Scientific apparatus and instruments
Handwritten letter from John Edward Cullum, Westwood, Cahirciveen, County Kerry, to George F. Fitzgerald, dated 24 February 1892. Cullum describes the process of moving equipment to Caherciveen and asks Fitzgerald for money to cover the cost. 4pp. Transcription: “Dear Professor Fitzgerald, You will see by the heading of this that not yet quite established in my new quarters, I am undergoing the process, and I hope a few weeks more will see me safely through it. Mr. Whipple of Kew comes early next month to assist me in the anxious task of removing my self-recording Instruments, as the difficulties of the Conveyance of the property have at last been overcome. As this was anticipated months ago I began with the Magnetic house and have got it on its new site and taken preliminary observations in it. I only lost one month’s record, and that was caused by the bad weather preventing it being towed up, for on discussing the matter with the builder he advised me to try that course, as the house being put together by copper nails and double sheeted he feared it would cost more to take asunder and re-erect than removing it bodily and floating it up to Caherciveen. This he very successfully did, but owing to the delay and the number of hands needed he has just sent me in a bill for £9.19.6. This appears to me a very large amount, but it is well done and the building has not received a scratch. Do you think you could get that amount for me? I am heartily sorry that I should have to ask you for it, but this removal, with other matters, has crippled me for a time, but I shall not I think have to ask you for any more. I had the pleasure lately to send Prof. Reicker my results for comparison with his, and also to a German who wanted them for the same purpose. I am pleased to find they are likely to be appreciated, and if at any time recording Instruments would be considered to be worth the expense. I would welcome them, and do all in my power to make them a success. Yours very truly, J. E. Cullum The Chronometer is a beauty, and goes well.”

Magnetic science
Handwritten letter from Ettrick W. Creak to George F. Fitzgerald, dated 16 November 1886. Creak discusses the increasing changes in the field of magnetic science as well as instruments he believes are needed for further advances. 4 pp. Transcription: "Dear Professor Fitzgerald, I have been absent from London for ten days and unfortunately your letter was not forwarded to me as you should been answered much sooner. I am glad to hear that you have discovered an enthusiastic magnetic observer at Valentia as eventually he may be of help to magnetic science when most wanted. With regards to the fortnightly observations at Valentia, I hardly think they would come up to modern requirements . With the general knowledge we [can?] process of the Earth's magnetic state at given [spaces?], I have come to the conclusion that we require something very [exact?] for further investigations into the subject. The degree of precision I would [?] advocate is nothing less than that derived from self registering instruments - for Declination Horizontal & Vertical intensity accompanied by an Earth currant apparatus. This latter I consider an important addition as we have so little information therein. The magnetic instruments of the Kew pattern. As a preliminary to the most excellent way, Mr. Cullum might be given a differential declination magnetometer which he might observe hourly (absolute time) for 24 hours every fortnight which compared with Kew would give a general idea of the relative motions of the [?] of the [?] places Kew and Valentia. If his zeal also carried him so far he might make numerous eye observations in days of undoubted disturbance. Preliminary observations of this kind would probably tell us whether the expenses of the self registering instruments was worth incurring. Fortnightly observations of [?] the three elements would furnish good value if carried out through the year, and furnish data for secular change in after years. I am glad you are [?] Cork on the question of a Naval observatory. Is the trade there large enough to support it without Government aid? Your Sincerely Ettrick W. Creak"

Handwritten letter from Ettrick W. Creak to George F. Fitzgerald, dated 22 October 1886. Creak discusses his observations concerning magnetism in relation to distance. 4 pp. Transcription: "Dear Professor Fitzgerald, I am much obliged to you for your kind offer to make observations of the magnetic elements but considering that you have so long dis-continued the regular observations I can hardly ask you to start afresh even for a week. I am very sorry your intended magnitude survey of Ireland came to naught as it would have been useful in many ways especially in the reconstruction of our chart of Magnetic Declination so important to navigations approaching the English Channel and Irish Coasts. I have a large number of observations which would [be a?] bringing up to date if I only knew really good values for the secular change. Independent observations made at different spots in the same neighbourhood are often most misleading and nothing but continuous observations of the same spot for about 15 or 20 years will give me the annual change as accurately as I desire. I have Greenwich and Kew and Stonyhurst very satisfactorily but I am anxious to obtain the secular change at places on or near a line roughly drawn from Stonyhurst to Berehaven as from my present values the amount of secular change decreases in that direction becoming zero [and?] a line drawn from Newfoundland to the Cape de Verde Islands. I shall however be very glad of any observations from Ireland such as you have so kindly offered to obtain if possible. Yours Sincerely Ettrick W. Creak"
