obovate. Apiculate long clawed, with broad green centres 

 and white margins. 



" 6th. Leaves ovate, long acuminate, petioled. Petioles 

 ascending, widely spreading, seven inches long, inserted 

 about two inches above the root stock and six or seven 

 inches below the tlower. Sepals normal. Petals green, 

 with white margins. 



"All the flowers seemed to be perfect, some having 

 a sterile filament, which might be due to accident." 



No. 6 was potted and photographed by Mr. Dickson. 

 When photographed the stem was 10 inches high, the 

 peduncle being 8 inches in length. The petioles were 8^ 

 inches long; leaves 2| inches long, 11 inches broad, long- 

 acuminate. 



A remarkable form, sent from Niagara by Mr. Cameron, 

 has the petals changed into petioled leaves (petioles more 

 than an inch long.) Mr. Cameron has also sent me a 

 photograph of a very large flowered plant with 21 pure 

 white petals. It was found on Navy Island, Niagara 

 Eiver, by Mr. Cameron in 1896. He transplanted it, and 

 last summer two flowers were produced, each with 21 

 petals. Mr. Cameron also reports a double yellow-flowered 

 dwarf specimen from Niagara Falls, but this is probably 

 some other species. 



Crystallised Pyrrhotite from Frontenac County. 



By Professor Wm. Nicol. 



Among other minerals sent to the School of Mining for 

 identification, was a reddish-colored, coarsely-crystalline 

 marble containing small but well-formed crystals of 

 pyrrhotite or magnetic iron pyrites, closely associated 

 with crystals of apatite and masses of iron pyrites. The 

 crystals were from one to three millimetres in diameter
