz,
MAKER, NEW YORK, Bulloch's Patent, 1880' with the E. B. Meyrowitz in
script. The number 201 is engraved on the edge of the same toe as the
signature. The number includes a 'script' type of numeral instead of a
block letter type of 2, as is found on the microscope which is the next
entry. |

BACTERIOLOGICAL (BIOLOGICAL NO. 2)
|
|
Signed 'E.B. Meyrowitz Maker, New York, Bulloch's Patent, 1879. Note the words 'Bulloch's Patent, 1879' are stamped rather than engraved .
Also note the third version of the Bulloch Mechanical stage
with concentric horizontal controls projecting from the top of the stage. This stand also features the improved substage, designed specifically for the Biological No. 2, and noted for the first time in the Journal
of the RMS, in 1884, Vol V4, part 1, sect2,page 279. The substage was later changed by Meyrowitz who added the rack and pinion offset to the iris. This is seen on other examples of the same microscope, as in
serial number 211 listed below. More interesting is the use of spiral
or diagonal rack and pinion coarse focusing, a feature
invented by Swift after 1890. Note that there is another
microscope with the serial number 201,
also with Meyrowitz
signature, though the signature is slightly different. Differences
include the 'script' for the older 201, vs block numbers for the later
version. Also the words 'Bulloch's Patent' appear to be stamped, as
opposed to actually engraved, albeit in a similar font, on the older
201. In addition, the patent date on the older example is incorrectly
listed as 1880, whereas the newer example has the correct date of 1879. |

Note the nickel-plated brass gliding slide
carrier and an extra knob at the top of the optical tube
which clamps the drawtube in position. This instrument has the same
advanced substage and also has spiral (diagonal) rack and pinions for
coarse focus and the substage focus as the late 201 above. |

Signed: 'E. B. Meyrowitz, maker, New York, Bulloch's patent 1879, no. 205' |
This microscope was part of Eli Buk's collection and
sold at auction (lot #713) upon his death in 2013. This is one of the
instruments sold by Meyrowitz after Bulloch's death and has the same
serial number as one made by Bulloch himself, but was sold
much later. |

|
For an almost identical microscope see number 201
above.
|
This microscope is virtually identical to number 201,
except the stage has been replaced by a pear-shaped platform and a
Bausch & Lomb accessory stage. There is an associated eyepiece
micrometer (maker unclear), and a vertical illuminator (not by
Bulloch). The substage assembly, modified by 'Meyrowitz,' is exactly
the same as in number 201. Another addition is a clamping lever at the
trunnion joint to more securely fix the inclination at a chosen angle. |

'PROFESSIONAL' (2 PILLAR)
|
|
This microscope has the later straight tailpieces, and
the third version of mechanical stage. The equiaxed foot has a circular
plate but with calibrations. This is a monocular
scope. Signed: 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880' This microscope also has a diagonal
rack and pinion, which means it is a later model, likely made after
Bulloch's death. Another distinguishing feature of this particular
microscope is the lack of the angular support plate from the limb to
the stage. |

There is only one flat and straight

underside of the stage. |
This microscope was sold on Ebay, and the seller was
kind enough to allow me to use his images here on my website; it now
resides in the Brooks Collection. |
