part, almost oily in appearance, which does not stain. The author gives 
some details as to his observations, and remarks that, as to the origin of 
these nucleoli, no one has been able to give a definite account of how 
they became connected. 
Lymphatic Glands of Nereids.* — Prof. A. Ko wale vsky demonstrated 
both by sections and by injections of carmine, &c. that a pair of lymphatic 
or phagocytic glands occur regularly in each segment (of Nereis cultri - 
fera and other forms) just above the parapodia. He responds to Mr. E 
J. Goodrich, who regarded the alleged organs as accidental agglomera- 
tions of leucocytes. 
Earthworms from Celebes.f — Dr. W. B. Benham remarks that, al- 
though a considerable number of species of Perichseta have been de- 
scribed from the Malay Archipelago, none seem to have been collected 
on the island of Celebes or from Jampea, which is due south of it. Mr. 
H. Everett made a collection of twelve worms, which fall at least into 
six groups, none of which agree with any species hitherto known. We 
are glad to add that Dr. Benham has appended to his description of the 
anatomy of the individual a summary of what he regards as the charac- 
teristic features in the form of a diagnosis. He, like others, has much 
felt the absence of such a brief resume in many instances, while reading 
through the literature of the genus.

Filaria nocturna.j — Mr. F. Henry reports an interesting case of 
indigenous parasitic cbyluria with Filaria nocturna in the blood. This 
is the first case that has been observed in Philadelphia, and was intro- 
duced from the south. The patient; came under treatment to be 
delivered of a child, who was born healthy. Before delivery, she had 
complained of pains in the region of the kidneys. The urine was milky, 
and contains signs of albumen, but no sugar. On microscopic examina- 
tion of the blood, the author discovered in it Filaria sanguinis. At first 
about five Filarise could be seen in the preparation, but later on they 
were more numerous. They were only found in the blood at night. 
The author made use of several leeches to see whether they would serve 
as intermediate hosts. 
The parasite only lived for three or four days in the leech and then 
died. In the course of six weeks the blood and the urine were repeatedly 
examined, and during this time Filaria nocturna was always found in the 
blood, and often in the urine. The parasite was not killed either by 
treatment with chinin, thymol, or metbylen-blue. The use of the last 
reagent caused colouring of the blood-serum, and of the parasite itself, 
while the stools and urine of the patient were coloured, as were also 
the stools of the child whom the patient suckled. 
According to the author’s observations, Filaria nocturna rebelled 
against all medicines that were tried. The parasite appears also to 
have a great power of withstanding cold. It lives for ten days in
