appeared at this moment, filling tlie interval between the cusps. 

 This shade was steadily visible until 1^ 55°^ 24'-5, when it broke, 

 and gave place to a very thin bright line which separated the two 

 limbs. At 1"^ 55°^ 51' I noted "interval between limbs very con- 

 spicuous." 



On referring the same evening to the volume of British Obser- 

 vations of the Transit of 1874, the observation of ingress by 

 Commander Wharton, at Rodriguez, was found to correspond in 

 most particulars with mine, and his Fig. 3, on Plate xiv., repre- 

 sents the " shade," as seen by me just before breaking. 



The transit was also observed by the Eev. Charles Faris, Assist- 

 ant Astronomer, with the 7-|-feet achromatic finder (object-glass 

 3"8 inches) attached to the reflector. As the pier hid us from one 

 another, and we "took care to record what we saw without speak- 

 ing, our observations may be regarded as perfectly independent. 

 Mr. Faris did not see any disturbance of the limb at internal con- 

 tact, but saw the cusps meeting at l"^ 55™ 10''6. He had observed 

 external contact at 1^ 35"^ 35'. '.
