were about equally divided, and that the males were the 
smaller of the two, having also a distinct coil in the anal 
extremity. 
A preparation was here shown, belonging to the museum 
of the “ College of Physicians and Surgeons,” labelled 
“ A dog’s heart filled with worms, from Hong Kong, China.” 
The two specimens appear quite similar. 
Dr. Isaacs remarked that, a number of years ago, while in 
the city of Baltimore, he examined the heart of a dog which 
died from the effects of an operation for the removal of the 
spleen, and in that case the heart was filled with apparently 
the same species of worm. Dr. Isaacs also added that, in his 
case, the animal had previously exhibited symptoms of 
disease. He was short-breathed, and considered asthmatic. 
Here, too, the parasites occupied only the right side of the 
organ . — New York Journal of Medicine. 
THE NEW METAL. 
Aluminium begins, it appears, to come into more 
general use, at least in France. The eagles which 
surmount the colours of the army, hitherto made of 
copper, gilt by galvanism, are now made in aluminium, thus 
lightening the weight of the flag by nearly 2flb. Aluminium 
is more sonorous than bronze, and is consequently brought 
into use for musical instruments. Spoons and forks, drinking 
cups, &c., have also been formed of it. The weight of the 
new metal is about one fourth that of silver. Fine silver 
being worth 225f. the kilogramme, and aluminium 300f., a 
piece of the latter, equal in size to a kilogramme of silver, 
will only be worth 75f., instead of 225f. Thus an article 
which in silver would cost 50f. would be only l6f. in 
aluminium. 
NEW MANUFACTURES OF BEETROOT. 
A new alimentary production has just been invented, made 
from beetroot. It very closely resembles coffee, and has 
received the name of betterave tonrefliee. When mixed in equal 
proportions with West India coffee, the taste is by some 
persons thought more agreeable than that of the genuine 
article ; it is less heating, and does not require above half 
the quantity of sugar. Another new species of manufacture 
has just been created in France — the fabrication of paste- 
board from the pulp of beetroot. This fabrication is carried 
on to some extent in the commune of Foulain (Haute-Marne),
