Douglas Head to Snaefell, and from Port Erin to Ramsay." This 

 being so, the doubt I expressed (p. 212) is answered. — Arthur 

 Bennett. 



G-ALiuM sylvestre IN OXFORDSHIRE. — This plaut, which does not 

 seem to have been recorded for Oxfordshire, was found during a 

 recent excursion of the Toynbee Natural History Society, in chalk- 

 fields near Bottom Farm, a few miles west of Henley-on-Thames. — 

 G. L. Bruce. 



New Yorkshire Hepatics. — On May 4, 1901, on Coatham 

 Marshes, North-east Yorkshire, I found a large patch of Morckia 

 hihemica covered with capsules, and in such fine condition that 

 Mr. Pearson says he has seen no specimens like it. From a 

 distance the patch had the appearance of Pellia epiphi/lla with 

 its long and crowded silvery seise. On washing out the ' Mordda, 

 I found a few plants of Petalophyllim Kalfsii (Wils.) Gottsche, with 

 young fruit, and quite distinct from the Morckia by the fan-like 

 frond with lamella on the upper surface. It is interesting to add 

 these two hepatics from the east coast of Britain. Mr. Pearson 

 says the Petaloplujllum is one of the most important discoveries 

 amongst the HepaticaB of recent years. — Wm. Ingham. 



Cardamine impatiens in Middlesex. — The existing records for 

 this plant in Middlesex are old ones, and their correctness is doubted 

 by Trimen & Dyer in their Flora, and apparently in Topographical 

 Botamj. It still occurs in the county, and with every appearance 

 of being indigenous ; I found several plants in June last on the 

 bank of a stream in the Harrow district.— P. Whichelmore. 



The Plates of 'English Botany,' ed. hi. — Is it possible to 

 ascertain who drew the plates first published in the third edition of 

 English Botany? As is well known, fresh details were added to 

 some of the original plates, while in some instances fresh plates 

 were substituted for those of the earlier editions. Messrs. Bell & 

 Sons, who bought the book from Mr. Hardwicke's assignees, have 

 no information on the subject. It would be of interest to place the 

 information on record, and possibly some reader may be able to 

 supply it. — James Britten.

Agardh has just been published — the final supplement to his famous 



Species Genera et Ordines Algarum . This work was begun, as is 



well known, in 1848, and in 1880 the second part of vol. iii. 



appeared. Eighteen years later the third part was published,' 



coming as a surprise to phycologists, for many other papers had
