128 THE MICROSCOPE. Sept 
racemosus, Fres, ¢This grows exactly like the Penicillium 
as far as its vegetative part, the mycelium, is concerned. 
It is whiter and more fluffy, however, when grown on 
artificial media, and in 36 to 48 hours sends up its fertile 
branches. These are erect, non-divided, and bear at. the 
apex a round smooth head 50 microns in diameter. In 
this head there are hosts of spores, which are spherical 
smooth, light to fawn color, 4 to 6 microns in diameter. 
In Petri dishes these heads are borne on branches some- 
times lcm. high. The fertile branches also have short 
side branches. This is one of the characteristic features 
of this mucor. At maturity the whole plant is tawny- 
white in color; the spore case breaks, but does not dis- 
appear or deliquesce as it does in many similar species. 
In most media the formation of swollen cells on the 
mycellium is to be noted; these are the ‘“chlamydo 
spores,’ more or less characteristic of this species. 
This plant produces a great deal of havoe in all solu- 
tions containing sugars or glucosides, and even in alka- 
loid solutions. It ferments the sugars and glucosides, 
and if there is anything organic other than the alkaloid 
to break up it seems to attack it, and thereby destroy 
the alkaloid. Solutions of morphine and cocaine inocula- 
ted with this organism failed to give the characteristic 
color reaction after three weeks. Further investigation 
along this line is in progress in the laboratory.-Drug Cir. 
The use of the Thyroid Gland in Medicine is of special 
and peculiar interest because, instead of haying been 
deduced empirically like most other features in medical 
practice, it has been adopted as a logical conclusion from 
adequate premises.
