94 MESSRS. F. CURREY AND D. HANBURY ON SCLEROTIUM STIPITATUM, 
Waring, for the Museum of the Pharmaceutical Society. PL IX. fig. 4 represents a thin 
section of the white inner substance of the Sclerotium, taken from near the circumference. 
The threads are of very irregular shape, and hardly similar in any two sections ; but their 
general nature may be seen from the figure just referred to. 
2. 1? achy ma Cocos, Pries. The variety of names which this remarkable substance has 
received, renders a list of its synonyms not undesirable ; we therefore subjoin one which, 
with the needful references, will, we believe, be found nearly, if not quite, complete.

Pine specimens of this production, received many years since from Dr. Macbride of 
South Carolina, and described by him in the 12th volume of the * Linnean Transactions,' 
under the name of Lycoperdon solidum, are to be seen in the Museum of the Society ; 
and one of the most characteristic of these specimens is represented in PL X. fig. 5. 
PI. X. fig. 6 represents a longitudinal section of a very similar specimen, and is in- 
teresting as exhibiting very completely the manner in which the root has been affected 
by the Pachyma. Dr. Macbride states that the Pachyma originates between the wood 
and bark of living roots, that it gradually detaches the bark, while it spreads round the 
wood and converts it into a substance similar to itself. The present section, however, 
exhibits an intermediate condition ; for, although the bark is detached and the Pachyma 
interpolated between it and the wood, a great part of the wood itself is but little affected. 
The portion referred to by the letter a retains its natural colour and appearance ; and 
when examined in section under the microscope, is found to consist of healthy woody 
tissue in an almost perfect state. This portion, when looked at with a lens, or even with 
the naked eye, may be seen to be traversed by narrow longitudinal white streaks, which 
the microscope shows to be very similar in composition to the part marked b, next de- 
scribed. This part (b) to the naked eye looks like wood of a very pale colour, but it 
presents a totally different appearance under the microscope. It consists of what appears 
to be a mass of mycelium, the threads of which have forced their way through the sub- 
stance of the wood in every direction, separating the cells and converting them into irre- 
gularly shaped bodies of a highly refractive nature, having a good deal the appearance of
