murky or lurid yellow, or brown tints, rapid move- 

 ment, connexion with heavy squalls, and highly- 

 charged rain-clouds. It is seen mostly in autumn and 

 winter. Locally termed pocky cloud and rainball. 

 (See article above mentioned, " Popular Science 

 Review," 1879.) The smooth, even outline of this 

 form of cloud is sometimes remarkable. 



III. Saw-Cloud. — This form is a composite one, 

 indicating a transitional state of the weather. It 

 is frequently attached to a bank of stratus, some- 



is form, because of the peculiar symmetry and of 



its illustrating the same condition of atmosphere as 



the foregoing form (Saw Cloud). It has the same 



general characteristics, but is seen in larger and 



rounder masses. t,

times assuming, however, a bead-like form, and 

 detached. 



It may then be called " Bead-Cloud," or " Double 

 Saw-Cloud." Attention is drawn specially to this 

 form on account of its being one of the best indicators 

 of a disturbed state of the atmosphere. In my ex- 

 perience it is highly electrical. In rainy summers 

 (e.g. 1879) ^ is generally an attendant on thunder- 

 storms. Characteristics — association with disturbed 

 and mixed forms of sky ; slaty, ashy, and dark tints ; 

 great opacity. This cloud should be compared with 

 the double, or "dropping cumulus," which assumes 

 the " bolster " form, and also with the following : viz. :

SOME REMARKS ON FUNGI. 

 By Haygarth Addison, L.R.C.P., &c. 



IT is strange that in an age like this, the Agaricus 

 campestris, or common mushroom, should be the 

 only — or nearly only — member of this class used as 

 food in this country by those who have but a slight 

 knowledge of fungology. 



We will consider first a few of the culinary fungi, 

 showing that " the " mushroom has not alone all the 

 glory to itself, of being regarded a tonne bonche. 



Probably the most famous of them all is the truffle, 

 which has been a luxury ever since the days of Pliny. 

 This fungus is found growing under trees and deep in
