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

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



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

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

 They found the supposed solar envelope to be of the same eruptive nature as the vast provisions from it, and to be made 

 up of congeries of minute flames set close together like blades of grass.' Miss Agnes M. Clerke.
