muscles of the lower part of the neck, and the * measle' 

 removed by Mr. Heisch ' from the centre of a mutton chop' 

 (' Entozoa,' he. cit., p. 30), are clearly referable to one and 

 the same form of armed cestode larva. Setting aside the 

 errors of interpretation above-mentioned, Dr. Maddox's con- 

 tribution is most interesting, not only as confirming the 

 experiences of three separate English observers (as to the 

 fact of the occurrence of measles in mutton), but as adding 

 numerous and useful microscopic details. 



Lostorfer's SypMlis-corpuscles.i — The observations of Los- 

 torfer who described certain bodies which he affirmed becan?e 

 developed in the blood of syphilitic persons have been very 

 generally discredited. 



Lately, however, Biesiadecki ( Untersuchungen aus clem 

 Pathologisch-Anatomischen Institute i?i Krakau. Vienna, 

 1872), following Lostorfer in a large series of experiments, 

 has come to the conclusion that the assertions of Lostorfer 

 are, with some slight modifications, correct. The mode in 

 which Biesiadecki proceeds in his observations is similar to 

 that employed by Lostorfer. By means of a pointed needle, 

 a small drop of blood is taken from the perfectly clean finger, 

 brought on a clean glass slide, and covered with a glass. By 

 a slight pressure on one edge of the cover-glass with the nail 

 of the finger, the blood can easily be made to spread out so 

 that the blood-corpuscles lie only in one layer, without being 

 broken up and destroyed. Preparations in which the blood- 

 corpuscles have not spread out into one layer, or in which 

 they appear to be squeezed, are to be put aside as useless. 



A number of preparations are brought into a moist chamber, 

 where they are kept at a temperature of 14 — 18° C. (57 — 

 64° Fahr.). ... 



In most of the preparations which have not become dry 

 at the edges of the cover-glass, taken either from syphilitic 

 or other patients, e.g. arthritic or rheumatic, there appear on 

 the second, third, or fourth day numerous needle-shaped or 

 rhombic haemoglobin-crystals, varying in diameter from that 

 of a blood-disc to twice or three times as large. In blood- 

 preparations of syphilitic patients the following changes take 

 place, beginning from the fourth day. In the yellowish 

 coloured plasma there appears a cloudy opacity, which is due 

 to the presence of small flakes. These latter are seen to 

 contain extremely small spherical bright granules, which 

 generally possess a filamentous appendix. The fifth day the 

 number of these granules becomes much greater ; they become
