2*^. That the granulations have been smaller and le?s numerous. 



3"^. That the light-gray colored background seen between the granules 

 has been more c{)iis[)icuous and has occupied more space than 

 usual. 



4". That there are spots, which I have named '' veiled spots," which 

 are seen through the chromosphere which is spread over them 

 like a veil. 



5*'\ That these veiled S|)ots are true openings of the i»hotosphere, like 

 those of the ordinary spots. 



C. That during this period these spots have been larger, darker, 

 and more numerous than I have before seen them. 



7*"^. That the veiled spots are scattered throughout all latitudes, though 

 more complicated in the regions where the oixlinary spots make 

 their appearance. 



8®. That I have observed s^jots at least within 10° of the north 

 pole of the sun. 



9". That the flocculent objects sometimes seen projected upon the 

 umbra and penumbra of spots are the remaining portion of the 

 granulations comj)osing the chromosphere, more or less dis- 

 solved by the forces emanating from the interior of the photo- 

 sphere.
