cesses, is the one most commonly found in cats; it is called 
Ascaris mystax, or the moustached worm, and may be expelled by 
the same remedy asrecommended for dogs. Since poor pussy has 
but few friends, I hope my readers will adopt the harmless and 
effectual remedy of 1gr. of santonine when a cat, apparently well 
fed and cared for, persistently loses flesh, and shows those other 
symptoms which in the more favoured dog would give so much 
alarm to the owners.

NOTES IN REFERENCE TO STICKLEBACKS’ 
NESTS. 
By Tuomas Botton, F:R.M.S. 
HEN Mr. Wilkins read his paper before the Birmingham Natural 
History and Microscopical Society I made an appoint- 
ment with him to go in search of some Sticklebacks’ nests, and in 
due course brought home several, one of which was placed in an 
aquarium in the window of our room at Mason’s College. The 
male Stickleback was soon reconciled to his new quarters, and 
diligently fanned his restored nest, from which in due course we 
estimated that he hatched out a brood of at least 250, making quite 
a populous tribe for a small aquarium about 12 inches diameter. 
Watching the nest and the doings of the Stickleback furnished 
much amusement to the members of the Society and other visitors 
to the room, and the eggs and young fry were often examined under 
the microscope to elucidate their development. I am afraid, 
however, that he was not sufficiently fed, or possibly he may have 
resented the frequent interference with his large family, for before 
long he commenced a raid upon them, and sad to relate, swallowed 
them all up with the exception of one little one, which managed 
to secrete himself amongst the weed and algz from his unnatural 
father. Not long after—we don’t know why—he succumbed him- 
self, leaving the aquarium as a home for his single descendant, 
who afterwards thrived well under the care of the curator, who 
occasionally fed him, or provoked his pugnacious nature for the 
amusement of visitors. 
In the middle of April last, at a casual visit to the room, Mr. 
Wilkins at once noted that this little Stickleback had put on the 
soldierly colours of various bright hues, characteristic of the male 
Stickleback at the time of maturity, and a closer inspection of the 
aquarium revealed amongst the weeds a fully formed nest, elaborately
