the liiuar shadow. At the time of totality to remove the eiilarger 

 and pliotograph the outer and inner corona with the h3'drogen 

 flames. Operated by Dr. Marsh. 



2. A 3-inch Dollond telescope, 45-inch focus, -with camera at- 

 tached, for photographing" the phases. Also the coronal streamers. 

 Operated by Mr. Jenkins. 



3. A prismatic camera attached to the driving clock of the 5- 

 inch Brashear. The lens was loaned by Dr. Caviller, of Hamil- 

 ton ; the grating by Father Kavanagh. The arrangement was to 

 photo on a 5x8 plate at totality the eclipse in entirety, the stream- 

 ers, flash spectrum, and the first and second order of spectra. 

 Operated by Mr. Jenkins. 



4. The Potter lens, 2^-inch aperture, 2-foot focus. Equa- 

 torially mounted, the equatorial head loaned by Dr. King, fitted 

 with negative enlarging lens. Dr. Johnson, editor of tlie Tech- 

 nical World, of Chicago, operated this instrument. 



5. A compass transit carefully adjusted, operated by Dr. 

 Marsh. . Cave magnetic deviation of 36.52 N.W. and a fluctuation 

 of the magnetic needle, during totality, of some six or eight min- 

 utes. It was too dark to read the verniers. 



We must not forget to say that the little metronome lent us bj' 

 Miss Jessie Williams, of Hamilton, was set in a prominent place, 

 and beat the seconds, not only for the Hamilton contingent, but 

 for the 45-foot camera, and Mr. J. R. Collins, of Toronto. 



In addition to the instruments above named others were in- 

 stalled. Mr. J. R. Collins, of Toronto, secretary of the Royal So- 

 ciety of Canada, had a lo-inch reflector, constructed after his owmi 

 device, with which he expected to make a continuous photographic 

 record of the eclipse. 



Prof. Chant, of Toronto University, had a polariscope for 

 visual purposes and a photopolariscope mounted on Dr. Marsh's 5- 

 inch equatorial. 



Rev. Father Kavanagh had a very ingenious device attached 

 to a 31^ -inch telescope, by which he was to draw the corona.
