supposed facts as a proof of the inheritance of acquired char- 

 acters is inadmissible. 



This type of corn is very much more indented than Correns's 

 " Leucodon, " which is properly a half-dent form. 



2. — (Y. D.) " Riley a favourite" yellowdent corn, from Web- 

 ber. Deep yellow in colour and even more indented than the 

 W. D. It gave a poorer crop than the latter, and was only 

 grown for two generations. 



3. — (W. S.) "Moor's Concord" white sugar corn, from 

 Webber. A form corresponding to the "Dulcis" of Correns. 

 and yielding typical hyaline, much wrinkled, sugary grains 

 without pigment. Only very small plants and poor cobs were 

 obtained. 



4.— (G. W. S.) Giant white sugar corn obtained from a 

 seedsman in Philadelphia. Similar to the above in essen- 

 tial characters, but the grains were less hyaline and occasion- 

 ally a few of them showed some approach to starchiness. Tin- 

 strain yielded much larger plants and finer cobs than the last 

 mentioned. 



5. — (B. S.) "Black Mexican" sugar corn, from Webber. 

 This corresponds to the " Cceruleodulcis " of Correns. The cells 

 of the aleurone layer contain a deep purple pigment which 

 makes the grains appear almost black. In other respects 

 this form closely resembles W. S. In the Ceylon climate it 

 fared even worse than that variety. 



6. — (W. P.) White pop corn from Philadelphia. Very hard 

 round grains of a hyaline nature, without pigment ; cobs and 

 grains very small. 



7. — (Y. P.) Yellow pop corn from Philadelphia. Resem 

 bled the above, but the endosperm was of a clear bright 

 yellow colour. 



Besides the above, some strains of pointed pop corn, as 

 well as the very large starchy variety known as Cuzco, were 

 tried, but failed to produce fruit. 



8. — The strain commonly grown by natives in Ceylot 

 was of the flint type and exhibited the colours white, blue.
