in the Zodlogischer Anzeiger (1882), translated in the Journal of the 
Royal Microscopical Society for February. This paper is on the 
mouth-organs of sucking insects. After describing the mode of 
taking food in the bees and bugs, which we refer to at another place, 
he deals at greater length with the Diptera. He dissents from 
Dimmock’s and Meinert’s view, that the labium of these flies is 
made up of the labium proper and the epipharynx, but considers 
e paired organs described by Meinert in Hippobosca, &c., as an 
independently formed epipharynx, to be enormous developments 
of the cheeks. The tactile hairs of the labella are connected with 
nerves, and organs of taste are situated on the labella or fleshy 
“tongue.” He confirms the opinions of previous observers as to 
the pumping arrangements of the salivary glands and the sucking 
apparatus of the pharynx. 
Martin anD Moate’s How ro Dissscr A Brrp..—A handy 
little volume is this, the second part of Messrs. H. N. Martin and 
W. A. Moale’s “ Hand-book of Vertebrate Dissection.” To begin 
by finding fault, almost the only fault that there is to find,and one 
that is doubtless caused by the low price at which the book is 
issued—the illustrations are too few and too rudimentary. 
The pigeon is taken as a type, and has the advantage of being 
readily accessible to all. The work begins by giving the zoologi- 
cal characters of the division, class and sub-order. Those of the 
order are omitted, and the character “sternum provided with a 
keel,” is rather that of the order Carinate than that of its sub- 
order, Schizognathz. The external characters of head, trunk, 
limbs, feathers and skin are first described, and the student is next 
directed how to prepare and examine the skeleton. This is fol- 
-lowed by the dissection of the soft parts, the neck, pleuro-peri- 
toneal cavity, veins and arteries, vocal, abdominal and reproduc- 
tive organs, brain and cranial nerves, eye and ear. Clear and con- 
cise directions are everywhere given, enabling any student of or- 
dinary dexterity and application not only to dissect a pigeon, but, 
better still, to dissect some other carinate bird, and note carefully 
Points of distinction between it and the pigeon.
