experiments were made upon only a few grains of each. 

 The specimen of gadolinite employed weighed several 

 ounces, and enabled us to procure such quantites, both of 

 yttria and oxide of cerium, that we were enabled to repeat 

 our experiments till we satisfied ourselves of their near 

 approach to accuracy. The preceding account contains the 

 most material facts which we ascertained. The experiments 

 themselves occupied several months, and would have occu- 

 pied a great deal of room had Ave thought it requisite to 

 detail them at full length.

Examination of Lymph, Blood, and Chyle. By John Muller, 

 M.D. Professor of Physiology in the University of Bonn. 

 (Poggendorff's Annalen, Band xxv. 513.) 



In the winter of 1831-32, a favourable opportunity occurred 

 at Bonn for examining human lymph. Professor Wutzer 

 had a young man under his care with a wound of some 

 standing on the upper part of the foot. When pressure was 

 made on the back of the great toe, in the direction of the 

 wound, a clear liquid spouted out, which was lymph. In 

 the course of 10 minutes it deposited a cobweblike coagulum 

 of nbrine. According to Reuss, Emmert, Sbmmering, and 

 other late observers, the lymph contains no globules. 

 Hewson, however, in the lymph from the thymus gland of 

 the calf, discovered numerous white globules, and in the 

 reddish lymph of the spleen, red globules. Dr. Nasse and 

 Hrn Muller, by means of the microscope, appear to have 

 established the same fact in reference to human lymph. In 

 clear, transparent lymph, they observed a number of colour- 

 less globules, which seem smaller and less abundant than 

 the globules of human blood. Part of these globules is 

 included in the coagulum, but the greatest portion remains 

 suspended in the serum of the lymph. It is to be remarked 

 that the coagulum is not formed by the accumulation of the 

 globules, but it may be easily perceived that a substance 

 previously in solution coagulates, and takes up part of the 

 globules. These globules may be more distinctly seen in 

 the coagulum, when a small portion of the lymph is placed
