Finally, it has suggested that in addition to these agencies, all leucocytes and, under certain circumstances, the plasma, contain a protective agency, trypsin, which, with Metchnikoff's phagocytic cells, serves to destroy micro-organisms and convert their toxins and other albuminoid poisons into harmless products. Considered jointly, these various factors seem to us to represent the aggregate of vita phenomena.
Page 2381 - ... until the mixture, losing its blue color, becomes purple in color and a scum with yellowish metallic luster forms on the surface, while, on close inspection, a fine-granular black percipitate appears in suspension. (This requires about 500 cc of the eosin solution for 100 cc of the alkaline methylen blue solution.) This precipitate is collected on a filter and without washing is allowed to dry.

Page 2536 - In pathological urines other than those containing sugar and albumin, the same tendency to maintain a constant proportion between the freezing point and specific gravity may be observed, although within rather wider limits than in the case of normal urine.
Page 2491 - Collect carefully ; spread upon the surface of a smooth fragment of porous soapstone ; place the stone in a saucer, the bottom being covered with water ; invert a tumbler over it, and the spores will grow well. Or place in the moist chamber given in the JOURNAL. Some prothallia advance beyond the rest, produce antheridia and bear many archegonia. Now keep the crop with little moisture for several weeks, then suddenly water it and a great number of antheridia and archegonia simultaneously open, and...
Page 2367 - When the animal is completely extracted, the interior should be thoroughly washed out with the syringe. A small piece of sponge on the end of a fine copper wire, which can be bent in any direction, is very useful for removing the mucous, which is apt to adhere to the interior of the shell.
