The shutter of the Astrographic Dome was blown off into the court at 11^h 32^m/ The wind was blowing 50 miles per hr, the pressure was 30 lbs per sq. ft. The head-piece of the dome fell inside, just missing M^r Davidson, who was printing reticles. The falling shutter struck the roof of the T.C. room breaking a few tiles and coping of the N.W. of the roof. It then fell on to the porch leading into the T.C. room, breaking one pane; it bent the corrugated iron covering in the front court & fell into the court. Niblett & Woodman at once covered the instrument with light tarpaulin, while Simmons procured some heavy tarpaulin from Mess^rs Mowlem & Co. Six of their men, who were engaged on the building of the New Altazimuth with Cross & Barnard firmly lashed this over the opening.

RH says..... Oh dear, disaster strikes again just as Christie has left for his holidays. What is great about this is that not only do we have a photograph recording the incident, but that Dyson tells us that the falling piece of shutter nearly hit Davidson, one of the Observatory's human computers. It's just as well that it missed as this is the very same Davidson who went on to become an Assistant and to head the famous eclipse expedition to Sobral in 1919 at the same time as Arthur Eddington was in Principe, in an attempt to provide observational proof of Einstein's theory of relativity. Eddington, who had been a vocal supporter of Einstein, and Dyson, who had suggested the idea and organised the whole, generally get the credit for this work, but it was the photographs taken in Sobral under Davidson that provided the usable data. Davidson, Eddington and Dyson were co-authors of the 1920 paper on their results.

Tuesday October 30, 1894

Discussed with M^r Skinner (from Mess^rs Troughton & Simms) plans for new Astrographic micrometer and for Photographic spectroscope.

RH says..... On another topic, Graham Dolan has kindly send me an image of the Great Equatorial Building's balcony under construction - see entry for 19 October. He tells me that this picture can be dated to the summer of 1898, so it seems that it took some time to do the work. It is always interesting to see in these old images that, although the Observatory was closed to the public, it was still a sight for visitors to Greenwich Park - even if they were chiefly there for the view down to the river that the people on the benches at the right of the picture are enjoying.

Thursday October 4, 1894

Went to Troughton & Simms about new Astrographic micrometer & new spectroscope. Found nothing had been done in preparing working drawings.

Diaphragm of the Astrographic Micrometer sent to Troughton & Simms to be rouged, as the divisions were very difficult to see against the photographs.

Monday September 24, 1894

Went to Troughton & Simms with M^r Dyson and arranged with M^r Simms for a new Astrographic micrometer for measuring two plates at same time and for a Photographic spectroscope. Also gave M^r Simms a paper for positions of stops in new altazimuth to give a series of adopted azimuths.

Went with the Astronomer Royal to Troughton & Simms’ works. M^r Simms & the Astronomer Royal discussed photographic spectroscope especially the kinds of glass obtainable, & the Micrometer for the Astrographic measures.

Wednesday September 12, 1894

Went to Troughton and Simms’ about alteration of microscope of Astrographic micrometers & Posⁿ microm. of 28ⁱⁿ telescope. Saw the new Astrographic micrometer made for Prof. Turner.

RH says..... Christie is straight back to business after his long holiday. It is nice to see his interest in the instrumentation ordered by Turner, his former Chief Assistant, in his new role as director of the Radcliffe Observatory in Oxford.

Tuesday August 21, 1894

A man called from Mess^rs Troughton & Simms about the Position of the 28 Inch Micrometer. I shewed him the method of illumination used in the Astrographic Telescope. He had been unable to obtain a dark field and illuminated wires in the way suggested by the Astronomer Royal, and wished to use some prisms to reflect the light. M^r Lewis & I discussed the matter with him and agreed that M^r Simms should do it as he liked & alter it subsequently, if necessary.

Frank Dyson, Chief Assistant

Monday July 23, 1894

Went to Troughton & Simms’ in afternoon & arranged about alterations to astrographic micrometer & to position circle micrometer for 28 inch telescope. Ordered a new positive & a new negative eyepiece for 28in telescope power 1000. Inspected new altazimuth, the telescope, axis & circles being mounted in position. Approved of patterns for mounting of collimators. During my absence Minifie the labourer fell from a tree in the garden, from a height of about 25 feet. He fell on his back but, though much shaken, was not seriously injured. He was cutting off a branch which interfered with the sunshine register.

RH says..... Poor Minifie: a near-martyr of meteorological science.

Friday July 20, 1894

Meeting of Boreman Governors at Greenwich at 1. Dinner & reception at Imperial Institute to commemorate 25^th anniversary of telegraphic communication to the far East.The astrographic micrometer taken away by M^r Simms for adaptation of a new millimetre scale, position circle & clamp to plate carrier, and focussing adjustment to microm. microscope.

RH says..... Christie's meeting was of the charitable Boreman Foundation, named after Sir William Boreman who, in the 17th century, bequeathed a school in Greenwich and various to the Drapers' Company. The William Boreman Nautical School was absorbed into the Greenwich Hospital School in 1886 but the charity continued (and still continues) to provide scholarships and other financial assistance.

The Imperial Institute, later the Commonwealth Institute, was founded in 1887 to carry out scientific research that supported agricultural, industrial and commercial development of the colonies and dominions. In 1894 the Institute had just moved into its new buildings in South Kensington. All that survives is Queen's Tower, now part of Imperial College.

Wednesday June 20, 1894

Arranged with Desforges (from Troughton & Simms) for mounting of new glass millimetre scale in Astrographic micrometer.

Dined with Dyers’ Company at the “Ship” returning thanks for the Visitors.

William Christie, Astronomer Royal

Monday January 29, 1894

The laying of Brookes’ electric main was commenced. M^r Henry H. Vincent (stage manager) & M^r H.P. Hall (artist) of the St James’ theatre called with reference to an Observatory scene in a new play. Showed Great Equatorial, Lassell & Astrographic Equatorial. The last seemed the most suitable.

Rebekah Higgitt says.....

Here we find another use for large telescopes - inspiration for theatre design! A review of the "Brilliant First Night" of Henry Arthur Jones's "The Masequeraders" at St James's Theatre in Picadilly in April 1894 can be found online, a performance that was only marred by a "short and weak last act". Presumably it is only coincidence that it was this act that featured the telescope: "The last scene is laid in the observatory on Mont Saint Garidelli, in the Maritime Alps, near Nice. The room is dark, save for a shaft of moonlight which illuminates the large equatorial telescope in the inner room".

Tuesday January 2, 1894

In the evening severe weather, with snow set in. The Astrophotographic Dome was left open by the observer, & on the next morning the telescope & inside of dome were covered with snow, which however had not melted.

Rebekah Higgitt says.......

Bad weather - a perennial problem for astronomers! This image just misses the astrographic dome, which was built above the building off the right (west). It does, however, show the large dome covering the 28-inch telescope with the smaller dome that housed the Sheepshanks telescope in front.
