Meteorology

Declination (Astronomy)
Handwritten letter from John Edward Cullum, Valencia Observatory, Cahirciveen, County Kerry, to George F. Fitzgerald, dated 10 May 1890. Cullum describes his experiments with a declinometer, including initial struggles and variables. 1p. Transcription: "My dear Sir, If I have not written I have not been idle. My first attempts with the Declinometer were failures, and there was no use proclaiming them. The wire you sent me proved to be too weak, and broke in less than twenty four hours. I then applied to the Mechanism [?] at the Telegraph Station, and obtained from Line some fine copper coil wire, but that proved too soft, stretched and broke, and finally he gave one ounce thin brass wire, which I think will do very well. I have now commenced observing, hourly at present, from 8am until 11pm. until I can form some idea of the movements to expect. There is a decided Maximum and Minimum, with a range of ten divisions. I was at first very much bothered with the changes of light, sometimes getting a glare, and then not sufficient illumination. That I think I have now overcome, and have set up a lamp for night work. I think a series of these hourly readings will prove very interesting, if I can only keep them up a sufficient time to be of any use. I hope you have been able to send in the paper on last year’s observations. You will I am sure be very busy with the May Examinations, and I do not intend to trouble you with correspondence, but you may rest assured I am working away steadily, and am very interested in the the Subject. Mrs. Cullum has not been well after her return, suffering from Rheumatism but I am happy to say is much better now, and joins me in kind regards. Believe Me, Yours Sincerely, J. E. Cullum"

Magnets
Royal Dublin Society
Climatology
Royal Meteorological Society
Handwritten letter from John Edward Cullum, Valencia Observatory, Cahirciveen, County Kerry, to George F. Fitzgerald, dated 5 December 1895. Cullum seeks Fitzgerald's advice on where he should publish his research paper on the climatology of Valencia Island, and mentions beginning magnetic experiments with Mr. Watson. 1p. Transcription: "Dear Sir, Do you remember me asking you some time ago about a paper the Met. Office wanted me to write on the Climatology of Valencia Island from 20 years continuous Records? You then thought the Royal Dublin Society would publish it. It has now, under the supervision of Mr. Scott, made such discussions and he thinks scientific interest as to need your opinion whether it should go to the Royal Met. Soc. or even the Royal. Soc. for a larger circulation. In the interest of agriculture and the development of the country its chief value would be to Ireland, but the Meteorologists of the Continent have argued that such valuable data should give a good idea of the Climatology of the Atlantic, and therefore universal value. What do you think? Did I tell you I have sent Mr. Watson the comparison observations I made with him, and the Magnetic work is started again. There is the possibility of me being provided with a new Unifilar, but I expect nothing will be done until the comparison is discussed. With kind regards, believe me, Yours very truly, J. E. Cullum"
Handwritten letter from John Edward Cullum, Valencia Observatory, Cahirciveen, County Kerry, to George F. Fitzgerald, dated 3 March 1890. Cullum apologises to Fitzgerald for giving him incorrect instructions regarding a magnet, and mentions doing work on the house. 2pp. Transcription: "My dear Sir, I am very sorry to have to return you the Magnet; it is entirely my own fault in not telling you the house is arranged to observe it from the North. The bar will therefore have to be fitted to that end, and the scale at the South seeking end. I feel you have just cause to be annoyed with me, for I know how valuable your time must be. You will perhaps be able to experiment with a coating when the bar is dismounted. I find with its fittings it turns the ¼ lb. It is necessary I suppose for it to hang in the horizontal plane to determine the scale value, so I need hardly remind you of that. I am about to tar the roofs, and give the outside wood-work two coats of paint while the weather is dry. What I said the other day about a disturbance on the 15 Feby. is I find greatly due to a mistake in the reductions. I can use the observation, but nevertheless the magnet was unsteady. Apologising for all this trouble I am giving you, Believe Me, Yours very truly, J.E. Cullum"
Magnetism
Handwritten letter from John Edward Cullum, Valencia Observatory, Cahirciveen, County Kerry, to George F. Fitzgerald, dated 8 May 1894. Cullum describes a research paper he has sent Fitzgerald, and asks what form their joint research is going to take going forward. 1p. Transcription: "Dear Sir, I send you a manuscript copy of a further paper of Mr [I Sigelouis?] on the connection between Magnetism and Meteorology which my brother extracted from a larger volume of Reports, too heavy to send by post. I had asked him to forward me any more publications on the subject which might fall under his notice, and as this appears to follow I think your own ideas somewhat I think you will like to see it; but I see Mr. [Hazan?] of the American Weather Bureau predicts “bitter disappointment” to those who are attempting to trace a connection between the phenomena. So you have got a further grant to carry on our observations. Have you decided on what form they are to be? I am quite ready to go on with them if you consider them of any value, or take up another set if I can give the time. With kind regards, Believe me, Yours sincerely, J. E. Cullum"
Chronometers
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.”
