FinELY GrounD Gtass,—For the preparation of drawings for 
the lantern by Mr. Dallinger’s method, a very finely ground glass 
is necessary. ‘This is often difficult to procure, but many of our 
readers will be glad to know that it may be obtained from Messrs. 
Leather, Sadler, and Holmes, 38, Dantzic Street, Manchester. 
MOUNTING THE PROBOSCIS OF THE FLy.—In our next issue we 
hope to give a detailed description of ‘ How to do it,” by Mr. W. 
Chaffers, who very successfully demonstrated the process before 
the members of the Mounting Class of the Manchester Micros- 
copical Society at its last meeting. 
Drawincs oF Livinc OrGANIsMs.—We have received No. 8 
of Mr. Bolton’s “ Portfolio,” which is published at the price 
of One Shilling. The Vegetable Kingdom is illustrated by Pra- 
stola crispa, Rivularia angulosa, Vaucheria, Cosmarium botrytts, 
various fresh water diatoms, and the frog-bit Hydrocharis Morsus- 
Rane. The Animal Kingdom by Loxophyllum meleagris, Condy- 
lostoma patens, Vorticellidee, Zoothamnium arbuscula, Stentor niger, 
Qeistes crystallinus, Floscularia campanulata, F. trifolium, Limnias 
annulatus, Piscicolo geometrica, Planaria lactea, and the fry of the 
Mussel (Afytilus edulis). We are glad to note that the several 
drawings and descriptions are much more uniform than formerly, 
and this is important to those who wish .to bind them into 
volumes. 
Mr. Corr’s Stupres.—Number 24 of this series gives us a very 
minute description of the Pillwort—/i/ularia globulifera. The 
minute structure of the stem, the general arrangements of parts, 
the microscopical appearances of transverse sections, and of 
longitudinal sections are all ably described in this number, and 
continued in No. 26, which latter also contains some admirable 
chromo-lithographs of the Dolerite from Dalmahoy Hill. No. 
25 is devoted to the human thyroid gland, containing a general 
description with methods of preparation, and the bibliography of 
the organ. No. 27 contains drawing and description of thymus 
gland of calf; while No. 28 is devoted to le and is well- 
worthy of perusal, 
Mr. Cole announces that No. 29 will contain a T. S. ‘of the 
Human Pancreas, stained carmine, with an illustration magnified 
333 diameters, with accompanying letterpress. No. 30 will con- 
tain a large plate of chalk drawings in black, illustrative of the 
different forms of Lichens, and their structure. The letterpress 
will contain a digest of the development of Schwendener’s theory. 
The accompanying preparation will be a T. S. of the Thallus of the 
rare species Sticta aurata.
