POPULAR SCIENCE REVIEW. 
the whole cell gradually squeezed itself through the capillary wall (the part 
within the vessel becoming greatly attenuated and elongated) until it also was 
carried away. In the former case, the cell, shorn of part of its substance, still 
remained outside the vessel ; in the latter, it of course disappeared entirely. 
As regards the time occupied in these phenomena, Dr. Saviotti finds that 
the cell processes penetrate the vessels in a period varying from three to six 
hours, and that it takes about the same length of time for the whole cell to 
follow and to be washed away from the internal surface, to which it long 
remains adherent. 
Increase in Temperature of the Pulse. — Dr. Rattray has contributed a very 
valuable paper on this important subject to the Proceedings of the Royal 
Society , from which we take the following : — 
Temperate climate 
(near England), 
Tropics generally, 
Equator, 
temp. 84° F., 
average of 7 days. 
June, temp. 65° F., 
average of 10 days.

"While observation thus showed that the average temperature of the body 
about the latitude of England is 91-3° F., the following Table shows that 
it rises in the tropics to 98£-99-99£, and occasionally even to 100° F. This 
fact is interesting, if not important, in connection with temperatures in 
disease ; and the mutual relation of the two is worth study. 
Hair Tonics, Washes, and Cosmetics . — It is of importance that the scientific 
world should not allow the immense trade in these articles to pass by alto- 
gether unnoticed. It would be neither well nor wise that it should be so. 
We are therefore glad to see that Professor C. F. Chandler has given 
some very interesting details in his Report to the New York Board of 
Health concerning the above. The following is a brief account of this 
gentleman’s researches : — Ilair tonics, washes, and restoratives ; lotions for 
the skin ; enamels ; white powders for the skin. Of the substances named 
in the first category, sixteen were examined, all of which, with but one 
exception, were found to contain lead, generally in the form of the acetate 
or sugar of lead. No 11 among these samples is Mrs. S. A. Allen’s Cl world's 
hair restorer,” of 198 and 200 Greenwich Street, New York. One fluid 
ounce of this cosmetic (largely advertised) contains— Lead in solution, 5 20 
grains ; lead in sediment, 0 31 grain — total, 5*57 grains. The one sample 
free from lead was an ammoniacal solution of nitrate of silver, containing 
4*78 grains of the nitrate in 1 fluid ounce. Of the lotions for the skin (six 
different samples were analysed), only one was made up with injurious 
metals, viz. an American compound known as u Perry’s moth and freckle 
lotion/’ containing, to the fluid ounce — Corrosive sublimate, 3*61 grains; 
and crystallised sulphate of zinc, 4 25 grains. Among the enamels for 
the skin, seven different samples were tested, among which three contain- 
ing from 108 94 to 190 99 grains of white lead in 1 fluid ounce; other
