Test incrusted with foreign particles. 



Pleurophrys compressa, Eilh. Schulze (fig. 9). 



Of this form the author had as yet found but a single ex- 

 ample (in a ditch at Rostock). Its length was 0-075, breadth 

 0-04 thickness, O'Ol mm. Elliptic compressed without neck, 

 mouth truncate; in side view test of lanceolate outline. 

 The author saw (notwithstanding the opacity caused by the 

 coating of siliceous arenaceous particles) the large round 

 nucleus shimmering through. The author found also Pleuro- 

 phrys fuha, mihi; of the correctness of his identification of 

 this form there can be no doubt. 



Pleurophys lageniformis, Eilh. Schulze^ (fig. 8), 



is a form found by the author in sea water ; its length 

 was 006, greatest breadth about 004 mm. It is elliptic, 

 drawn out into a neck, mouth truncate, in end view cir- 

 cular ; pseudopodia numerous ; the author did not perceive 

 a nucleus ; of its presence there can, however, really be no 

 doubt. 



0)1 the Lymphatics mid Parenchyma of the Thyroid 

 Gland of the Dog. By E. Cresswell Baber, M.B. 

 Lond. (With Plate XIV.) 



The following is a concise account of a research carried 

 out under the direction of Dr. Klein, and described at 

 length in a paper read before the Royal Society in January, 

 1876.'-' 



Previous Investigations on the Structure of the Thyroid 

 Gland. — The results of these may be gathered from the 

 writings of Henle,'' Kolliker,'* Verson,'^ and Frey.^ Accord- 

 ing to these authors the thyroid gland consists of numerous 

 vesicles embedded in, and supported by, a stroma or frame- 

 work of connective tissue, containing blood-vessels, nerves,

The stroma is directly continuous with the capsule of
