favosa, tarsi, and versicolor ; also in the disease called acne) ; 
9, The nail fungus (referred to Aspergillus, Achorion, and 
Microsporon, by different authors); 10, Mucor (Mucedo) ; 
11, Aspergillus (several kinds) ; 12, Poenicillium (glaucum) ; 
18, Chionyphe Cariert (Berkeley ; the fungus which causes 
podelcoma in India). 
B. Enrorpnyres.—l, Torula (Cryptococcus Cerevisie; 2,- 
Sarcina (Merismopedia ventriculi) ; 3, Oideum albicans (in 
thrush and diphtheria in the mouth); 4, Leptothrix buccalis 
(including some found on other mucous surfaces besides that 
of the mouth); 5, Leptomitus (probably one species, but 
described as several, viz., L. wrophilus, Hannoveri, uteri, oculi, 
and one unnamed); 6, Bennett’s lung fungus (probably O1- 
deum) ; 7, Cholera fungi of Busk and others (perhaps Torula ; 
many were foreign bodies); 8, Lowe’s fungus of diabetic 
urine (an early condition of Aspergillus). 
To this list may be added Dr. Farre’s Oscillatoria, found in 
the intestines, of which an account is to be seen at the end 
of Dr. Lankester’s translation of Kiichenmeister’s manual, 
the paper having been read before the Microscopical Society 
in 1842. It was probably introduced into the body with 
drinking-water, but has as good a claim to be recorded as 
many in the above list, especially since Sarcina is considered 
by some as the spores of an Oscillatoria. If one is to be 
guided merely by the position of the fungi on the body, it 
is not evident why, in the list just given, Mucor and Peeni- 
cilium are to be reckoned amongst Epiphytes, whilst Ben- 
nett’s lung fungus and Leptomitus urophilus, though growing 
in similar situations, are considered Entophytes, 
A consideration which we consider of importance does not 
appear to be so regarded by Dr. Fox—the essential distine- 
tion, that is, between true and false parasites. In the second 
part of the treatise before us, Dr. Fox, speaking of the differ- 
ence between Epiphytes and Entophytes generally allowed to 
exist, says (p. 149)—“I confess I do not comprehend the 
distinction here pointed out; in either case the fungi require 
each its own particular soil for growth, which latter takes 
place in consequence of the implantation of the germs upon 
a suitable habitat ; and the properties aud tendencies of the 
vegetations are the same in the two cases.” Now, the dis- 
tinction of Epiphytes and Entophytes is pretty nearly that of 
true and false parasites; Tricophyton ulcerum and Puccinia only 
among the former being false, and O7dium albicans, and pos- 
sibly Sarcina, among the latter, true parasites; so that the 
above quotation may be considered as expressing the author’s
