I22 THE NORTHERN MICROSCOPIST. 
every letter was perfectly sharp and legible as the original printing, 
under a high magnifying power. Another specimen contained the 
written name and address of the Chairman, along with the date, in 
a small space the size of a hole punctured by a fine needle. Who 
is there of the present day who has not either seen or heard of 
Mr. Dancer’s micro-photographs ? 
PHOTO-MICROGRAPHS.—Our article upon this interesting subject 
seems to be producing fruit. At a recent meeting of the Man- 
chester Microscopical Society, Mr. Blackburn called attention to a 
collection of very beautifully-executed photo-micrographs by Messrs. 
Baum and Johnson of this city. They represented several depart- 
ments of microscopical study. Amongst them may be mentioned 
sections of the eye of the Death’s-head moth, showing the occelli and 
the branches of the optic nerve on a large scale ; also some beautiful 
diatoms, especially Moller’s ‘‘ Typen-platte” of 400 species on one 
slide; a symmetrically-arranged group of Triceratia; and Fleuro- 
sigma formosum with a portion of one of the frustules taken with a 
is immersion objective in combination with an F eyepiece. 
Since that date, Mr. Johnson has sent us some of the above, 
and in addition, Zrichina spiralis in situ, proboscis of house-fly, 
fulex felis male and female, Pulex trritans, diseased human lung, 
and the sheep tick JJe/ophagus ovis, all of which are admirably 
taken and form valuable contributions in aid of microscopical study. 
We have also heard that the art is being practised in Birmingham, 
but have no direct knowledge of it. 
LEAF FUNGI IN May.—When the student of Microscopy has an 
opportunity of getting a view of the hedge rows and green fields 
in. this, usually, delightful month, he should give a careful look out 
for leaf fungi, for they now may be found in tolerable plenty. Two 
of the many which grow upon the common wood anemone, ‘ Ane- 
mone nemorosa’ may be found in great plenty in various parts of 
the Bollen Valley from Hale to Wilmslow, and also about Marple 
and elsewhere. The commonest is a black smut, Puccinia ane- 
mone, which spots the leaf over with interesting regularity: the 
other is also a black smut, but this is in irregular patches, which 
burst through the leaf, and is known as Urocystis pompholygodes. 
Another interesting fungus may now be found upon the Gout 
weed, 4£gopodium podagraria. This Dr. Cooke speaks of as 
rare, and doubtless he is correct, for the plant is rare. Neverthe- 
less, the Gout weed is very plentiful all about Didsbury, Northen- 
den and Gatley. The green lanes leading from Didsbury towards 
Northenden are full of the plant. The fungus is a black smut 
which bursts through the cuticle of the leaf in patches: it often is 
found upon the stalk of the plant. 
The season being late, the cluster cup and smut on the Pile-wort
