PROGRESS OF MICROSCOPICAL SCIENCE. 
the production of ordinary lateral branches, or occasionally, in addi- 
tion to this, of a terminal spore-forming cell. Quite different is the 
germination of the spores, where an apical cell — the mother-cell of 
the cauloid part — is formed, and also the basal rliizoid cell, which is 
shut off by a transverse partition. The cauloid part grows by re- 
peated division of the terminal cell, the intercalated cells not dividing 
(except very occasionally) but reproducing by branching or spore- 
formation, while the terminal cell rarely develops branches or spores. 
Peculiar appearances of the Blood. — The ‘ Medical Record,’ in a 
recent issue, states that at the meeting of the Medical Society of Berlin, 
Dr. M. Litten described the appearances found in the blood of an 
ansemic emaciated man, aged twenty, who had suffered from enlarged 
masses of abdominal glands, reaching on each side of the spine from 
the diaphragm to below the promontory of the sacrum. Microscopic 
examination detected a diminution of the red corpuscles, which did not 
form rouleaux. The white corpuscles were large, and had a hyaline 
outline, which sent processes into the interior ; they contained granules 
and nuclei. These appearances remained constant for a long time. 
The abdominal and pulmonary symptoms increased, and a considerable 
excretion of indican took place, as a result of irritation of the peri- 
toneum. Five days before death oedema of the lung set in, rendering 
venesection necessary. On examining with the microscope the last 
drops of blood which flowed, a remarkable appearance was found. 
Very small red molecules were seen, which exhibited active move- 
ments ; no appearance of processes could be detected. Among these 
were found red corpuscles of ordinary form and size, and some large 
disks. On examining the blood an hour later it was found to be 
normal ; and it remained so until death. There was nothing remark- 
able in the marrow of the bones ; but the femur contained a reddish- 
brown gelatinous mass, such as is often seen in anaemic conditions ; 
there was red atrophy of the liver. Dr. Litten first thought that the 
appearance of the blood was due to ante mortem destruction. But 
against this there was the fact that the blood regained its normal 
appearance six days before death. Max Schultze has described 
a breaking up of the corpuscles at a temperature of 52 cent. 
(125 * 6 Fahr.); but this temperature is not reached in the human 
body. Similar appearances are observed in pernicious anaemia ; and 
microcytes are found in diseases attended with subcutaneous extrava- 
sation, such as scurvy. Hayem has found them in chronic anaemia, 
but not in such a marked form as in the present case. 
Origin of Lymphatics in Muscular Tissue. — We believe the first 
memoir on human histology that has been ever presented by a lady to 
the' Royal Society is that by Mrs. F. E. Hoggan, M.D., in the ‘ Pro- 
ceedings,’ No. 178. It is really Mrs. and Dr. Hoggan’s paper, and is 
entitled “ Lymphatics and their Origin in Muscular Tissues.” The 
authors announce that they have discovered the long-looked-for 
lymphatics of striated muscle, and describe them as radicles, valveless 
reservoir's, and valved efferent vessels. While describing their struc- 
ture and relations, they point out that the reservoirs are found on one
