120 TWENTIETH ANNUAL REPORT OF THE REGENTS. 



REMARKS FOR THE YEx\R. 



January 2. — A beautiful lunar rainbow surrounded the moon at 9 P. 

 M. about 8° in diameter. A slight cirro-cumulus or sondercloud passed 

 over the surface of the moon which, within the extent of the rainbow, was 

 entirely obscured by the iridescence of brilliant colors ; from the outer 

 border of the moon to the inner border of the orano:e color it was almost a 

 pure silver white, composing ont-half of the diameter of the bow. The 

 balance of it was of the same arrangement of colors and vividness of 

 appearance of those that are usually seen in the summer months near the 

 surface of the earth just as a shower is passing away. The peculiarity of 

 the rainbow was its entire circular form and brilliancy of colors. 

 January 8. — Highest barometer observed in this vicinity, 30.42. 



" 20. — A thunder shower at 12^ A. M. attended with lightning, 

 high wind and rapid falling of the thermometer. The storm moved along 

 the axis of storms of this locality at the rate of forty-five miles per hour ; 

 severe cold and high wind continued through the day. 

 January 24. — Severe north-east snow storm. 

 February 14. — Fine sleighing ; snow storm during the day. 



" 15. — Very cold; mock suns and fine solar halos at 9 A. M. 



Coldest day of the year. 

 " 16. — Lowest thermometer on record in Toledo. 

 " 22. — Rain A. m. ; blue-birds seen. 

 " 24. — Robins made their appearance. 

 March 6. — On the forenoon of the 6th a beautiful set of halos and par- 

 helia were seen for several hours. The haloes were of the two kinds — 

 those of 22° in diameter and those of 46" — some finely colored and some 

 not. The parhelia, ov mock-suns, nearest to the sun were vertical with 

 the observer, and colored — the others not — and were situated at the inter- 

 section of the halos of 46°. The first or inner halo was highly colored 

 and 22°; the next presented the most remarkable appearance ever observed 

 — as seen, it was elliptical and colored ; its long diameter was about 30 to 

 36°, and lateral with the beholder; its short diameter intersected the par- 

 helia of the inner halo of 22°, both above and below the sun. The next 

 halo surrounded the sun of 46° of diameter, colored laterally, below inter- 

 secting the horizon and above reached well nigh the zenith. The next was 

 uncolored, perfect, and of 46°, extending from the sun to beyond the 

 zenith ; it evidently was a secondary halo of the large or outer halo that 

 encircled the sun. At the points that it intersected the colored halos it 

 produced faint but perceptible parhelia, or mock-suns ; laterally with the 

 sun there were also partial uncolored halos made from the larger one, 

 whose segments were of halos of 46°; these segments, where crossing the 

 colored halos produced faint and almost imperceptible mock-suns, so that 

 at one time there were to be seen six haloes, perfect and imperfect, and 

 ten parhelia, or mock-suns, colored and uncolored. 

 March 13. — North-east rain ; ice moving in the river. 

 " 14. — Ice nearly all out of the river. 

 " 20. — Thunder shower ; very sharp lightning. 

 " 28. — Good sleighing on the pavements; sleighs out.
