(1877) | FIRST PRODUCTION OF 'A 1' CONGRESS STAND |
1878 | AM J OF MICROSCOPY AND POPULAR SCI | III | 1 | 7-10 | Engravings of the the first version of the Congress (with dual swinging tailpieces but not the saddle support to the stage) . There was no control for locking the rotation of the pillars on the foot. This publication does not state when the first Congress was first made; this was reported in the JRMS in 1880. |
1877 | FIRST PRODUCTION OF 'A 1' CONGRESS STAND |
1880 | JRMS | III | PART 2 | 1073-1080 | States that the first version of the A1 Congress stand was first made in 1877 (p 1073) and shows the engravings of the first version. This shows the microscope with dual swinging tailpieces but not the saddle support of the stage, and also lacks the control for locking the rotation of the pillars of the foot.It then shows the later c 1880 version with the saddle stage support feature in engravings on p 1077-78. |
1878 | BULLOCH LETTER TO EDITOR NOTING SEPARATE SWINGING TAILPIECES | 1878 | AM J OF MICROSCOPY AND POPULAR SCI | III | 3 | 67 | Bulloch's response to Zentmayer's letter claiming providence of the swinging substage; Bulloch noted it was the separate swinging arms that he had patented, and also claimed he had made swinging substages before Zentmayer. |
1878 | EXHIBITION OF SECTOR MICROSCOPE | 1880 | JRMS | III | PART 2 | 1067-1068 | The sector microscope was not pictured in either of the Bulloch Catalogs and was never seen in an advertisement. It was said to have been first exhibited in 1878. |
c 1879 | BIOLOGICAL MODEL FIRST MADE | 1880 | JRMS | III | PART 2 | 1078-1080 | This article pictures the Biological and states " it is a more recent stand" than the Congress. It states it was patented in 1879, but of course that is not quite accurate as it was the dual tailpieces that were patented and the patent shows the Congress. It notes the tube length is five inches. |
1879 | 1879 PRICE LIST LISTING THE CONGRESS, SINGLE PILLAR PROFESSIONAL, AND BIOLOGICAL | 1880 | THE MICROSCOPE AND MICROSCOPICAL TECHNOLOGY | 2nd Ed | APPDX | 660 | This short list of Microscopes is the last entry of
Manufacturers in the English translation of Frey. Importantly it describes Bulloch's three key stands of the time: The A1 Congress, The Professional, and the Biological . It clearly desribes the large early single pillar version of the Professional stand as seen on this website. |
1879 | U.S. PATENT OF THE DUAL SWINGING SUBSTAGE TAILPIECES | 1879 (MARCH 27) | US PATENTS | PATENT 215,878 | The original patent showed the new form of long lever fine focus, and dual swinging tailpieces but not the saddle mechanism of stage support. One of the interesting features allows independent rotation of each tailpiece without disturbing the movement of the other, because they are isolated from each other via a fitting that is situated concentrically but inbetween the two. | ||
1879 | FIRST EXHIBITION OF THIRD FORM OF MECHANICAL STAGE WITH CONCENTRIC CONTROLS PROJECTING UPWARD FROM THE STAGE, PERMITTING 360 DEGREE STAGE ROTATION. ALSO MENTIONS THE "CONGRESS Jr" STAND | 1880 | PROC OF NAT MICROSCOPICAL CONGRESS | -- | -- | 86 | This was the first American exhibition of the third form of Bulloch's mechanical stage, and although he did not claim to have invented it, it was an elegant form. The curious reference to "one of his smaller stands, the Congress Jr is also noted, but only in reference to the ease of changing substage apparatus, while maintaining centration. |
1880 | DESCRIPTION OF FIRST VERSION OF HIS LITHOLOGICAL MICROSCOPE | 1880 | AM J OF MICROSCOPY AND POPULAR SCI | V | 256 | This stand had Bulloch's standard features and in addition vernier readout for stage rotation, separate fittings for the substage polarizer and condenser above, the analyzer which slid in and out at the bottom of the optical tube above the objective, with facility for a waveplate to fit there also; it also could be fitted with a goniometer eyepiece with analyzer if desired. A photograph of this instrument in a later issue of the American Geologist reveals this instrument identical to the Professional Model of the time, except for the fittings mentioned . This photograph can be seen next to a regular Professional model on this website. | |
1880 | HISTORICAL REVIEW OF THE FIRST AMERICAN PETROGRAPHIC MICROSCOPES, INCLUDING NUMBER 139 OF BULLOCH | 1889 | AMERICAN GEOLOGIST | III | 225-228 | This is the story of the first American-made petrographical microscopes. It states that Bulloch's number 139 was the first ever made and then refers to subsequent improved versions. A photograph of number 139 is shown; this stand is the stand referred to in the 1880 Am J M and Pop Sci article from 1880, and sent in August of 1880 the University of Minnesota. It reports that this stand was exhibited at the Detroit meeting of the Am Soc of Microscopists on August 17 1880. It states he next made a 'more elaborate' instrument for J.H. Caswell. A third and even more elaborate model was then described his latest and most elaborate Lithological to date. illustrated with an engraving; This was a double pillar design with straight tailpieces, and a very complicated stage, which was the major difference in this stand. That stand was numbered 363. | |

c. 1881 | EXHIBITION AT MEETING OF THE THIRD FORM OF BULLOCH MECHANICAL STAGE, AND ALSO OF THE 'CONGRESS JR' STAND | AUG 1881 | PROC AM SOC MICROSCOPISTS | 4TH ANNUAL MEETING | - | 86 | Note that Bulloch exhibited at the meeting his third and latest version of mechanical stage, the concentric controls projecting abovethe stage to allow 360 degree rotation. It also mentions exhibition of the 'Congress Jr' microscope. |

substituted American stands for the Continental versions
because Continental stands were 'not available here.' |

1887-8? | BASTIN-BULLOCH MICROSCOPE | 1887 | THE WESTERN DRUGGIST | IX | 12 | 420 | According to The Western Druggist, the microscope was being manufactured 'on the order of' the magazine and were to supplement a series of articles on Vegetable Histology to start with the January 1888 article. |
