the "Scrub Tick.'' Museums throughout the colonies 

 cannot give any reliable information respecting ticks, nor 

 have they even a representative collection of the known 

 species which are commonly met with. Consequently there 

 is a vast unexplored field of research in this direction. 



Laboratory. — In San Francisco is a Bacteriological labo- 

 ratory which makes examinations of water, milk, blood, 

 urine, sputum, pus, diphtheretic membrane, and tumors. 

 It gives instruction to pupils and supplies curative mate- 

 rials. Dr. George L. Helms has charge of microscopy 

 and histology. 



BIOLOGICAL NOTES. 



Nasal Tissue. — Dr. J. Wright has studied the nasal 

 tissue of the bull and finds it erectile and much larger than 

 in the ox or cow. Selecting the thickest portion of the 

 tissue in case of a bull for comparison with that of the 

 castrated animal, he hardened, embedded in celloidin and 

 made sections perpendicular to the surface. The sections 

 were stained and photographed. There is very great dif- 

 ference shown thereby as may be seen in the New York 

 Medical Journal for Nov. 19, 1898. 



MICROSCOPICAL SOCIETIES.

N.Y. Society. — The New York Microscopical Society has a

 ary). It was incorporated in 1877 and holds an annual 

 meeting on the first Friday in January. Its semi-monthly 

 meetings are held on the first and third Friday evenings
