372 John Adie, Esq., on the 



scope was provided with three sun shades, and a free open- 

 ing ; two were red, of different shades ; the third, light 

 green, and all so arranged in an eccentric that by a slight 

 touch of the finger any one of these could in an instant be 

 brought between the eye and the image formed by the tele- 

 scope. 



The situation selected for making these observations was 

 on the roof or top of the Hotel Goetha Kellare, having round it 

 an iron railing, of which I took advantage in order to give 

 steadiness to my telescope. By placing myself on my back, 

 and holding with one hand the object end of the telescope to 

 the railing, and with the other the opposite end to the eye, I 

 was thus enabled to obtain a position which afforded the most 

 perfect stability to the instrument. And here it may be just 

 noticed in passing, that, should I ever require at any future 

 period to use a larger and more powerful telescope, I should 

 prefer such an arrangement as that now described to any 

 stand to be made use of in the open air. 



In the focus of the eye glass were placed two parallel fibres 

 for estimating magnitudes and distances, the value of the 

 interval between the fibres being found from observed tran- 

 sets of the sun. 



My first observation, previous to the beginning of the 

 eclipse, was directed to an examination of the sun's disk, on 

 which was found, by means of the telescope, only one very 

 small spot on the western limb, about 80 degrees of an arc 

 from the sun's upper point, and about 2 minutes of an arc 

 from the sun's edge. 



Not being provided with a chronometer, I had previously 

 compared my watch with one, and assigned for the com- 

 mencement of the eclipse, 2^ 53"^ 30^ Goteburg mean time. 

 No value, however, is to be attached to this observation, 

 as I felt satisfied that the first contact took place some 

 seconds before the time above noted. The moon passed over 

 the sun's disc, each having a very sharp and well defined 

 outline. A thin cirrous cloud formed over the place of the 

 sun as the eclipse advanced, without however apparently de- 

 tracting from the sharpness of the limbs. At 3^ 27^ there 

 was a marked difference in the amount of light. At 3^ 35™
