Back Xumbers of the Billetin. — Single odd Xos. wili be furnished 

 gratis to subscribers when needed to complete sets, but Xo. 2 is entirely 

 exJiaiisted. Will all those who have an extra copy of this Xo. kindly return 

 same to the Editor who then can accommodate others. Unfortunately only 

 a very few complete sets of Vol. 1 are left but the price will remain as before 

 noted, namely, 50 cents: for bound copies, 75 cents. 



AcKXOWLETXiEMENT. — We take pleasure in thanking Dr. Wm. Trelease 

 for the use of the beautiful cut of Lepiota on the last page ofthis^^o., 

 originally puljlisbed iu the Annual Report ot the Missouri Botanical Garden. 

 Another from the same source will follow. 



Descriptio\.s. — At the risk of seeming technical, suggestions and direc- 

 tions are given on the inside pages of this Xo. for critical study of 3Iit.<iJi rooms. 

 Really very many ought to lay hold of this matter seriously, ergo profitably, 

 — particularly teachers of Nature Study and of Botany. The two pages 

 will be reprinted on a single narrow leaf for convenience of the strenuous. 

 Additional suggestions to appear on page 81.
