portion of the uterus. These bodies could not be mistaken for epithelial 
cells owing to their size, for they were five to eight times as large as a 
red corpuscle. Those within the cells were smaller than those lying 
free. In shape they were spheroidal to oval. The nucleus was smaller 
and less easily stainable than that of the epithelial cells, and a nucleolus 
was not constant. In fresh preparations, movements of the Amoebae were 
observed. 
Trichomonas in Urine of Men.* — Herr F. Marchand gives a very 
complete description of a case of a man in the urine of whom Tricho- 
monads were found. The urine contained much albumen, and on standing 
a dirty yellowish purulent deposit was thrown down. In addition to 
epithelial and pus cells, &c., the Microscope showed the presence of 
peculiar hyaline bodies somewhat larger than leucocytes, and exhibiting 
movements. In size these varied from 0*012-0 *03 mm. in length and 
0 * 01-0 * 015 in breadth. The posterior end was rounded or terminated in 
a short straight tail-like prolongation. The anterior end was pointed or 
rounded, and the general shape of the animal was oval to round. Four 
flagella sprang from a common base at the anterior end. The protoplasm 
was homogeneous and hyaline, though sometimes it contained a number 
of small vacuoles. No contractile vesicle was observed. During life, 
when they exhibited amoeboid movements and alterations of shape with 
pseudopodial extensions, no nucleus was visible ; but on adding methy- 
len-blue solution this was brought out as a round or oval body lying 
near the base of the flagella. In some nuclei nucleoli were present. 
Similar results were obtained with osmic and acetic acids and with 
sublimate. 
The author then compares this organism with Tr. vaginalis , and 
shows that there is a close resemblance between the two. 
Dr. K. Miura f has also observed a similar case, though in this instance 
there was no albumen in the urine or disease of the pelvic viscera as in 
the foregoing. ' The urine was yellow and acid, with some flocculent 
deposit, which on examination showed among other things mobile 
Infusoria somewhat larger than pus corpuscles. These organisms were 
somewhat pyriform in shape, the posterior end having a tail-like pro- 
longation, near the base of which an expansion was occasionally present. 
At the anterior end were one, two, or three flagella. From the base of 
the flagella there extends down one side an undulating membrane which, 
from its constant movement, now appeared as if it were inside, now out- 
side the body. The animals were very mobile and altered their shape 
continually. The average length of the body was 0*017 mm., breadth 
0*012 mm. ; of the flagella 0*01 mm., and of the tail 0*006 mm. The 
author concluded from experiments that these animals inhabited the 
urethra and not the bladder. 
Parasite of Vaccinia and Variola, f — Dr. M. A. Buffer and Mr. H. G. 
Plimmer describe a parasitic protozoon which they have found in vaccinia 
pustules of man, cow, monkey, and rabbit. The parasite is a small round 
body, about four times the size of a staphylococcus. It usually lies in 
a vacuole in the cell plasma, and sometimes appears to have a more
