The author, tojjether with Father Secchi, was the chief Italian representative for the stndy of solar spectroscopy, and 

 with Sir Norman Lockyer and ZoUner .shared the honour of having first distinguished cloud- from Hame-prominences. 



' From Father Secchi's and Prof. Respighi's observations were derived the first clear ideas on the general distribution 

 of solar prominences. . . . The structure of the chromosphere was investigated by Prof. Respighi. Sporar and Bredikhine. 

 They found the supposed solar envelo{>e to be of the same eruptive nature as the vast protusions from it, and to be made 

 up of congeries of minute flames set close together like blades of grass.' — Miss Agm's M. Clarke,
