the bird, and although of a coral red in hue 
are not so bright as in hirundo. 
The wings are rather large and the three 
outer primaries are provided with tips. 
The tail is very long, the outer feathers 
upon each side being greatly lengthened, 
making a deep fork in the center. In this 
respect it resembles paradisea. The entire 
tail is pure white with the exception of the 
outer webs of the two outer feathers, which 
are washed with pale pearl blue. The cap 
is of a pure deep greenish black. The back 
and whole of the upper parts resemble that 
of hirundo being of a deep pearl blue. . The 
under parts are as the back blending into 
white at the chin and ending abruptly at 
the under tail coverts which are pure white. 
The size varies considerably in different 
individuals; the length being the most var- 
lable measurement, on accountof the diff- 
erent lengths of-the tail. However | give 
the average measurements from a dozen 
specimens from my own collection; and 
which will be as nearly correct as the great 
variation in length of the tail will allow. 
Length 16.00 inches; Extent 31.75 inches. 
Wing to.50 inches Tail 7.50 inches (short- 
est 5.50 inches; longest 9.50 inches) Bill 
1.30 inches. 
The range of this bird is very large;it, 
being tound along the coast of North Am- 
erica, Europe, Asia, Africa; at large. 
I think that the breeding range as given 
by most authorities, is rather constricted. 
From reliable notes, I find that the birds 
breed from the southern bounding line of 
the Middle States, northward. 
The eggs are very similar to those of the 
other terns, being very variable in size, 
shape, color and markings, although as a 
rule they are slightly smaller than eggs of 
the preceeding or following species.

THE ANHINGA IN LEON COUNTY

With this bird I have had a good deal to do, 
From Tallahassee distant about 34 miles, is a 
small cypress swamp, and in thisswamp the An- 
hingas breed abundantly. 
It was in 1894 that I first had the good for- 
tune to make the acquaintance of the Anhinga’s 
nest and eggs, Prior to this time, it was a bird, 
comparatively unknown to me, and then I knew 
it only by its local name; Water Turkey. 
On the 13th. of April 1895 a friend and my- 
self entered this swamp. The first nest con- 
tained four fresh eggs. The second nest in the 
sime tree witha Ward’s Heron nest, which con-

Upon climbing to my nest, I found by touch 
only, that it contained what I supposed to be 
eggs of the Wood Ibis. but to my disappoint- 
ment they turned out to be simply Anhinga eggs.

We saw two nests which contained five young 
each, and one nest contained four young and 
one spoiled egg.

The close relation existing between physiolog- 
ical and pathological processes is shown in an 
interesting manner by a study of the develope- 
ment and fall of the antlers of deer when com- 
pared with changes which occur in bone as a 
result of injnry.
