Bats. They will all be adults if you get them at this season. N.B. 



Any Bat over 12 inches will be new to Ireland Look for 



V. Daubentonii in any holes in bridges, or flying over the water. Any 

 Bats from hollow trees are worth attention.

(April 26th.} The small crucifer was a Cochlearia of some kind, 

 I think C. officinalis ; and this leads me to ask you to look carefully for 

 C. anglica along the salt-water muddy creeks in Wexford. It is taller 

 than officinalis, and its root-leaves are longer, oblong, not cordate, at 

 base. But the ripe fruit is the best character. In officinalis it is round, 

 and the dividing dissepiments round also. In Cochlearia anglica the 

 fruit is larger, and oblong, with a long dissepiment, with the fruit 

 swelling beyond it on each side. Please ask your friends kindly 

 to send me some stems with ripe, full-formed fruit, and a root -leaf or 

 two, and to search earnestly for this very rare Irish plant. In fact, I 

 have only seen one Irish specimen which seemed to be C. anglica. . . . 

 In re Bats, could not you get a few specimens, while in England, of the 

 rarer kinds, especially the Noctule, the Great Horse-shoe, the Serotine? 

 .... I suppose you have some bird-stuffer in Harrow who could skin 

 them. 



(May i^th.} I am ashamed to have two of your letters to answer. 

 .... I think the Cochlearia, small as it is, is C. anglica. Another 

 which Miss Glascott sent me I should certainly refer to C. anglica; 

 but I hope Miss G. will send some seed-vessels before long. It is a 

 mistake to dry specimens so early in the season, because all ought to 

 have the fully-formed fruit. For instance, the Carices especially require 

 to be in fruit, and all those you have sent to-day are too young ..... 

 By-the-way, have you any naturalists' club in the school ? There are 

 a good many plants to be found round Harrow ..... And are you 

 collecting the Land Shells ? These are easily carried, and take up
