tlie matter. Moreover, should it be ultimately demonstrated that the 

 processes by which the different carbohydrates are elaborated are 

 actually distinct from one another, we should still require a term for 

 the very general phenomena of starch production, and for this amylo- 

 synthesis " would be unobjectionable. 



In conclusion, it may be urged in favour of the terms proposed, that 

 they are clear and precise, and exactly represent phenomena which are 

 fundamental and characteristic of most plants in which a chlorophyll 

 apparatus is completely differentiated, and they do not seem to be open 

 to serious objection on etymological grounds. The adjectives, it will 

 be observed, are analogous to the terms " amylolytic " and " proteo- 

 lytic," which are now commonly used in describing the action of the 

 digestive secretions of animals, and may be used in contrast with these 

 to give a neat expression to an important difference which often exists 

 between the metabolism of animals and that of plants. 



A STROLL NEAR BAILDON, IN FEBRUARY. 



By Wm. West. 



Several weeks ago, I had a few hours in part of the Baildon 

 district, comprising Shipley Glen, and gathered the following plants, 

 some of which I had never noticed before in the district. The list is 

 written partly to induce some of our phanerogamic botanists to help 

 the few cryytogamic botanists in their investigation of our flora, by 

 showing them that if they will only study cryptogamic botany, they 

 will be able to collect at any time of the year, even in a smoky 

 district. If snow happens to lie thick upon the ground, some good 

 work can be done along the courses of rills and streams, even 

 Sphagna can be attacked when you can walk over the frozen swamps, 

 a block of the frozen plants cut on land gently thawed, leaving good 

 specimens. I have not mentioned the most common species. A 

 great many more species occur in the district, but one cannot gather 

 all, if one wished to do so, in a few hours.
