T Aesonrnon or SOLID PARTICLES. — ‘t The Lancet” reviews th this 
interesting and timely subject. Oesterlen, nearly thirty years ago, 
found molecules of mercury in the blood of cats, absorbed from 
the stomach ; ` and he, Eberhard, Landerer, , and especially Yo Vo it k 
rubbed the same material into the skin of cats and dogs and fi md 
it in the liver, spleen, and other internal organs. The experimen 
of Herbst and Bruch seemed to demonstrate the absorption l

Moleschott fed frogs on blood-corpuscles and pigment-corpuscles 6 t 
sheep, and saw these’ corpuséles circulating in the web of the f 
foot ; while Donders and Mensonides found charcoal in thel 
of rabbits with whose food it had been mixed. Thus the absorption 
of solid particles through uninjured. membranes has become n 
certain notwithstanding the negative results obtained by Bares 
prung, Recklinghausen, and a few other experimenters. M. Hein- 
rich Auspitz has recently continued these researches by means ¢

small specific weight, and easily recognized by their form and 
the iodine color-test, vary from about the size of the red cor}

tissue, and subsequently recognized in the circulation..
