88 Selected Articles in Scientific Serials. [January, 1882. 



Boston Society of Natural History, Nov. 16. — Mr. Wil- 

 liam Trelease compared the glands of plants with those of ani- 

 mals. He described the histology and showed the homology of 

 the organs in question. The glands are anomalous in that a deep- 

 lying tissue secretes the fluid, which reaches the exterior through 

 a distinct break in the epidermis — not a stoma. The secreting 

 tissue is the end of a fibro-vascular bundle, the cambium having 

 produced the active cells, instead of wood cells, the whole being 

 surrounded by a thin bast sheath. He described a number of 

 cases showing the glands to represent undeveloped flowers, as 

 previously indicated by Delpino. Professor D. P. Penhallow then 

 read a paper on the temperature of trees. 



Dec. 7. — Professor A. Hyatt described the sponge found in the 

 Boston Water Supply, and Mr. B. H. Van Vleck discussed its 

 distribution in Farm Pond, and the general condition of the lat- 

 ter; Dr. Wm. F. Whitney showed a skull of an ancient Mexican, 

 with an arrow-head imbedded in the superior nasal fossa. 



American Geographical Society, New York, Nov. 25.— Dr. 

 I. I. Hayes 1 delivered a lecture on the water-ways of New York, 

 considered in relation to the transportation interests of the State, 

 and the commerce of the city.
