4 ALTERATION OF POSITION,

DISPLACEMENT. 
Rea or apparent displacement of organs from their 
usual position is an almost necessary consequence of, 
or is, at least, coexistent with a large number of tera- 
tological phenomena. It is obvious that abnormal 
unions or disunions, suppressions, hypertrophies, &., 
are very liable to bring about or to be accompanied 
with changes in the position, either of the parts 
directly affected or of adjoining organs. 
In this place, then, it is merely necessary to allude 
to some of the more important displacements, and to 
refer for further details to the sections relating to those 
irregularities of growth on which the displacement 
depends. 
Displacement of bulbs—I owe to the kindness of Mr. 
James Salter a tulip bulb which had been dug up after 
flowering, and from the base of which were suspended 
several small bulbs; and I have smce seen another 
specimen showing the same unusual arrangement. The 
explanation of these formations seems to be that they 
correspond to the bulbils ordinarily found in the axils 
of the seales of the parent organ, and which, m some 
way or another, have been displaced and thrust into the 
ground. Professor de Vriese figures something of the 
same kind in [via carminosa.' 
Of somewhat different nature to those above described 
was an anomaly described by M. Gay at a meeting 
of the Botanical Society of France, April 8th, 1859. 
The plant affected was Leucoium cstivum, and the 
changes observed were apparently attributable to a 
simple separation of two leaves that are usually con- 
tiguous. “Suppose,” says M. Gay in describing this
