6 YORKSHIRE NATURALISTS' UNION ANNUAL REPORT. 22 2 



on the Carboniferous Flora of Yorkshire, being the first of the 

 reports prepared for the Union's Fossil Flora Committee. The 

 second of these reports is in course of preparation by Mr. Wm. Cash, 

 and will deal with the Flora of the Halifax Hard Bed. 



Part 15, which is devoted to the continuation of Mr. J. Gilbert 

 Baker's ' North Yorkshire,' is now ready for issue to the members, 

 and will very shortly be sent out. 



All the sheets intended for inclusion in Part i6 are printed or in 

 the printer's hands, and it is proposed to issue it about the middle 

 or end of January next. 



When this has been issued, the arrears in the publication of the 

 Transactions, which have for some years been a source of anxious 

 consideration to the Executive, will have been overcome, and it will 

 afterwards be practicable to issue each part during the course of the 

 year for which it is due. 



The Library continues to increase by means of donations 

 and exchanges, and is suitably accommodated in book-cases at the 

 Leeds Mechanics' Institute. 



The Sections of the Union have carefully carried on their 

 work during the year, and it is to their efficient management that 

 much of the success which attends the excursions has been 

 attributable. 



Committees of Research. — This important feature of the 

 Union's work has been further developed during the year by the 

 appointment at the last annual meeting of three additional Com- 

 mittees, all working in conjunction with similar ones of the British 

 Association. 



Of these new Committees, the one for collecting and recording 

 Geological Photographs has worked with remarkable success, as was 

 evidenced by their having contributed the larger portion of the 

 excellent show of geological photographs which was exhibited at 

 this year's meeting of the British Association. 



The Committee for collecting information as to the Disappearance 

 of Plants from their old habitat, has also carried on its work with 

 success, and contributed a larger number of facts to the report which 

 Prof Hillhouse gave to the British Association this year. The 

 detailed Yorkshire report, compiled by Messrs. C. P. Hobkirk, F.L.S., 

 and P. F. Lee, has been pubHshed in 'The Naturalist.' 



The Committee appointed for the investigation of the Crypto- 

 gamic Flora and Invertebrate Fauna of the Freshwaters of 

 Yorkshire has accumulated a number of interesting facts, but has been 

 unable to frame a report, from inability to obtain from the British 

 Association Committee copies of the necessary schedules. This
