Gives an account of the “mineral resin” described by Silliman in 187!). Gives analysis

Gives a list of the species in the 38th century of this exsiccata and reprints a note on 3704, 
TJrocystis hypoxidis Tliaxtcr, from Brazil, and the descriptions of the following new species:

This exsiccata after a long pause necessitated by the pressure of other work has been re¬ 
sumed and will be continued. In this article the names of the species in fasc. xxi, with 
synonomy and often with critical notes, are reprinted apparently as given on the labels. This 
fascicle includes Nos. 1001-1030 and 146b., 682b., 69b, c., 444b., 8b. The following new species 
are described: Pezizella dilutelloides on decayed petioles of Robinia pseudacacia near Berlin; 
Tryblidaria subtropica (Wint.) (= BUtrydium subtropicum Winter Hedw., 1885, p. 263); Cryp¬ 
todiscus pusillus (Lib.) (= Phacidium pus ilium Libert PI. arden, 268); PhyUachora lagcrheim- 
iana on living leaves of Ilex scopulus Panecillo, near Quito; Strickeria tingens Wagelin. in 
lift, on decorticated wood of Fraxinus, Switzerland; Meliola lagerheimii Gaillard on living 
leaves of Ilex scopulorum , Quito; Sphcerotheca gigantiascus (Sorok. et Tliiim.) Baumler 
(= Erysiphe gigantiascus Sorok. et Thiim. Mycotii. in Sched.) on Euphorbia palustris, T ress-

208-209. 
Gives a method of hastening the crystallization of trehalose by inserting in the solution 
a glass plate previously rubbed with a crystal of trehalose. The crystals collect about the 
portion of the glass thus prepared. Later they can be detached, and by scattering them 
crystallization will be provoked everywhere in the liquid. A footnote gives the method of 
first disposing of the mannite in the same solution. (E. A. S.)

Gives a method of observing the aerial parts of fungi by means of running over them a 
drop of collodion in solution and afterward transferring on the slide to glycerin jelly. By 
this means the fungus can be examined in its natural position. (E. A. S.)
