588 DISEASE IN WILD MAMMALS AND BIRDS 
segmentation of rather unifoi-mly long bacilliform shape. Metachro- 
matic bodies not so distinct but seem larger where found. Coarser 
threads have swellings in some of the areas which are not segmented and 
this type seems to have more branching and metachromatic bodies; in 
other words it would seem that this is a form that reproduces by budding 
or intercalary spore formation. 
Forty-eight hours. — Much the same, more long threads with trans- 
verse division, somewhat more delicate, generally fewer coarse threads 
with swellings and spores. Still pale purple and not distinctly Gram- 
positive. 
Three days. — Condition much the same. 
Four days. — Two forms present — definitely Gram-negative delicate 
slender threads, nearly Gram-positive, and heavier, curved and twisted 
long bacillary forms, some streptococcoid threads and a few bulbous 
short threads. Very few metachromatic bodies. 
Five days. — Condition much the same except that the delicate 
threads are inconspicuous and the darker purple bacilli have increased. 
Metachromatic bodies increased as have swellings in coarser threads. 
Six days. — Much the same but for the appearance of young, deli- 
cate definitely Gram-negative threads. There are fewer metachromatic 
bodies and internal spores. 
Seven days. — The same. 
B. — Grown on Loeffler's blood serum. — Loeffler's stain. 
Twenty-four hours. — Delicate, poorly stained short threads, few 
tiny metachromatic bodies. 
Two days. — Not well stained, relatively short threads show numer- 
ous metachromatic bodies varying from exceedingly tiny dots to coarse 
granules wider than the thread. These may be numerous in the same 
segment and form a row from six to ten. Many short bacillary forms. 
Three days. — Poorly stained, metachromatic bodies apparently more 
numerous but much smaller. 
Four days. — Almost entirely short, heavy bacillary forms, some 
of which are very like diphtheria bacillus in the irregularity of width; 
many metachromatic bodies, distinct branching, some of the small 
heavy ones have fusiform swellings ; practically no long, heavy threads. 
Five days. — Essentially the same, individual elements slightly larger, 
fewer but coarser metachromatic bodies, more numerous round forms 
suggesting large pale cocci. 
Six days. — Much the same but elements shorter, smaller and some 
more segmented. 
Seven days. — More long forms of uniform staining but still a 
majority of coccoid or short bacillary forms with irregular staining 
and metachromatic bodies; no long threads. 
B. — Gram's stain. 
Twenty-four hours. — Pale purple, almost Gram-negative, long, slen- 
der but well outlined threads, a few coccoid forms, practically no 
granules.
